# CT and MRI Findings of Renal Angiomyolipoma With Lung Metastasis: A Case Report and Literature Review

## TL;DR

This case report presents a rare instance of kidney tumor with lung spread, using both CT and MRI for diagnosis.

## Contribution

First reported case combining CT and MRI for diagnosing renal angiomyolipoma with lung metastasis.

## Key findings

- Renal epithelioid angiomyolipoma with lung metastasis was diagnosed using CT and MRI.
- Combining CT and MRI provides a novel approach for diagnosing this rare condition.

## Abstract

Renal angiomyolipoma has two histological variants: classical and epithelioid. Epithelioid angiomyolipoma is considered as a potential malignant tumor, often leading to recurrence and metastasis, with rapid progression in most of the cases. The lung is one of the most commonly reported sites of metastasis, and pulmonary metastasis of renal angiomyolipoma is usually diagnostic by computed tomography (CT) scans. Here, we report for the first time renal angiomyolipoma with lung metastasis by combining CT and magnetic resonance imaging (MRI).
