【摘要】：目的:探讨CT及MRI对隐匿功能性嗜铬细胞瘤的诊断价值。方法:回顾性分析有完整资料及手术病理结果的隐匿功能性嗜铬细胞瘤4例,均无典型的高儿茶酚胺血症,4例均行CT检查,3例行MRI检查。结果:瘤体呈类圆形,瘤体直径≥5 cm者3例,最小者为4.7 cm,边界清楚,CT平扫密度不均匀,瘤体内见低密度坏死囊变区。瘤体T1WI呈低信号,T2WI以高信号为主,内见囊袋状更高信号,或夹杂低信号;同反相位信号无减低;DWI呈高信号;动态增强扫描示实性部分快速、明显强化,边缘强化显著。结论:隐匿功能性嗜铬细胞瘤瘤体直径通常≥5 cm;其CT与MRI表现具有一定特征性。
[Abstract]:Objective: to evaluate the diagnostic value of CT and MRI in occult functional pheochromocytoma. Methods: four cases of occult functional pheochromocytoma with complete data and surgical and pathological results were retrospectively analyzed. All the 4 cases without typical hypercatecholamia were examined by CT and 3 cases with MRI. Results: the tumors were round in shape, with the diameter 鈮，
