Summary
A large cerebellopontine angle lipoma caused hearing loss and trigeminal neuralgia. Surgical debulking relieved symptoms, demonstrating a minimally invasive approach for cerebellopontine angle tumors.
Area of Science:
- Neurosurgery
- Neurology
- Oncology
Background:
- Cerebellopontine angle (CPA) lipomas are rare, benign tumors often presenting with cranial nerve deficits.
- Large CPA lipomas can cause significant neurological symptoms due to mass effect.
Observation:
- A 46-year-old male presented with a large left CPA lipoma.
- Symptoms included ipsilateral hearing loss and trigeminal neuralgia, exacerbated by posture.
Findings:
- Surgical intervention involved debridement of arachnoid membranes to reduce tumor tension.
- This minimally invasive approach led to stable remission of pain and hearing improvement.
Implications:
- Simple debulking can be an effective treatment for symptomatic CPA lipomas.
- Preserving neurological function is achievable with tailored surgical strategies for CPA tumors.
