Spontaneous Rupture of a Simple Hepatic Cyst Complicated With Intracystic Hemorrhage

A 69-year-old female presented with abdominal pain for 3 days without trauma history. Ultrasound examination showed that she had a hepatic cystic lesion, which was enhanced on contrast computed tomography. Surgical intervention was performed 6 days after admission; bloody ascites in the peritoneal cavity, a ruptured cyst 12 cm in size, and a rupture hole over the cystic wall were noted. Spontaneous rupture is an infrequent presentation in a simple hepatic cyst with only a few case reports in the English and Japanese literature. Spontaneous rupture of a simple hepatic cyst with intracystic hemorrhage can pose a problem in differential diagnosis from cystic neoplasm of the liver and needs further management.
