Bleeding into the subarachnoid space, where the cerebrospinal fluid circulates.

After receiving health insurance through the affordable care act, a 55-year-old man is encouraged by his wife to see a family physician for a check-up for the first time in over a decade. The physician assistant noted that the man spent several minutes taking deep breaths and expiring through pursed lips while sitting in a tripod position when he came in the room, but that this subsided over time. During the physical, the physician notices a barrel chested appearance and that his fingernails have a distinct rounded appearance to them. The physician also notices a bluish tinge to the patient's lips. Body temperature is 980C Blood pressure is 138/85, Heart rate is 90 BPM and respiratory rate is 25 breaths per minute. Auscultation is relatively normal, except for Rhonchi in the vicinity of the secondary bronchi. The physician inquires into the patients medical history. He describes a 60 pack-year history of smoking and a "smoker's cough" that is typically worse when he first wakes up in the morning. Aside from the normal problems that happen with aging, the patients describes himself as being in "pretty good health, all things considered".

COPD (chronic obstructive pulmonary disease)

chronic subdural hematoma

CT scan through the brain of an elderly patient demonstrates a subdural haemorrhage with acute and chronic components. Note how the acute blood sinks inferiorly (haematocrit effect). A similar appearance can rarely be seen in acute haemorrhage in patients on anticoagulants, where the blood separates into serum and haematocrit rather than clotting.

While standing on the sidelines, Drew Bledsoe demonstrated untypical restlessness and agitation, and was assessed further in the locker room. As he was packing his belongings, he kept complaining about a painful shoulder. The doctors felt something was not quit right, and so sent him for a consultation with an internist at Mass General.

accumulation of blood in pleural space

A patient makes an appointment with his family physician searching for a treatment for laryngitis. The physician uses a laryngoscope to view the vocal folds, and is surprised to note that there is no discernable inflammation. The physician asks the patient to alternate between saying "aaah" and taking deep breaths and notes that the left vocal fold does not move properly with the right (see video). Among other tests, the doctor refers the patient for angiography. What artery is the doctor interested in viewing?

aortic arch (impinges on left recurrent laryngeal nerve)

A 48 year old woman reports to the ER complaining of severe pain in her shoulder that is beginning to radiate down her arm. During the physical examination the physician notices a firm mass in her right anterior neck and dilation of the external jugular vein (see video). Palpation of the mass creates a pins and needles sensation down her arm. The physician also notices that the patient's right eyelid is drooping. Shining a penlight in the patient's eyes, she notices that the right pupil is fixed and constricted. A plain film radiograph is ordered.

brachial plexus

A teenager presents to the emergency room with orbital swelling. About a week ago the patient reported experiencing frequent headaches in the "back of his eyes" and yesterday developed blurred vision. He woke up this morning with a fullness in his left orbit. After seeing his reflection in a mirror, he called down to his mother, who rushed him into the hospital. The patient does not recall having suffered any significant head trauma. The physician does note that the patient's skin is noticeably pock marked (acne). What is the most likely diagnosis?

cavernous sinus thrombosis

A 64-year-old female with severe depression had become dehydrated after a prolonged period of self-starvation and refusal to drink. In order to rehydrate the woman, a central line was place in the subclavian vein for administration of a rehydration solution. The patient showed improvement over a period of 2 days, then suddenly developed tachypnea, cyanosis, tachycardia, and hypotension. Blood work and a chest film was ordered. What caused the sudden onset of the above symptoms?

collapse of apicoposterior bronchopulmonary segment

A 46-year-old man was referred to a neurology clinic with a 2-year history of recurrent vertigo. During the first attack, an initial period of acute severe vertigo lasting several minutes was immediately followed by sensorineural hearing loss and imbalance. The patient was treated with intravenous infusions and symptoms resolved completely. The second episode of severe vertigo occurred 18 months later, accompanied by right-sided aural fullness and high-frequency nonpulsatile tinnitus, this time without hearing impairment. Six months after the second episode, the patient started to suffer from recurrent episodes of severe vertigo lasting from several minutes to hours, which were incapacitating and significantly impaired the patient's ability to work or carry on with his regular activities. Symptoms were lessened with bed rest. Both frequency and intensity of the vertigo attacks increased over the following months. Two months ago the attacks occurred at least several times a week, sometimes daily. The patient is also contending with persistent fluctuating high-frequency tinnitus and increasing aural fullness on the right side. All other aspects of his neurological examination was normal. Audiometric testing showed no significant hearing impairment and vestibular testing was normal, what nerve is affected?

cranial nerve 8 (vestibulococlear)

Frey's syndrome is a unique condition that follows a parotidectomy. Residual parasympathetics establish connections with sweat glands that cause the person to perspire when they eat. What nerve does this stimulation originate from?

