肝臓原発カルチノイド腫瘍の1例

A case report of primary hepatic neruroendocrine tumor（carcinoid tumor）

肝臓カルチノイド（neuroendocrine tumor：NET，神経内分泌腫瘍）は消化管や膵などからの転移性腫瘍が多く，肝原発は非常にまれである。今回，CTやMRIの所見，術前診断に関する臨床的な事項を中心に若干の文献的考察を加えて報告する。

Abdominal CT & MRI revealed solid & cystic lesion in right to left hepatic medial lobe, measuring 17×13×15 cm in a 44 years-old male. Dynamic CE-CT and MRI showed hypervascular tumor with multiple T1WI high signal portions and several cystic areas with fluid-fluid level. It also had a T2WI low signal rim representing frbrous capsule. No other lesions were found by the radiological investigations. Surgical resection was performed and histopathological examination revealed a primary hepatic neruroendocrine tumor G2（carcinoid）.
