摘要
本文报告经手术病理证实的14例肾上腺髓脂瘤,全部为右侧。CT表现均为肾上腺区域内边缘光滑锐利的类圆形肿块。其内脂肪区域的CT值低于-30HU,低密度区的CT值近似或略高于正常脂肪,其余部分为团块状和索条状分隔阴影,近似软组织密度。CT表现能反映肿瘤的病理结构。根据其部位、密度值、内部结构、边缘以及脂肪部分不增强等特点,CT能在术前作出组织学诊断。本组14例均根据CT表现术前确诊。看来CT在建立肾上腺髓脂瘤的术前确诊中优于超声和普通X线检查,包括静脉尿路造影和血管造影。本文还讨论了髓脂瘤的病因、病理和肾上腺区域内脂肪性肿瘤的鉴别诊断。
Fourteen cases of adrenal myelolipoma proved by surgery and pathology are reported. All cases were in the right. CT of 14 cases revealed sharply marginated suprarenal mass, usually round or oval. The CT number were less than-30 HU. Their radiolucency was equal to or greater than normal fat, the remainder were of round soft mass or multiseptated streak soft trssue CT appearance may represent pathologic findings. By evaluating location, as well as the lack of contrast enhancement in the fatty portion, it seems that a specific histologic diagnosis can be made preoperatively by CT. According to CT appearance in our series, all of 14 patients established the correct diagnosis before operation. It seems that CT is superior in the preoperative diagnosis of adrenal myelolipoma to u'trasound and conventional radiologic examination including intravenous urography and angiography The etiology and pathology of myelolipoma as well as the differential diagnosis of fatty tumor in the suprarenal area are also discussed.
