Background Subependymomas are uncommonly encountered ependymal tumors, accounting for less than 1% of all intracranial neoplasms and distinguished from ordinary ependymomas because of their generally better prognosis. Here we present a case of subependymoma with rare clinical presentation. Case presentation 19 year old male student presented to us with complaints of persistent left sided pain and numbness for one month duration following herpes zoster over left face. Clinical examination was normal except decreased perception of pain and touch on the whole left side of the body. MRI with gadolinium of the brain revealed a posterior fossa mass almost occluding the fourth ventricle with infiltration to the right side immediately behind the pontine tegmentum probably impinging on the right spinothalamic tract causing the patient symptoms. Post operative tumor histopathology revealed the classical appearance of subependymoma with characteristic clusters of nuclei in a dense fibrillary background. Conclusion Post operatively patient remained pain free at six month follow up. Supependymoma is generally asymptomatic. In this patient whole left sided dysesthesia raised the suspicion of central pathology than unlikely post herpetic etiology. This case is reported for the interesting atypical presentation and the importance of diagnosing benign tumor which can change the prognosis.
