# Inflammatory myofibroblastic tumor of the right renal pelvis: A case report

## TL;DR

This case report describes a rare tumor in the kidney of a 54-year-old man, diagnosed through imaging and treated with surgery.

## Contribution

The novelty lies in reporting an inflammatory myofibroblastic tumor in the renal pelvis, a rare location for this tumor type.

## Key findings

- A mass in the right renal pelvis was identified using CT and MRI.
- The patient underwent laparoscopic radical nephroureterectomy for treatment.

## Abstract

Inflammatory myofibroblastic tumor(IMT) is an uncommon soft tissue neoplasm rarely reported in the urinary tract. A 54-year-old male presented to our institution with low back and abdominal pain, hematuria, and lower urinary tract symptoms for 2 months. We performed abdominal contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI), which showed a mass in the right renal pelvis-inferior calyx. Then, we performed the laparoscopic radical nephroureterectomy.
