Spontaneous rupture of a nonparasitic liver cyst complicated by intracystic hemorrhage.
a case of spontaneous rupture of simple liver cyst complicated by intracystic hemorrhage is described. This rare condition was detected in a 61-year-old man who underwent left trisegmentectomy of liver under a suspected diagnosis of cystadenocarcinoma because of elevated serum levels of carbohydrate antigen (CA) 19-9 and DUPAN 2, and the presence of an intracystic structure. The resected specimen showed a benign liver cyst with intracystic hematoma and high levels of CA19-9 and DUPAN 2 in the cystic fluid. It is suggested that cyst rupture may increase serum levels of tumor markers whose levels are high in the cystic fluid, and that repeated observations of an intracystic structure may be the most reliable method to distinguish intracystic hemorrhage from cystic neoplasm.
