STROKE RELATED TO A DERMOID CYST - CASE-REPORT

OBJECTIVE AND IMPORTANCE: We report the case of a woman presenting wit h sudden neurological deficit, revealing a parasellar dermoid cyst. To our knowledge, this clinicopathological finding is the first reported in the literature. CLINICAL PRESENTATION: A neurological examination of the patient revealed a left hemiparesis, including central facial p alsy, which hampered her speech, The well-documented neuroradiological work-up (including computed tomography, magnetic resonance imaging, a nd magnetic resonance angiography) demonstrated right frontorolandic i schemia caused by a right supra-and parasellar dermoid cyst leading to middle and anterior cerebral arterial stenoses, INTERVENTION: Surgica l intervention, using a right subfrontopterional approach, was success ful. Complete dermoid cyst removal was achieved. The mechanism of the arterial stenoses is extensively discussed and is thought to result fr om an inflammatory reaction of the basal vessels, CONCLUSION: The pati ent recovered fully. Nevertheless, postoperative magnetic resonance im aging confirmed cerebral infarction.
