Abstract
|
|
|
Intracranial germ cell tumors are rare lesions that account for 0.3 to 3.4% of all intracranial tumors. Although pure
forms are rare, intracranial germ cell tumors are classified into five types：germinomas, teratomas, embryonal carcinomas, endodermal sinus tumors and choriocarcinomas. Teratomas are embryonal neoplasms composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm. They may be solid or cystic and are
classified histologically as mature, immature, and malignant. Intracranial teratomas have a predilection for the supratentorial and midline sites, especially pineal area. These are arise commonly in the neonatal period. Advances in
neuroradiology and microsurgical techniques now make early diagnosis and successful treatment in many of these
patients.
We present a rare case of malignant teratoma in suprasellar region of a young boy. A complete excision of the tumor was
achieved by pterional approach. Histological diagnosis of the tumor was teratoma with malignant components.
The management, pathologic feature and clinical course of this unusual malignancy are discussed with a review of
the literatures.
