Rationale:
Cerebellopontine angle (CPA) ependymomas are atypical kind of ependymomas that characteristically occur in the pediatric age group. Therefore, finding a case of CPA ependymoma in a young male adult is not a common occurrence.
Patient Concerns:
We present a case of a 28-year-old male who was involved in road traffic accident with suspected mild head injury. He did not have any antecedent complains before the accident.
Diagnoses:
An incidental computer tomographic scan of the head revealed an intracranial space-occupying lesion at the left CPA. Immunohistochemical staining of the specimens indicated WHO grade II ependymoma.
Interventions:
The tumor was surgically resected and the patient was further treated with radiotherapy.
Outcomes:
The patient recovered well postoperatively and 2 years follow-up revealed no tumor recurrence and the patient is currently well.
Lessons:
The diagnosis of ependymomas can be very challenging in adults because they are mostly mainly seen in the pediatric age group. We propose that one of the differential diagnosis of tumors in the CPA in a young adult should be CPA ependymoma.
