Transdiaphragmatic extension of hepatic hydatid cyst.

Transdiaphragmatic extension of hydatid cyst (HC) or cystic echinococcosis (CE) of the liver is a rare phenomenon. We report a case that presented as a right middle lobe consolidation. The diagnosis of transdiaphragmatic extension of hepatic hydatid cyst was suspected on CT scan of the chest and abdomen, and confirmed operatively. A successful outcome was achieved by a combination of pre- and post-operative albendazole therapy combined with surgery.
