Cerebellopontine angle subependymoma without fourth ventricle extension: An uncommon tumor in a rare location

Subependymomas are benign tumors that occur predominantly in the ventricular system. We describe a case of a 57‐year‐old man with a large cerebellopontine angle (CPA) tumor which expanded into the jugular foramen. Complete surgical excision of the tumor was achieved through a retrosigmoid approach a...

Zusammenfassung:Subependymomas are benign tumors that occur predominantly in the ventricular system. We describe a case of a 57‐year‐old man with a large cerebellopontine angle (CPA) tumor which expanded into the jugular foramen. Complete surgical excision of the tumor was achieved through a retrosigmoid approach and the histopathological diagnosis was subependymoma. Subependymomas located exclusively in the CPA without extension into the fourth ventricle are extremely rare. The mainly pathological features and the difficulty in correctly diagnosing these cases preoperatively, even with MRI, are discussed.
