Abstract

Introduction: Epidermoid cysts of the cerebellopontine angle (APC) are rare ‎benign tumours that generally recur after incomplete initial excision (1,3).‎

Observation: We report a case of recurrence of a right PCA epidermoid cyst in a ‎‎45-year-old patient, ten years after initial surgery. A retrosigmoid approach, using ‎neuro-navigation and facial nerve monitoring, allowed controlled subtotal resection.‎

Results: The postoperative course was uneventful, with clinical improvement and ‎no new deficits. Postoperative MRI showed a stable residue.‎

Conclusion: Surgery for recurrence of epidermoid cysts of the APC remains ‎challenging due to capsular adhesions. Careful subtotal resection avoids ‎neurological complications (3,11)‎.
