腎臟為淋巴瘤常常侵犯的器官,但文獻上有關腎臟淋巴瘤(renal lymphoma)的病灶,卻多半在解剖時才發現。由於一般傳統的放射學檢查,常常無法探測出來,同時更難明確地顯示淋巴瘤對腎臟侵犯的方式和範圍,致易被遺漏了診斷。從民國73年2月至民國76年2月,我們共收集了15例腎臟淋巴瘤的病例。其在電腦斷層攝影(CT)上表現有5種不同的形態;包括(1)多結節狀(multiple nodul)佔45.8%;(2)單一結節狀(solitary nodule)佔16.7%;(3)瀰漫性浸潤(diffuse infiltration)佔12.5%;(4)直接被鄰近淋巴瘤病灶局部性侵犯(direct local Invasion)佔16.7%;(5)腎臟被後腹腔病灶整個吞噬(engulfment by retroperitoneal disease)佔8.3%。本文主要報告從腎臟淋巴瘤在CT上表現的形態,以祈瞭解淋巴瘤對腎臟侵犯的方式,以及利用CT的追蹤性檢查,來評估腎臟淋巴瘤對治療的效果。
Renal involvement by lymphoma is commonly found at autopsy but is seldom detected by conventional radiological studies. A retrospective review of 15 patients who had renal lymphoma, with a total of 24 kidneys which were evaluated by CT, presented the following five different manifestations: (a) multiple nodules in 11 kidneys, 45.8%; (b) solitary nodule in 4 kidneys, 16.7%; (c) diffuse infiltration in 3 kidneys, 12.5%; (d) direct local invasion by contiguous disease # in 4 kidneys, 16.7%; (e) engulfment by rtetroperitoneal disease in 2 kidneys, 8.3%. According to the presentations of the renal lymphoma in CT, we can evaluate the patterns of the involvement, the course of the disease and the response to the therapy of renal lymphoma.
