title: Parapelvic solitary neurofibroma of the kidney.
abstract: A middle-aged man presented with intermittent gross haematuria and dull aching left flank pain for 1 month. He was a chronic smoker for 15 years. Contrast-enhanced CT scan of the abdomen detected a 4.5×3.0×2.5 cm, heterogeneous and poorly contrast-enhancing mass in the left renal sinus and upper ureteric region causing narrowing of the pelviureteric junction and upper ureter. Considering it to be a transitional cell carcinoma of upper urinary tract, the patient underwent laparoscopic radical nephroureterectomy. Histopathology revealed the mass to be a neurofibroma in the renal sinus extending around the upper ureter.
