MOYA MOYA, Antonio José et al. Cerebral vasculopathies due to drug abuse in adult patients: a case report. JONNPR [online]. 2020, vol.5, n.2, pp.212-217.  Epub Sep 14, 2020. ISSN 2529-850X.


Moyamoya disease is a cerebrovascular disease characterized by progressive stenosis of the arteries of the circle of Willis, conditioning the appearance of an anomalous compensatory vascular network, the moyamoya vessels. These areas are more susceptible to suffering ischemia or haemorrhage.

Case report

A 47-year-old man with symptoms of weakness in the left upper limb and clumsy walk because of left leg, of 5 days' evolution, in relation to cocaine consumption. In arteriography, extensive collateral network compatible with the moyamoya pattern.


The chronic consumption of cocaine produces abrupt increase in blood pressure, cerebral vasoconstriction, vasculitis and acute thrombosis, with the consequent development of moyamoya vessels as a compensatory physiological mechanism.

Keywords : Acquired vasculopathy; Case report; Cocaine; Drug abuse; Ictus; Moyamoya syndrome.
