摘要

腎上腺髓質脂肪瘤是相對少見的良性腎上腺腫瘤，解剖研究發現約佔人口比例的0.08%-0.4%。此病灶從腎上腺長出，含有成熟的脂肪組織和造血細胞。病人大多沒有症狀，常於解剖或是其他原因作影像檢查時意外發現。大部分的腫瘤是單側且小於5公分，所以兩側巨大腎上腺髓質脂肪瘤屬相當罕見的病灶。我們報告一名56歲男性的病例，症狀是腹脹六個月。文中將描述典型的電腦斷層特徵並作相關文獻的回顧。

Adrenal myelolipoma is a rare benign adrenal neoplasm presenting in 0.08%-0.4% of population based on autopsy series. It is of adrenal origin composed of mature adipose tissue and a variable amount of hematopoietic elements (myeloid and erythroid cells). Most patients are asymptomatic, and the lesion is discovered incidentally at autopsy or on imaging studies performed for other reasons. Most tumors are unilateral and small in size (＜5cm). The case of symptomatic bilateral giant adrenal myelolipomas is extremely rare. We report a case of bilateral giant adrenal myelolipoma in a 56-year-old male presenting with gradually abdominal distent ion for 6 months. We present characteristic CT finding in this patient with review of literatures.
