Atypical Kawasaki Disease Presenting with Hemiparesis and Aphasia: A Case Report

Ali Nikkhah

Abstract


Kawasaki disease (KD) is an inflammatory vasculitis. KD is classified into two groups based on clinical characteristics criteria, namely classic and incomplete. Cerebral vascular abnormality, especially arterial ischemic stroke (AIS) is very rare and unusual in KD. Here, we report a 4-year-old boy who was referred to our tertiary pediatric center with abrupt right hemiparesis and aphasia. At admission time, he had febrile illness and was toxic. On physical examination, we found unilateral left submandibular lymphadenopathy. On neurologic examination, we obtained right sided hemiparesis with hemiparetic gait and aphasia. His deep tendon reflexes (DTRs) of right extremities were exaggerated and his sensory system was intact. Based on these features, some differential diagnoses were suggested, such as acute encephalitis with focal signs, brain abscess, cerebral vasculitis, hemorrhagic insults, and ischemic stroke, etc. After a complete evaluation, especially brain MRI and MRA, our diagnosis was arterial ischemic stroke (AIS) following atypical KD. Based on these findings, we administered intravenous immunoglobulin (IVIG 2 gm/kg) and oral high dose aspirin (100 mg/kg/d). He responded to these anti-inflammatory treatments dramatically.
