Diffusion Weighted MRI – The Diagnostic Modality to Differentiate Renal Pseudotumor from Renal Cell Carcinoma in Chronic Kidney Disease: A Case Report
Diffusion Weighted MRI
Renal pseudo tumors are rare occurence in patients with chronic kidney disease, most of the times it is detected incidentally on imaging and mimics a renal cell carcinoma. It is imperative to exclude renal cell carcinoma in these patients. A 38-year-old female P2L2A0 presented with menorrhagia, Blood laboratory test revealed elevated creatinine level 2.2 mg/dl. Other blood parameters showed raised urea levels -52, urine protein to creatinine-1.3 and urine protein 1+. Follow up lab values for a period of 3 months revealed persistently raised urea and creatinine levels. MRI with contrast demonstrates small sized bilateral kidneys with parenchymal thinning and multiple well defined lobulated partially exophytic mass lesions, homogenously mildly hyperintense on T2W images, and isointense on T1W images, lesion demonstrated no diffusion restriction on DWI images.
