PURPOSE: The aims of this study were to present an uncommon intracranial germinoma manifesting as skull base extension and analyze its clinical characteristics to give valuable insight into such uncommon radiologic variant.
METHODS: This is a clinical study of a 15-year-old girl with intracranial germinoma manifesting as skull base extension. Clinical characteristics, magnetic resonance imaging scan observations, pathologic findings, and flow of the treatment procedure were presented and analyzed.
RESULTS: She had a 5-month history of diuresis and diplopia. magnetic resonance imaging observation displayed a neoplasm located in the right-side central skull base and suprasellar area with wide extension into the cavernous sinus, intraorbital region, ethmoidal sinus, sphenoid sinus, and pituitary fossa. After administration of contrast medium, strong and heterogeneous enhancement of the mass was observed, with a dural tail sign along the right cerebellar tentorial. Right pterional approach was performed, and intraoperative histologic examination suspected the diagnosis of germinoma; partial resection was achieved, and postoperative radiotherapy was administered. Cranial nerve palsy improved greatly 6 months postoperatively.
CONCLUSIONS: Although highly unusual, germinoma should be included in the differential diagnosis of all masses with extension along the midline region of skull base, especially when it happens in young female patients.
