肾上腺淋巴瘤的超声诊断

Sonographic Diagnosis of Adrenal Lymphoma

目的探讨肾上腺淋巴瘤的超声声像图特点,评价超声对该病的诊断价值。资料与方法回顾性分析12例经病理证实的肾上腺淋巴瘤患者的超声表现,评估病变的大小、形态、边界、内部回声及血流情况。结果 12例患者中,9例为双侧受累,3例为单侧,共21个病灶。病灶大小3.1～12.7cm,平均(7.8±3.7)cm。肿块形态呈不规则形12个,呈椭圆形或类圆形7个,呈肾上腺弥漫性增厚表现2个,类似于肾上腺增生。肿块内部主要表现为低回声,内部回声均匀12个,回声不均匀9个,其中4个内部可见条状高回声,3个内部可见片状无回声区。肿块边界清晰16个,边界不清5个。彩色多普勒血流显像示大部分病灶血流信号稀少或无明显血流信号。结论肾上腺淋巴瘤超声声像图表现具有一定的特征性,超声检查有助于与肾上腺其他肿瘤鉴别。

Purpose To explore the sonographic characteristics and its diagnostic value of adrenal lymphoma.Materials and Methods Twelve patients with adrenal lymphoma confirmed by pathology were retrospectively reviewed.Important parameters such as size,morphology,margin,internal echogenicity and blood supply of these lesions were evaluated.Results The diameters of 21 lesions（including 9 bilateral lesions and 3 unilateral lesions） were 3.1-12.7 cm,median（7.8±3.7） cm.Twelve lesions were irregular,7 lesions were round or oblong,and 2 lesions presented as adrenal thickening similar to appearance of adrenal hyperplasia.As for internal echogenicity,12 lesions were markedly homogeneous hypoechoic,while the remaining 9 lesions were inhomogeneous hypoechoic corresponding to the cystic and central echogenic areas.Sixteen lesions were well-defined,and 5 had ill-defined margins.CDFI showed little or no blood flow signal in the majority of lesions.Conclusion The sonographic changes of adrenal lymphoma have certain characteristics,which may be helpful in differential diagnosis.
