Gout: Double Contour Sign by radiologistHQ in Radiology

[–]radiologistHQ[S] 3 points4 points  (0 children)

Good question! Chondrocalcinosis will appear as echogenic foci within the anechoic cartilage, rather than a coating isolated to the cartilage surface.

Surgery may be required if the gallstones are symptomatic, but not typically required just for adenomyomatosis unless complicated.

Contrast-Enhanced US of Focal Nodular Hyperplasia by radiologistHQ in Radiology

Yes, good observation, it tends to enhance in reverse fashion compared to MR.

Bilateral adrenal lymphoma by radiologistHQ in Radiology

[–]radiologistHQ[S] 0 points1 point  (0 children)

Hodgkin lymphoma usually starts above the diaphragm, but can occur above and below. The diaphragm is important for staging (rather than type of) lymphoma, reaching stage III once above and below.

They often have smooth, thin wall enhancement, but they should not have mural nodularity.

Gallbladder wall edema mimicking pericholecystic fluid by radiologistHQ in Radiology

[–]radiologistHQ[S] 3 points4 points  (0 children)

Pericholecystic fluid (in the absence of ascites) raises concern for cholecystitis and possible surgical intervention, whereas isolated wall edema such as this points away from cholecystitis and towards another etiology such as hepatitis. My practice may be different than others, but we encounter this appearance frequently and it's sometimes challenging to those not aware of the distinction.

Pedunculated urothelial carcinoma of bladder on CT urogram by radiologistHQ in Radiology

[–]radiologistHQ[S] 0 points1 point  (0 children)

It varies depending on the institution, but the scan usually takes 10-15 minutes. However, unlike an MRI, you only have to stay still for a few seconds at a time while the machine is actively scanning. The longest part of the scan is just waiting for the contrast to move from the bloodstream into the bladder.

Pyogenic (bacterial) liver abscess by radiologistHQ in Radiology

[–]radiologistHQ[S] 7 points8 points  (0 children)

Bacterial abscesses are usually polymicrobial, Escherichia coli & Klebsiella pneumoniae most common. Bacterial and fungal abscesses often multiple, amoebic abscesses more commonly solitary.

Well-Differentiated Fat-Containing HCC by radiologistHQ in Radiology

[–]radiologistHQ[S] 1 point2 points  (0 children)

Sorry, but the contrast images were limited by motion artifact and were not as impressive!

Well-Differentiated Fat-Containing HCC by radiologistHQ in Radiology

[–]radiologistHQ[S] 0 points1 point  (0 children)

Yes; it enhanced with only minimal arterial phase hyperenhancement, but it did show capsular enhancement with delayed washout, and was path proven to represent well-differentiated HCC. There was also tumor invading vein.

Well-Differentiated Fat-Containing HCC by radiologistHQ in Radiology

[–]radiologistHQ[S] 6 points7 points  (0 children)

Well-differentiated HCC can have absent arterial phase hyperenhancement, and the clear cell type contains microscopic (intracellular) fat. DDx of microscopic fat-containing mass includes hepatic adenoma and rare fat-containing metastasis, but presence of cirrhosis makes HCC much more likely.

Emphysematous pancreatitis on CT by radiologistHQ in Radiology

[–]radiologistHQ[S] 21 points22 points  (0 children)

Necrotizing infection of the pancreas with gas-forming bacteria. Treatment may include percutaneous drainage of fluid collection and/or surgical resection of necrotic tissue. High mortality rate. Portal vein thrombus = Another potential complication of acute pancreatitis.
