중두개저에 발생된 성숙 기형종

Abstract

A case of intracranial mature teratoma found in a 35-year-old man is reported. This tumor was originated from the left middle cranial fossa. The tumor was exceptionally huge and MRI showed whirling appearance of intratumoral content. It seems that the temporal location permitted the tumor to grow into a huge size for a long time giving it a whirling appearance of the intratumoral content Histopathological findings were differentiated squamous epithelium. sebaceous glands. bony spicules. and neuroepithelial tissue. which were compatible with histologic findings of teratoma. It is very unusual for a teratoma to occur in the middle cranial fossa. whereas most of the teratomas are located in the midline structures. such as the pineal or the suprasellar region.
