Cerebellopontine angle lipoma

Area of Science:

• Neurosurgery
• Neuroradiology
• Pathology

Background:

• Intracranial lipomas are rare benign tumors composed of mature adipose tissue.
• The cerebellopontine angle is an uncommon location for intracranial lipomas.
• Previous reports indicate a high incidence of symptomatic presentation due to cranial nerve compression.

Observation:

• This report details a rare case of a cerebellopontine angle lipoma.
• Clinical presentations, surgical management, and radiologic findings are discussed.
• Diagnostic challenges, including recognition of fat density on computed tomography (CT), are highlighted.

Findings:

• Lipomas in the cerebellopontine angle frequently cause symptoms by compressing adjacent cranial nerves.
• Computed tomography (CT) is crucial for diagnosis, but fat density may not always be recognized.
• Surgical management and radiologic assessment are key components in handling these rare lesions.

Implications:

• Accurate radiologic assessment, including recognition of fat density, is vital for diagnosing cerebellopontine angle lipomas.
• Understanding the clinical presentation and surgical considerations aids in managing these rare intracranial tumors.
• Further investigation into the optimal diagnostic and therapeutic strategies for these lesions is warranted.
