# Pulmonary Calcifying Fibrous Tumor in a Pediatric Patient: A Case Report

## TL;DR

A rare case of a non-cancerous lung tumor in a 9-year-old boy is reported, highlighting diagnostic challenges and imaging findings.

## Contribution

This paper provides a detailed case report of a rare pulmonary calcifying fibrous tumor in a pediatric patient.

## Key findings

- Pulmonary calcifying fibrous tumor is extremely rare and often misdiagnosed initially.
- Computed tomography and magnetic resonance imaging provided key diagnostic insights in this case.

## Abstract

A calcifying fibrous tumor (CFT), also known as calcifying fibrous pseudotumor, is an uncommon non-cancerous neoplasm usually located in the gastrointestinal tract. Its location in the lung is extremely rare, and only a few case reports have been published. This case report describes our diagnostic approach in a 9-year-old male patient with an incidental pulmonary mass. The mass was initially misdiagnosed, requiring multiple imaging tests and interventions to obtain the definitive diagnosis of pulmonary CFT. This paper aims to contribute to the limited information available on pulmonary CFT by presenting detailed findings from computed tomography and magnetic resonance imaging.
