A Unique Case of Intracranial Bifocal Germinoma

Primary intracranial germ cell tumors are rare tumors that often occur in children and young adults. We report a case of a 17-year-old male, who presented with vomiting, headache, and blurring of vision of the left eye on the temporal aspect for two months. His biological assessment showed panhypopituitarism. Serum markers showed elevated beta human chorionic gonadotropin and lactate dehydrogenase. A solid cystic lesion was noted on imaging, involving the sella, parasellar region, and pineal region with calcifications within. Diagnosis of bifocal germinoma was confirmed by tumor biopsy. The treatment protocol for the patient involved four cycles of chemotherapy using etoposide and carboplatin, followed by a course of radiotherapy.
