Benign medullary fibroma of the kidney: a rare diagnostic dilemma.

Kumar S, Choudhary GR, Nanjappa B, Bal A - J Clin Imaging Sci (2013)

Bottom Line: Renomedullary interstitial cell tumor or medullary fibroma, is a small tumor that commonly presents as an incidental finding, but in rare cases maybe large and symptomatic.Although it is a benign tumor, it is difficult to differentiate this lesion from other malignancies of the kidney on radiological basis and hence many patients undergo radical nephrectomy.We present a case of renal medullary fibroma and various nuances associated with radiological identification of this lesion and its management related dilemmas.

ABSTRACT
Renomedullary interstitial cell tumor or medullary fibroma, is a small tumor that commonly presents as an incidental finding, but in rare cases maybe large and symptomatic. Although it is a benign tumor, it is difficult to differentiate this lesion from other malignancies of the kidney on radiological basis and hence many patients undergo radical nephrectomy. We present a case of renal medullary fibroma and various nuances associated with radiological identification of this lesion and its management related dilemmas.

Figure 2: 32-year-old male with left flank pain and gross hematuria diagnosed with renal medullary fibroma. Contrast enhanced computed tomography reveals doubtful enhancement around the calcified partially exophytic mass with perirenal mild inflammatory stranding (arrow).

Mentions: Computed tomography (CT) scan of the abdomen revealed a calcified, partially exophytic soft-tissue mass involving the mid and interpolar regions of the right kidney [Figure 1]. Contrast enhanced CT revealed doubtful enhancement with perirenal mild inflammatory stranding [Figure 2]. There were no calculi either in the kidney or the ureter. There was no evidence of renal vein or venacaval extension and no obvious lymphadenopathy. The contra-lateral kidney was normal. Right renal cell carcinoma (RCC) was suspected and patient underwent laparoscopic right radical nephrectomy.
