Intracerebral epidermoid tumor: a case report and review of the literature.

摘要: BACKGROUND Intracerebral epidermoid cysts are rare lesions and may account for only 1.5% of intracranial tumors. Cell entrapment from the mesectodermal origin neural crest within primitive cerebral hemisphere lead to formation such intracerebral lesions. METHODS An cyst located in right temporal lobe that was surgically treated is presented. The origin, clinical course, radiological features, surgical treatment uncommon discussed based on a review literature. RESULTS Intraoperative findings revealed an tumor. postoperative course uneventful patient discharged with no neurological deficits. On long-term follow-up (2 years), there were signs recurrence. CONCLUSIONS Truly tumors rarely found. Cells originating lines migrate remain trapped while tube closing, leading intraparenchymal Accurate preoperative diagnosis can be very difficult due similarities other common (e.g., astrocytomas or gliomas). Magnetic resonance imaging (MRI) studies, especially diffusion-weighted images, allow greater accuracy differential diagnosis. Radical removal should attempted, but less aggressive strategy considered if strong adherence between tumor capsule brain tissue, particularly eloquent areas.
