title: Pontine extraventricular neurocytoma in a child.
abstract: Extraventricular neurocytomas mimic central neurocytomas histologically but are located outside the lateral and/or third ventricles. Pontine neurocytomas represent an extremely rare subset of extraventricular neurocytomas, and reports are limited to 2 adults followed under 28 months. The authors present the case of a 14-year-old boy who initially underwent near-total resection of a pontine extraventricular neurocytoma. One-year postoperative surveillance imaging revealed a small, local recurrence treated with intensity-modulated radiation therapy. This case details the diagnosis and management of the first reported pontine extraventricular neurocytoma in a child with 4.5-year follow-up data.
