| Abstract: | Primary intracranial germinomas are rare tumors, accounting for approximately 1–4% of all intracranial tumors. Intracranial germinomas are more commonly found in the suprasellar and pineal midline structures of the brain. Brainstem and posterior fossa germinomas are rarer still, with few reported cases in the literature, and little discussion of their presentation, management and clinical outcome. A unique case of pontomedullary germinoma, diagnosed in a 12-year-old boy, is described. Only six previous cases of lower brainstem germinoma have been reported, with varying modes of presentation and a lack of definitive management guidelines. Of these, all occurred in either females or a patient with Klinefelter’s syndrome. We report the first case of a lower brainstem germinoma in a male without known genetic abnormality. Tumor remission was achieved with partial surgical resection, chemotherapy and radiotherapy. |
