Which of the following would be the most worrisome sonographic finding?

A 4 cm, smooth, oval mass with cystic areas in the breast of a 55-year-old woman

A 39 year old man is seen with right-sided painless scrotal swelling. Sonographic examination reveals the appearance shown. What is the most likely explanation for this appearance? Where else should the sonographer investigate?

A large right sided varicocele can be caused by extrinsic compression of the right testicular vein, and examination of the right upper quadrant revealed an occult lower pole renal cell carcinoma.

An 83-year-old man saw his rural family medicine physician with complaints of overall weakness, joint pain, and generally "not feeling well" for the last 9 months. The patient had been quite active for his age before 1 year ago. After taking a careful history and completing a thorough physical examination, the clinician ordered labs including PSA. On receiving the PSA results of 23 ng/mL, the physician also requested a prostate sonogram and a nuclear medicine bone scan. The patient was scheduled for a consultation visit with his physician, who gave the patient what news regarding his current state of health?

Prostate cancer

The PSA density result in an asymptomatic 65 year old African American man is 0.2, and DRE reveals a nodule. What is the likely dx?

Prostate cancer

A 32-year-old man woke up with intense pain, which he described as "a constant, deep, throbbing pain behind his scrotum." The patient's temperature had been elevated for a few days, and he had felt intermittent fever and chills for about the same length of time. The primary care physician ordered routine laboratory tests and TRUS examination of the prostate. His laboratory test results showed an elevated PSA and white blood cell count. The sonogram showed a diffuse increase in color flow Doppler in the prostate gland and an irregular, cystic structure at the junction of a seminal vesicle and prostate. What is the most likely diagnosis?

Prostatitis can cause the "constant, deep, throbbing pain" as described by this patient. The irregular, cystic structure at the junction of the seminal vesicle and prostate coupled with an elevated white blood cell count would lead one to consider abscess.

Findings are most consistent with?

The nodule in the right lobe is noted to be mostly cystic but contains debris. The nodule in the left lobe contains multiple microcystic spaces separated by thin septa. These findings almost certainly suggest:

Bilateral benign thyroid nodules

A 50 year old woman palpates a compressible, mobile mass in her left breast. Sonographically, the mass, although palpable, is indistinguishable from the surrounding breast tissue. What would be the most likely dx?

Lipoma

An elderly man with a painless, palpable thyroid nodule is referred for thyroid sonography. Previous imaging studies have reported "a thyroid nodule with calcifications." The images are not available for review. A second sonogram is performed and reveals a 2 cm x 3 cm solid, hypoechoic nodule with a hypoechoic halo and disruption of peripheral, eggshell calcification. These findings make this nodule suspicious for:
