[Intracranial extradural liposarcoma in the posterior fossa--a case report (author's transl)]

Abstract

A case of liposarcoma, which originated primarily in the left infraauricular area and infiltrated to the posterior fossa, was reported. The patient was a 25-year-old housewife, who was admitted because of symptoms of intracranial hypertension. She showed left facial palsy and deviation of the tongue to the left without any cerebellar signs. Neurological examinations suggested a mass lesion in the posterior fossa. Suboccipital craniectomy was performed and the tumor sized 4 X 4 X 3 cm in the extradural space was partially removed. Microscopically, the tumor consisted of lipoblasts and diagnosed as liposarcoma. Intracranial liposarcoma, whether primary or secondary, is very rare and only several cases have been reported.
