Acute hemiplegia in one infant.

A previously healthy 9-month-old girl, obese (12,500 gm) with sudden onset of hyperthermia (40 degrees C), generalized tonic-clonic seizures, followed by focal seizures, drowsiness, left facial nerve palsy, left lagophthalmos and mydriasis is presented. CT-scan and MRI suggested temporal-parietal infarction due to Sylvian artery occlusion in a 9-month-old infant with familial hypercholesterolemia (type 2 A dyslipidemia). The possibility of a cerebral abscess or herpetic encephalitis was considered. Negative clinic and serologic results excluded this diagnosis. The management of the symptomatology was made with parenteral antibiotics, anticonvulsive and antioedematous cerebral therapy. Favourable evolution with residual left hemiparesis after 30 days, when the child was discharged. CT-scan reevaluation (after 5 months of evolution) showed a hypodense temporal-parietal area abnormality due to a right ischemic infarction.