cranial nerve 9 (glossopharengeal)

A 32-year-old man was referred to a rehabilitation clinic with left shoulder dysfunction. The physical therapist identifies weakness with shoulder elevation and develops a rehabilitation program for the patient. Two weeks into treatment, the patient calls to reschedule a session due to a conflicting doctor's appointment. The patient explains in the following session that he was also referred to an ENT specialist, due to sore throat, left earache, hoarseness, and swallowing difficulty, which developed three weeks prior to the left shoulder issues. The PT consults with the ENT physician about his own assessment and learns that the patient's left vocal cord was hypomobile, that he showed an impaired gag reflex on the left side and deviation of the uvula to the right side. There was no impairment of facial sensation and motion, no tongue deviation or nystagmus. The PT begins to believe that the patient's diverse medical complaints can all be attributed to a single medical condition affecting 3 different cranial nerves, what three nerves are involved?

cranial nerves 9,10,11 (glossopharyngeal, vagus, accessory)

A 53-year-old man appeared in the ER complaining of pain and distension in his abdomen that had progressed over the past several days. He had originally attributed the pain to indigestion and bloating, but has become concerned that the bloating has continued to increase, despite not eating. During the patient history, the man admits to eating fast foot takeout almost every day, and to smoking a pack of cigarettes and drinking a liter of burbon on an almost daily basis going on 20 years. Inspection of the abdomen reveals distension and the prominence of the superficial veins.

A 45 year old woman presents to her family physician. An avid runner, she has been noticing a progressive decrease in exercise performance over the past year. She originally attributed this to the effects of aging. During a group run earlier in the week, however, she was forced to pull back, and one of her running mates who chose to stay with her became alarmed to notice a blue tinge develop around the patient's lips. A thorough history reveals that the patient has also become susceptible to dizzy spells, and recalls several moments of almost passing out, particularly after coughing spells. Among other things, the physician orders cardiac ultrasonography...

A 52 year old male presented to the emergency department with severe left flank pain radiating to the right lower quadrant. His blood pressure was 154/96, pulse rate was 79 bpm, respiratory rate was 24 breadths per minute and temperature was 36.7° C. The pain was insidious in onset and had an intensity of 10/10 on verbal analog scale which decreased to 8/10 after administration of Toradol and Morphine medications provided in the emergency department. The pain was constant, lasting 3 hours in duration, and he had two episodes of vomiting since its onset. He did not report experiencing any chest pain, dyspnea, fever or bowel and bladder dysfunction. His heart rate and respiration were within normal limits. He did not display any signs of edema or nausea, abdominal discomfort or indigestion. His abdomen was soft with diffuse tenderness, which increased over the right lower quadrant. Urinalysis revealed a moderate increase in specific gravity (1.030), significant hematuria (3+) and a trace of protein.

An 83-year-old male is brought to the emergency room by his distraught daughter. The patient is a widow, having lost his wife of 55 years to an acute MI 3 years earlier. He speaks with his daughter, who lives several hours away, over the phone every few days. In recent months, the patient has complained to his daughter about feeling constantly nauseated, especially after eating. While the daughter expressed concern, the patient said it was likely nothing serious, as he was not running a temperature. Two weeks ago the symptoms progress to a complete loss of appetite and vomiting when he did attempt to eat. The daughter became increasing concerned at the lack of improvement and decided to come out to see him. Upon her arrival, she is alarmed by her father's appearance and immediately (yellowing skin) rushes him to the ER for assessment. An MRI and CBC are ordered.

A young girl is seen in the ER after sustaining a serious head injury from a fall. While closing down their backyard pool for the fall season, the parents became distracted and did not see the young girl inch her way closer to the pool's edge. They turned in time to see her fall in and land on her head. The girl lost consciousness and was rushed to the ER, regaining consciousness on the way. Head CT images were negative for fracture or cranial bleeds. The family is released and instructed on concussion protocol. Two weeks after the incident, the wife follows up with a check-up with her family doctor. She has noticed abnormal movement of the child's eyes. During the examination, the doctor notices that the girl keeps her head tilted towards the right shoulder. She is referred to an opthamologist, who does a series of tests. Cover/uncover tests are normal when the child's head is tilted to the right, but abnormal when the head is held in a neutral position. Which cranial nerve is affected?

trochlear nerve palsy

A woman experiences difficulty during a vaginal childbirth in the maternity ward of a local hospital. During delivery, the child's left shoulder becomes caught at the level of the symphysis pubis. After much manipulation, the obstetrician is able to clear the shoulder through the birth canal, and the delivery progresses normally. APGAR scores are within normal levels, and the baby appears healthy, with the exception of a slight cyanotic appearance. A ultrasound is ordered, and no abnormalities are found in heart wall structures. The cyanotic appearance persists in the weeks following delivery, and during a follow up visit, the physician notes diminished breath sounds over the entire left lung. A fluoroscopic analysis is performed...

