Summary
A rare cerebellopontine angle cavernous angioma (CA) caused hearing loss and facial weakness. Surgical biopsy confirmed CA, with slight facial improvement post-operation.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Cavernous angiomas (CA) are rare vascular malformations.
- Cerebellopontine angle (CPA) cavernous angiomas are exceptionally rare, particularly those involving cranial nerves.
Observation:
- A 60-year-old female presented with progressive sensorineural hearing loss and facial paresis.
- CT and MRI revealed a hyperintense intracanalicular lesion in the right CPA.
- Surgical exploration identified a lobulated tumor involving the 7th and 8th cranial nerves.
Findings:
- Histological examination confirmed the lesion as a cavernous angioma with multiple hematomas.
- Biopsy and hematoma evacuation were performed to preserve cranial nerve function.
- Postoperative improvement was noted in facial paresis, while hearing loss persisted.
Implications:
- This case highlights the diagnostic challenges of CPA cavernous angiomas.
- Understanding the clinical and neuroradiological features is crucial for surgical planning.
- Further analysis of reported cases aids in characterizing this rare entity.
