Magnetic Resonance Imaging Features of Uncomplicated Hepatic Adenoma: A Case Report

肝臟腺瘤的磁振造影影像:病例報告

摘要


由於影像學的進步,無症狀的肝臟腺瘤的診出率在近年來逐漸增高。本文報告一四十七歲女性,在體檢時偶然發現一肝臟腫瘤,經完整影像學檢查後接受手術,證實為一並未合併出血或壞死之肝臟腺瘤。回溯病史發現病患曾在六年前接受皮下注射長效避孕藥。病灶在T1加權影像及在抑制脂肪訊號後之T2加權影像中均呈現與周圍正常肝臟組織相同之訊號強度,但在抑制脂肪訊號後之T1加權影像中則呈現一低訊號區。在動態掃描中,病灶在動脈期中呈現稍微顯影增強。在臨床症狀及病史相符時,肝臟腺瘤在磁振造影上之表現將有助於其診斷。

並列摘要


Hepatic adenomas (HAs) are incidentally detected with increasing frequency after imaging the abdomen for unrelated pathology. We report the radiological findings in an asymptomatic 47-year-old female with an uncomplicated HA, who received the subcutaneous implant of contraceptive Norplan six years ago. MRI showed a well-defined mass in the liver, which was isointense in the T1-weighted and fat-suppressed T2-weighted images, but became hypointense in the fat-suppressed T1-weighted images. Enhanced dynamic scan showed minimal enhancement in the arterial phase. Recognition of such MRI features will help us to suggest the possibility of uncomplicated HAs in the appropriate clinical setting.
