[Invasion of the portal vein by a hydatid cyst. Review of the literature].
We have found only 3 publications in the literature that describe portal vein invasion by a hydatid cyst. This complication is very uncommon but should be kept in mind in the diagnosis of anaphylactic shock. Clinical presentation can vary from abdominal pain and fever to portal hypertension or anaphylactic reaction due to leaking of antigenic material from the cyst. Ultrasound and computed tomography scan can identify hydatid cysts and cavernomatosis, but magnetic resonance imaging shows the presence of multiple daughter vesicles replacing the lumen of the portal vein and a communication between the residual cyst and the portal vein. The treatment of choice is surgery, including removal of the cyst and local instillation of scolicide solution. In addition to surgery, administration of albendazole is recommended. Administration should begin 4 days before extirpation and should be continued for more than 4 weeks.
