# Lipoma Arising in the Eustachian Tube

## TL;DR

A rare case of a lipoma in the eustachian tube is reported, highlighting its diagnosis and treatment.

## Contribution

This paper presents a rare clinical case of a lipoma in the eustachian tube and discusses its diagnosis and surgical removal.

## Key findings

- A 62-year-old female was diagnosed with a lipoma in the eustachian tube using nasal endoscopy and MRI.
- The tumor was successfully removed via a transnasal endoscopic approach.
- MRI is particularly useful for diagnosing lipomas in the eustachian tube.

## Abstract

Lipomas are among the most common soft tissue tumors. Surgical removal of lipoma is considered if the patient has symptoms or cosmetic challenges. Lipomas that develop from any fat tissue in the body and involve the eustachian tube are extremely rare.

Herein, we report the case of a patient with a lipoma arising in the eustachian tube. We also summarized the literature on tumors originating from the eustachian tubes.

A 62-year-old female presented to our department with a five-year history of left nasal congestion. Nasal endoscopy revealed a tumor in the left eustachian tube. The tumor was considered a lipoma on computed tomography (CT) and magnetic resonance imaging (MRI) and was removed using a transnasal endoscopic approach.

Nasal endoscopy and radiologic imaging can be used to detect tumors in the nasopharynx, including the eustachian tubes. Magnetic resonance imaging is particularly useful for the diagnosis of lipomas. A lipoma in the eustachian tube can cause nasal congestion and aural fullness, and the transnasal endoscopic approach is useful for tumor removal.
