【摘要】：目的:探討CT及MRI對隱匿功能性嗜鉻細胞瘤的診斷價值。方法:回顧性分析有完整資料及手術(shù)病理結(jié)果的隱匿功能性嗜鉻細胞瘤4例,均無典型的高兒茶酚胺血癥,4例均行CT檢查,3例行MRI檢查。結(jié)果:瘤體呈類圓形,瘤體直徑≥5 cm者3例,最小者為4.7 cm,邊界清楚,CT平掃密度不均勻,瘤體內(nèi)見低密度壞死囊變區(qū)。瘤體T1WI呈低信號,T2WI以高信號為主,內(nèi)見囊袋狀更高信號,或夾雜低信號;同反相位信號無減低;DWI呈高信號;動態(tài)增強掃描示實性部分快速、明顯強化,邊緣強化顯著。結(jié)論:隱匿功能性嗜鉻細胞瘤瘤體直徑通�！�5 cm;其CT與MRI表現(xiàn)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，
