Utility of cone beam computed tomography for rare temporal bone lesion: A case report

TL;DR

A 63-year-old woman's rare temporal bone lesion was accurately diagnosed using cone beam computed tomography, which offered better resolution and less radiation than traditional methods.

Contribution

The paper demonstrates the diagnostic utility of cone beam computed tomography for rare temporal bone lesions.

Findings

Cone beam computed tomography provided a definitive diagnosis of temporal bone exostosis.

Traditional imaging methods like CT and MRI were inconclusive in identifying the lesion.

Cone beam CT offers superior spatial resolution and lower radiation exposure for such cases.

Abstract

This case report aims to describe the clinical presentation, imaging findings, diagnostic challenges, and management of a patient with a cerebellopontine angle lesion. A 63-year-old woman presented with progressive headaches, tinnitus, right ear pressure, and dizziness. Initial imaging studies (computed tomography and magnetic resonance imaging) suggested either a thrombosed aneurysm or a lipoma. However, advanced imaging with cone beam computed tomography provided a definitive diagnosis of temporal bone exostosis. This case highlights the importance of cone beam computed tomography in diagnosing complex intracranial lesions due to its superior spatial resolution and lower radiation dose.
