RAMIREZ-MORENO, J.M. et al. Isolated mesencephalic stroke related to a ruptured intracranial dermoid cyst. []. , 20, 3, pp.272-277. ISSN 1130-1473.
Dermoids cysts are embrionary benign lesions that comprise approximately 0.04-0.25% of all intracranial tumors. Occasionally they break and spread their content into subarachnoid space and/or lateral ventricles causing several acute or delayed symptoms. Debut of this type of tumor as acute stroke is poorly reflected in literature. We present a 26-year-old woman with a isolated mesencephalic infarct secondary to spontaneous rupture of a dermoid cyst. We discuss the possible pathophysiological mechanisms for this condition and review the literature.
