Rare case of adult pancreatic hemangioma and review of the literature

Pancreatic hemangiomas are a rare type of cystic tumor, with very few cases reported in the literature. Herein, we present the case of a 28-year-old woman who was admitted to our hospital for abdominal pain. A physical examination failed to reveal any abnormalities that could explain her symptoms. A contrast-enhanced computed tomography showed a multilocular cyst with moderately enhanced septa and fluid-fluid levels in the body and tail of the pancreas. A serous cystadenoma or pseudocyst of the pancreas was initially suspected, and the patient underwent a subtotal pancreatectomy and splenectomy. The pathologic diagnosis was a pancreatic hemangioma. This is the second case of pancreatic hemangioma with fluid-fluid levels reported in the literature. Upon imaging, the presentation of this tumor can resemble serous or mucinous cystadenomas, pseudocysts of the pancreas, and side-branch type intraductal papillary mucinous neoplasms. This report reviews the clinical symptoms, radiologic features, pathologic characteristics, differential diagnoses, and treatment of this rare lesion type.
