肾上腺非霍奇金淋巴瘤的超声影像学表现

目的 探讨肾上腺非霍奇金淋巴瘤的声像图特征。方法 回顾性分析经穿刺活检或手术病理证实的13例肾上腺淋巴瘤的超声声像图特征。结果 13例肾上腺淋巴瘤患者累及双侧6例,单侧7例,共19个病灶,均为非霍奇金淋巴瘤弥漫大B细胞型。肿块大小3.0~14.0 cm,平均(7.99±3.08)cm。18个病灶为低回声,1个表现为杂乱回声。内部回声均匀者10个,不均匀者9个,其中内部可见条索状稍强回声者7个,伴小片状无回声区4个。彩色多普勒示68.42%(13/19)肿块内未见明显血流信号,仅31.58%(6/19)内探及点状血流信号。此外,3个较大病灶不同程度累及同侧肾脏及其周围组织,1个伴下腔静脉栓子形成。结论 肾上腺非霍奇金淋巴瘤超声声像图多表现为边界清楚的规则低回声团块,肿瘤内无明显或仅见少许点状血流信号,但对于内部回声不均匀伴有液化等征象的病灶,不能完全除外淋巴瘤的可能。

Sonographic characteristics of adrenal non-hodgkin's lymphoma

Objective To investigate the sonographic characteristics of the adrenal non-hodgkin''s lymphoma. Methods Thirteen patients who were pathological diagnosed with adrenal lymphoma through biopsy or surgery were included. All the patients underwent ultrasound examination and the sonographic characteristics of the masses were retrospectively analyzed. Results Six patients manifested as bilateral adrenal masses and seven were unilateral involved, a total of 19 masses, which all were non-Hodgkin''s lymphoma diffuse large B-cell. The diameters of 19 masses were 3.0-14.0 cm, average (7.99±3.08)cm. Eighteen lesions manifested as hypoechoic masses, one lesion manifested as clutter echo. Ten masses were homogeneous, while the remaining 9 were inhomogeneous, 7 of which were accompanied with cord-like hyperechoic and 4 were accompanied with small no-echo areas. CDFI showed no obvious blood detected in 68.42% (13/19) of the masses, and 31.58% (6/19) were of poor blood flow signal. In addition, 3 bulk masses invaded ipsilateral kidney and surrounding tissues in different degrees, 1 was accompanied with the inferior vena cava embolus. Conclusion Ultrasonographic manifestations of the adrenal non-Hodgkin''s lymphoma almost presents as regular homogeneous hypoechoic masses. Little or no blood flow signal in the majority of lesions are detected, but for the inhomogeneous echogenicity lesions accompanied with liquefaction also cannot completely rule out the possibility of lymphoma.
