Minor stroke and major vascular occlusion. A case report.
Occlusion of middle cerebral artery (MCA) is generally associated to severe stroke and poor prognosis; however a few patients with mild to moderate presentation and long-term reversibility of neurological deficits have been reported. A 66-year-old male presented with left-side weakness and dysarthria (NIHSS score 7), which progressively resolved within a few days; ischaemic lesion of the anterior arm of the right internal capsule was found at brain CT obtained 72 h after presentation. Transcranial Colour Doppler showed absence of flow of the right MCA. Cerebral angiography showed occlusion of the right MCA that was retrogradely revascularised by leptomeningeal collaterals. Non-invasive intracranial vascular examinations could identify major intracranial artery lesions in patients who present with mild to moderate stroke symptoms. These patients could be identified and followed to clarify their best treatment and prognosis.
