1、 Case discussion by abdomen group2012-3-14HistoryFemale 63yget wound in a fall 1 month agoUSG:solid mass lesion of left kidneySPECT:high perfusion in the mass lesion of left kidney Cortical period(CT value: 110HU;36HU)Medulla period(CT value:180HU;62HU)Discharge period(CT value:107HU;57HU)VROperatio
2、n: left kidney radical correction Pathology : Renal oncocytomaDDXRenal oncocytoma ,RORenal oncocytomaRenal oncocytomas are benign,rare, solid tumours of the kidney,derived renal cortex epithelium of proximal convoluted tubule.,comprising 37% of all renal tumors Occur in all ages, the most in about 5
3、0y,generally men more than women ,M:F 1. 51. 7 :1Most is solitary ,can also be complicated with Polycystic kidney , renal angiomyolipomas , renal cancer usually asymptomatic and discovered incidentallyRenal oncocytomaCT scannerA well-defined marginCentral stellate scar d 100HU, CT value fell rapidly
4、 in the medulla period, “Quick in quick out”Renal chromophobe cell carcinoma(RCCC)Diagnostic pointLocated in the medullary , expansion growth to renal sinus and renal cortical , tumor size larger , on the surrounding renal organization performance for the only signs of oppression Enhanced scanning:
5、Light to moderate , homogeneous strengthening of the tumor, change of density is not obvious in each period, And there is no clinical symptoms and transfer of the patients RCCC can also see scar, but less than the RO Cystic or necrosis rarelyIdentify points:The enhanced, almost the strengthening of the RO significantly higher than RCCC , but sometimes RO and RCCC performance has across, therefore need to pathological diagnosisThank you!
