Cerebral Hemorrhage following Aspirin Administration in a Patient with Delayed Diagnosis of Kawasaki Disease

Abstract

Background: Kawasaki disease (KD) is an acute vasculitis of childhood, which has a typical coronary artery aneurysm complication. Cerebral arteries are usually spared from the disease process. Intracranial aneurysms and hemorrhage strokes are rarely reported.Case presentation: A 12-year-old boy presented with a sudden disturbance of consciousness caused by an intracranial aneurysm’s rupture. Through later clinical manifestations and echocardiography, we found that he had been in Kawasaki disease 20 days before the hospitalization.Conclusions: This case shows a close link between Kawasaki disease and cerebral aneurysm complication. It arouses more attention to applying aspirin appropriately in the perioperative intracranial surgery period of KD patients. For febrile patients with high-risk factors for KD, echocardiograms may be performed before day 5 of fever.
