Ischemic strokes revealing neurosyphilis: Study of six (6) observations at the neurology Department of the University Hospital of Conakry

•Stroke is a major public health problem, and the etiological aspects are poorly studied and documented because of under-medicalization.•The syphilitic etiology was confirmed in six (6) patients with a mean age of 43 years (extremes 36 and 49 years).•The clinical picture was dominated by carotid syndromes: superficial and deep sylvian syndrome, anterior cerebral artery syndrome and vertebro-basilar syndromes and one case of lacunar syndrome.•The diagnosis was based on the positivity of serological reactions (VDRL-TPHA) in blood and cerebrospinal fluid (CSF) and the presence of hypercellularity with predominantly lymphocytic pleiocytosis and hyperproteinorachy in the CSF in the absence of any other etiologies.
