医学影像英语每日读丨153.Renal Lymphoma

领读：  妙然老师

Renal lymphoma

Lymphoma usually involves the kidney in a recognizable pattern. The most common manifestation of renal lymphoma is multiple masses, and most often affects both kidneys. This pattern (multiple masses) occurs in 40% to 60% of cases.

A second pattern of renal lymphoma is perirenal disease. Although the perirenal pattern is only seen in 10% of renal lymphoma cases, the imaging appearance is virtually pathognomonic. 

In addition, renal lymphoma is considered the most common perirenal mass. A key point to recognize is that lymphomatous masses are mostly homogeneous and routinely enhance less than normal renal parenchyma. Additional clues for diagnosing lymphoma can be key for clinching the diagnosis, such as retroperitoneal adenopathy or splenomegaly.

【Renal lymphoma 肾脏淋巴瘤】 淋巴瘤累及肾脏是一种常见的类型。最常见的征象为多发肿块，通常双肾受累。这种类型（多发肿块型）约占40-60%。 另一种类型为肾周型。仅占肾淋巴瘤的10%。影像表现具有特征性，可以确诊。 此外，肾淋巴瘤是肾周肿块最常见的原因。鉴别淋巴瘤肿块的关键在于，大多数肿块强化程度均匀一致，低于正常肾实质。其他的一些伴随征象也有助于诊断淋巴瘤，比如腹膜后淋巴结肿大、脾大。
