title: A case of spontaneous rupture of a simple hepatic cyst.
abstract: We describe the spontaneous rupture of a simple hepatic cyst associated with a benign course. A 64-year-old woman was admitted for right upper quadrant pain. The patient denied a history of abdominal trauma. Abdominal computed tomography (CT) showed a huge solitary hepatic cyst (diameter, 10 cm) in the right lobe. Part of the cyst surface was irregular, and the interior was heterogeneous on ultrasonography. Fluid retention was detected under the liver capsule. Spontaneous rupture of a nonparasitic hepatic cyst was suspected. The patient was admitted to our hospital for further evaluation and treatment. Examination of the abdomen revealed right upper quadrant pain but no signs or symptoms of peritonitis. One week after admission, CT revealed that the volume of fluid retained under the liver capsule had decreased. Percutaneous puncture was performed with a needle and an 8-French pigtail catheter under ultrasonographic guidance. Serous, brown fluid was aspirated. After percutaneous aspiration, the patient's symptoms resolved. Minocycline hydrochloride was given daily by intravenous injection for 7 days. The catheter was then removed. There has been no evidence of recurrence after 1 year.
