Rapidly evolving non-parasitic hepatic cyst.

A case of solitary non-parasitic hepatic cyst is presented; its evolution appears to have occurred rapidly (10 months). This and all previously reported cysts are unassociated with any clearly diagnostic signs, symptoms, laboratory or x-ray findings. The treatment of choice is total surgical extirpation since the incidence of recurrence of the cyst is appreciably high with subtotal excision, drainage, and marsupialization. This disease has been reported to carry a mortality of 5.1% to 6.6%.
