lymphadenopathy is commonly seen in people with what

AIDS

The anterior, called ---, and posterior, called ---, perirenal fascia divide the retroperitoneum coronally into three compartments

Anterior- Gerotas Posterior- Zuckerkandls

A fecalith or calcification found in the appendiceal lumen.

Appendicolith

Which of these are commonly seen with metastatic cancers of the ovary, colon, and stomach?

Complex ascites Omental caking Peritoneal implants

Located at the right lateral aspect of the lesser sac and is the opening communicating with the greater sac.

Foramen of Winslow

____________________________ refers to free blood within the peritoneal cavity.

Hemoperitoneum

What is the most common primary malignancy of the retroperitoneum?

Liposarcoma

What sign is seen on U/S representing anterior and posterior node masses surrounding mesenteric vessels

Mesenteric sandwich

This potential space is created by the peritoneum, reflecting from the liver over to the right kidney.

Morrison's pouch

This is a chronic inflammatory process that results in fibrous tissue proliferation affecting and encasing the great vessels, ureters, and lymphatics of the retroperitoneum. (Hint - ureters are frequently obstructed)

Ormond's disease

A rare, borderline malignant process that results when a benign appendiceal or ovarian adenoma ruptures, spilling epithelial cells into the peritoneum.

PMP

A diagnostic or therapeutic procedure performed to remove ascites from the peritoneal cavity.

Paracentesis

Ascites typically collect in the

Paracolic gutters and Morrison's Pouch.

The kidneys and the adrenal glands lie in what space?

Perirenal space

This lesion typically appears as a thick-walled fluid collection that may contain ischemic tissue, pus, and blood components. It is caused by an inflamed or perforated organ, surgical complication, or a parasite.

Peritoneal abscess

Rare, primary malignant tumor that is associated to asbestos exposure.

Peritoneal mesothelioma

The quardratus lumorum and psoas muscles lie posterior to the _________ and are separated from this space by their own fascia.

Posterior pararenal space

The crus of the diaphragm is located:

Posterior to all structures except for the Ao

Another name for Ormond's disease

Retroperitoneal Fibrosis

posteriorly located compartment that lies between the posterior portion of the parietal peritoneum and the transversalis fascia (posterior abdominal wall muscles). Extends from the diaphragm to the pelvis.​

Retroperitoneum

An extraperitoneal potential space located between the anterior wall of urinary bladder and the pubic symphysis.

Space of Retzius

SADPLUCKER

Superior Mesenteric Artery/Vein & Splenic Artery/Vein​ Aorta/IVC & Adrenal glands​ Duodenum (2nd - 4th parts) & Distal CBD​ Pancreas/Prostate​ Lymphatics​ Ureters​ Colon (Ascending and Descending)/Cru of Diaphragm​ Kidneys​ Esophagus​ Rectum​

The Greater Omentum is divided into which two compartments?

Supracolic and Infracolic

This type of ascites is characterized by the lack of protein and cellular materials in the fluid. It is often associated with PHTN and CHF.

Transudative

Characterized by a lack of protein and cellular materials in fluid. Typically has a simple appearance and is often associated with PHTN and congestive cardiac disease.

Transudative ascites

What is the name of the condition that involves bowel wall thickening and is confined to the colonic mucosa and submucosa?

Ulcerative colitis

The potential space created by the peritoneal reflection over the uterine fundus, broad ligament, and the posterior urinary bladder.

Uterovesicle space

A retroperitoneal _______________________ may develop as an extension from an adjacent organ such as renal infection, diverticulitis, and Chron's disease or due to an existing retroperitoneal fluid collection that has become infected.

abscess

adenopathy

also called lympadenopathy; enlargement of the lymph nodes due to inflammation, primary neoplasia, or metastasis

urinoma

an extravasated urine collection due to a tear of the urinary collection system

Teratomas can contain

cartilage, teeth, bone, and soft tissue

The colon extends from ileum to anus. Divided into segments called haustra, it is largest at the ____________ ____________.

cecal end

Most common cause of ascites

cirrhosis

The peritoneal cavity is divided into 4 quadrants or into 9 regions. What region lies between the right and left hypochondriacs?

epigastric

two compartments of the Peritoneal cavity

greater sac & lesser sac

second most common retroperitoneal malignancy

leiomyosarcoma

lymph nodes are described based on their

location

enlargement of lymph nodes caused by inflammation, primary neoplasia, or metastasis

lymphadenopathy

What is a distension of the appendix by mucus?

mucocele

Potential spaces or grooves found along the lateral ascending and descending colon that conduct fluids between the supracolic compartment of the abdomen and the infracolic compartment of the inferior abdomen and pelvis.

paracolic gutters

This space in the retroperitoneum lies between the posterior renal fascia and the transversalis fascia and contains no organs, only fat.

posterior pararenal space

The pelvic retroperitoneum is divided into four subdivisions. The presacral space is located between the ________ and fascia covering the ________ and posterior pelvic floor musculature.

rectum, sacrum

Organs found within the greater sac:

spleen, cecum, ileum, upper 2/3 of rectum

Lymph nodes that lie posterior to main vessels provide the most reliable indicator of lymphadenopathy since they frequently displace _____________________________.

the IVC and Aorta anteriorly.

The greater omentum hangs from

the greater curvature of the stomach like an apron surrounding the area to wall off infection

A seroma is a fluid collection composed of blood products located adjacent to or surrounding ____________________ organs in the early postsurgical period.
