肾上腺弥漫性大B细胞淋巴瘤声像图特点分析

Sonographic feature of adrenal diffuse large B-cell lymphoma

目的探讨肾上腺弥漫性大B细胞淋巴瘤（ADBCL）的超声声像图特点。方法回顾性分析经病理证实的18例ADBCL患者的超声表现及临床资料，总结其声像图特点，并与增强CT结果对照。结果本组18例ADBCL患者中，单侧4例，双侧14例，共32个病灶。肿块最大直径3．7—13．8cm，平均7．9cm。所有病灶均表现为低回声实质性肿块，81．3％（26／32）肿块形态不规则、呈典型的分叶状；87．5％（28／32）肿块内部回声均匀；75％（24／32）肿块边界清晰，部分有包膜；所有病灶彩色多普勒检查均未见明显血流信号。增强cT肿块显示为软组织密度影，内未见明显强化或轻度强化。结论ADBCL具有特征性的声像图表现，超声检查对其诊断有重要价值。

Objective To explore sonographic feature of adrenal diffuse large B-cell lymphoma （ADBCL）. Methods The ultrasonic appearance and clinical data of 18 patients with ADBCL confirmed by pathology were analyzed retrospectively. Sonographic features were summarized and compared with enhanced CT. Results Among 18 patients with ADBCL, 4 cases were in unilateral adrenal gland and 14 cases were bilateral adrenal gland. A total of 32 lesions were detected. The mean diameter of these tumors was 7.9 cm（3.7~13.8 cm）.All lesions were characterized by hypoechoic substantial mass. 81.3%（26/32） masses had irregular shape and showed typically lobulated. Internal echo of 87.5% （28/32） masses were homogeneous.75% （24/32） masses had clear boundary and partly masses had envelope. Blood signal were not found in all lesions. Enhanced CT showed that masses displayed as soft tissue density, significantly improvement or slight improvement were not found. Conclusion It is of important value for uhrasonography to diagnose ADBCL which has characteristic ultrasonic appearance.
