摘要
目的 探讨CT在肾上腺肿瘤的诊断与鉴别诊断中的价值。方法 回顾性分析58例经手术与病理证实的肾上腺肿瘤病例。结果 皮质腺瘤30例,瘤体直径多为1.0-5.0cm,密度均匀但较低,强化较轻;髓样脂肪瘤8例,瘤体内有特征性脂肪密度;嗜铬细胞瘤12例,瘤体多较大,平扫密度不均,增强后实体强化明显;皮质腺癌3例,瘤体较大,呈分叶状,边界不清,密度不均,增强后环状强化;肾上腺转移瘤5例,多为双侧,瘤体大,呈分叶状,增强实体部分强化。 结论 结合临床特征,CT可较好的诊断肾上腺肿瘤。
Objective To evaluate the value of CT scaning in the diagnosis and differentiation of adrenal tumor. Methods CT findings in 58 patients verified by operation and pathology were retrospectively analyzed. Results Adenoma was found in 30 cases, presenting as 1.0-5.0cm mass of low and homogeneous density with slight enhancement. Myelolipoma was found in 8 cases, presenting as low density area of characteristic fat contents. Pheochromocytoma occurred in 12 cases and was always marked by a large mass of heterogeneous density on plain scans while showed marked enhancement on enchanced scans. Adenocarcinoma was seen in 3 cases, it was manifested as large 、lobulated mass of heterogeneous density with ring-like enhancement. Metastases was found in 5 cases,most of tumor were bilateral ,it was manifested as large 、lobulated mass of heterogeneous density with marked enhancement. Conclusion CT can diagnose most adrenal tumor with clinical signs.