A 59-year-old man with a history of hypertension presents for an elective subtotal colectomy for colon cancer. The procedure is successful, without any signs of complication. His immediate postoperative state is stable, but on postoperative day 4 he develops sudden-onset shortness of breath. He denies having any chest pain, palpitations, nausea, or diaphoresis (excessive sweating). On physical examination, his blood pressure is 138/68 mm Hg; his pulse is regular, with a rate of 110 beats/min, and his respiratory rate is 30 breaths/min. His temperature is 97.7°F and his oxygen saturation is 92% on room air, which improves to 98% on 2 L of oxygen via nasal cannula. He is in mild respiratory distress but is able to speak in full sentences. He is not recruiting the accessory muscles of respiration. The examination of his head and neck is normal. He has mildly decreased breath sounds at his right lung base. His heart sounds are normal. His abdomen is soft, nontender, and mildly distended with good bowel sounds; a midline incision scar is clean and nontender. He has palpable peripheral arterial pulses in his upper and lower extremities. The patient did not have edema or tenderness in the lower extremities. Laboratory blood tests are normal. An arterial blood gas on room air demonstrates a pH of 7.45, a pCO2 of 32 mm Hg, and a pO2 of 62 mm Hg, with an oxygen saturation of 93%. A chest x-ray reveals bibasilar subsegmental atelectasis. He receives a treatment session with a respiratory therapist, but his condition continues to deteriorate. On postoperative day 5 his oxygen saturation declines despite supplemental oxygen and he is intubated for hypoxemic respiratory distress. He is transferred to the ICU.

Frank, a 59-year-old man is brought to the ER by his wife, Erma. The couple had been sitting out on the front porch of their home enjoying the sunset (after dinner) when the man started to experience the gradual onset of chest pain. Fearing a heart attack, the wife insisted they visit the local emergency room. The patient describes a burning sensation in the midthoracic region. The doctor also notes that couple has been arguing about the husband sitting in the chair; Erma wants the husband to lie down, but Frank insists that this makes the pain worse.

An 85-year-old man is presented to the emergency department (ED) by ambulance with severe abdominal pain that began suddenly 2 hours before presentation. The pain is mainly in his back and radiates toward his left inguinal region. The patient felt light-headed at the onset of the pain to the extent that he had to grip the sink to steady himself. He also reports significant nausea, although he has not vomited. He has no urinary symptoms. His medical history includes type 2 diabetes, hypertension, hyperlipidemia, ischemic heart disease, and intermittent claudication (cramping pain) of his lower extremities. He smoked 10-20 cigarettes a day for over 60 years but stopped 5 years ago. The physical examination reveals tenderness in the left iliac fossa and left costovertebral angle. His vital signs are remarkable for a heart rate of 105 beats/min and a blood pressure of 110/90 mm Hg. An abdominal CT is taken.

ruptured abdominal aortic aneurism

Following the treatment for his kidney stone, the same patient returns to the clinic 3 weeks later with a similar pain presentation. The patient explains that the pain had had a more gradual onset than before, and had suddenly worsened this morning, accompanied with feelings of lightheadedness and weakness. The patient's vital signs at presentation were: heart rate, 96 beats/minute; blood pressure, 133/76 mm Hg; respiratory rate, 20 breaths/minute; and temperature, 98.9˚F. Oxygen saturation was 98% on room air. On physical examination, the patient had left lower quadrant pain and left costovertebral angle tenderness. Plain film radiographs showed nothing of significance. Laboratory studies were remarkable for a hemoglobin level of 6.8 g/dL, and a hematocrit of 21.1%. Based on the patient's history and symptoms, axial and coronal computed tomography (CT) scans were ordered...

ruptured renal calyx

A 27 year old woman is seen by her obstetrician 6 months following the birth of a health baby boy for a routine check-up. An avid exercise enthusiast, she returned to running and weight training a few weeks following an uneventful vaginal delivery under epidural anesthesia, and jokes with her doctor at how jealous her friends are with how quickly she lost her "baby bulge". During the examination, however, the woman confides in her doctor about a protrusion along her midline, just above the belly button. She first noticed it mid-pregnancy, in particular while doing abdominal crunches, and assumed it was a natural progression of the developing uterus, but is now frustrated by the fact that it does not seem to be disappearing. She says it is not painful, but she is becoming concerned and frustrated by the lack of improvement.
