ABSTRACT

We experienced a case of metastatic intracranial dysgerminoma on the midline of the parieto-occipital bone and epidural space involving the posterior fossa, which was early metastasis intracranially. A 17 years old female had been admitted because of protruded mass on the midline of the parieto-occipital region for about 1 year, sudden severe headache, vomiting, and drowsy state. Simple skull x-ray films had revealed hyperostosis with sun burst appearance, and vertebral angiography had showed a well visualized posterior meningeal artery, which had been outlined the epidural mass on the parieto-occipital region invading posterior fossa. Brain C.T. had revealed isodensity in preinfusion state, but increased density on enhancement. We had operated the tumor by conventional craniectomy, and radiotherapy had been followed on the craniocervical region. The radiotherapy had been very effective. Biopsy from the intracranial tumor had revealed a germinoma. But about 10 month later following discharge from the hospital, the patient had a huge abdominal mass, and the mass revealed an ovarian dysgerminoma microscopically, which was identified the same structure as germinoma had. We concluded that the tumor mass was metastatic intracranial dysgerminoma from the ovarian dysgerminoma in the case.
