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.

Hydosalpinx vs. pyosalpinx. Hydrosalpinx: Anechoic simple fluid with thin wall. When chronic, see “beads-on-a-string” sign: Short, round, 2-3 mm projections seen along inner tubal walls in cross section representing flattened, fibrotic remnants of endosalpingeal folds. Pyosalpinx: Echogenic purulent fluid with thick wall. “Cogwheel” sign: Thickened endosalpingeal folds in setting of acute inflammation. In this case, pyosalpinx is adherent to ovary with adjacent inflammatory fluid. Dilated tube may fold upon itself forming C-shaped or S-shaped cystic mass with incomplete septations common.
