Nonparasitic solitary huge liver cysts causing intracystic hemorrhage or obstructive jaundice.
We report two cases of a nonparasitic solitary huge liver cyst. The first case, that of a 42-year-old woman, was admitted with a chief complaint of upper abdominal pain. Computed tomography (CT) scans revealed a huge cyst, 10 cm in diameter, in segments 4 and 5 of the liver, and spontaneous rupture of the cyst with intracystic hemorrhage. Her general condition was improved by transcatheter arterial embolization (TAE). Percutaneous cystic needle aspiration cytological examination revealed no malignant cells, so she was discharged. After 3 weeks, however, the cyst had increased in size, and simple cystectomy was performed. Histological examination proved the cyst to be benign. The patient in the second case, a 70-year-old man, was admitted with epigastric discomfort and obstructive jaundice. CT scans revealed a huge liver cyst, 18 x 15 cm, in the right lobe of the liver, with dilation of the bile duct in the lateral segment. Magnetic resonance cholangiopancreatography showed compression of the left hepatic duct by the cyst and dilation of the bile duct in the lateral segment. Endoscopic retrograde cholangiopancreatography disclosed no communication between the bile duct and the cyst. Percutaneous transhepatic cyst drainage was performed, and minocycline hydrochloride was infused. The cyst was reduced in size, and the reduction has been maintained for 20 months since treatment.
