【摘要】 报道７例非肿瘤性肾脏占位图象，全部经手术探查确诊。除２例肾皮质脓肿者外，另５例均不需手术治疗。其中３例肾实质局灶性炎性浸润，ＣＴ图象酷似肾癌，但肿块边界不清或不规则，且３例都有肾结石病史。提出有肾结石史者在Ｂ超、ＣＴ发现肾脏占位病变时，应随诊观察，近期ＣＴ图象有明确消退变形可排除肾癌时，则毋需手术探查。２例肾皮质脓肿都有高热、脊肋角叩痛，ＣＴ图象肿块内部明显不均匀，可有液化区，边界不规则。肾囊肿出血及表浅肾囊肿破裂所致的纤维增生，ＣＴ图象均呈良性病变。提出，临床医师需熟悉图象诊断，并需结合临床综合考虑。更多还原

【Abstract】 cases of atypical space-occupying images of kidney, difficult to be diagnosed, were reported, the final diagnosis being established on open operation in all.5 of the 7 were focal infection of the kidney 3 of which were focal inflammatory infiltration of renal parenchyma induced by renal stone and the other 2 were cortical abcess of kidney with high fever and tenderness over the costovertebral angle. 2 sabcapsular masses were both relevant to a superficial renal cyst. In one of which,there was subcapsular infiltration of fibrous tissue induced by the rupture of a superficial renal cyst and the other was a high density renal cyst caused by intracystic hemorrhage. With wide application of B-ultrasonography and CT scanning in clinical practice and in regular physical check up, atypical space-occupying images of kidney would be met with at times becoming a new challenge to the clinicians.更多还原
