1Department of Neurology.
Rationale:
Intracranial small aneurysm is a rare cause of ischemic stroke, and been described only in sparse case reports. The exact pathophysiology, treatment strategies, and prognosis remain incompletely understood.
Patient Concerns:
A 42-year-old man presented with an acute onset weakness of the right limbs.
Diagnoses:
Neuroimaging evaluation confirmed a diagnosis of acute ischemic stroke and left internal carotid artery (ICA) small aneurysm.
Interventions:
The patient underwent oral anti-platelet therapy (100 mg aspirin daily).
Outcomes:
The patient recovered to normal status within 4 weeks following antiplatelet treatment. During a follow-up period of 1 year, he remained neurologically asymptomatic and led a virtually normal life.
Lessons:
It is crucial for clinicians to be aware of this entity, as cerebral infarction caused by small cerebral aneurysm is extremely rare.
