目的探讨肾脏继发性淋巴瘤的CT表现,以提高对该病的认识和诊断能力。方法回顾性分析7例肾脏继发性淋巴瘤患者的资料,均为非霍奇金淋巴瘤。所有病例均行腹部CT平扫+增强扫描。结果 7例肾脏继发性淋巴瘤,5例为结节(肿块)型,其中多发2例,单发3例,邻近病灶侵犯型1例,肾周淋巴瘤1例,病灶直径从数毫米至7.2 cm。CT平扫所有病变密度均匀,其中4例为等密度,3例为稍高密度,平扫CT值30.6～38.3 HU(平均34.6 HU);增强动脉期CT值42.7～65.7 HU(平均49.7 HU),静脉期CT值50.5～86.5 HU(平均64.1 HU),平衡期CT值55.3～115.2 HU(平均71.3 HU),3例中度均匀延迟强化,4例明显均匀延迟强化。结论肾脏继发性淋巴瘤的CT表现形式多样,密度均匀,增强扫描呈进行性延迟强化,平衡期扫描有助于提高小病灶的发现率,明确诊断需要结合临床资料。
Objective To explore the CT manifestations of renal secondary lymphoma in order to improve the understanding and diagnosis of the disease. Methods Retrospective analysis of 7 cases of renal secondary lymphoma patients, all non-Hodgkin’s lymphoma. All cases underwent abdominal CT scan + enhanced scan. Results 7 cases of secondary renal lymphoma and 5 cases of nodules (mass) type, including 2 cases of multiple, single in 3 cases, 1 case of adjacent lesions violations, 1 cases of perirenal lymphoma, lesion diameter from a few millimeters to 7.2 cm. All lesions were uniform in CT scan, of which 4 had isodense density, 3 had slightly higher density, 30.6 ~ 38.3 HU (average 34.6 HU) under CT scan, 42.7 ~ 65.7 HU (average 49.7 HU) at arterial phase, , Venous phase CT value 50.5 ~ 86.5 HU (average 64.1 HU), balance period CT value 55.3 ~ 115.2 HU (average 71.3 HU), 3 cases of moderate uniform delay enhancement and 4 cases of obvious uniform delay enhancement. Conclusions CT manifestations of renal secondary lymphoma are diverse, with uniform density and enhanced scan with progressive delayed enhancement. The balance period scan can help to improve the detection rate of small lesions. A clear diagnosis needs to be combined with clinical data.
