    Abstract:
    Although arteriovenous malformation (AVM) is considered a congenital disease, few cases of AVM are manifested clinically in the neonatal period. In this paper a neonatal case of AVM manifested as intracranial hemorrhage is reported. A newborn female infant 12 days after birth, was admitted to a hospital with the chief complaint of sudden onset of vomiting and fever. Neurological examination revealed left hemiparesis with bulging of the anterior fontanel. CT examination demonstrated a large mass lesion with hemorrhage in the right parietal lobe. The lesion was enhanced with contrast medium. Consent for surgery was not able to be obtained from her family, so she was treated conservatively. A gradually enlarging cyst surrounding the mass appeared in follow-up CT examination. Her left hemiparesis and bulging of the anterior fontanel remained unchanged, and a rather good general health condition was maintained. Consent for surgery was finally obtained from her parents and the patient was transferred to our hospital three months after the onset of the symptoms. Cerebral angiogram showed AVM with a big aneurysmal sac. The feeder arteries of the AVM arose from the right middle cerebral artery and the anterior cerebral artery. The drainers poured into the superior sagittal sinus. AVM was removed totally by right parietal craniotomy on the 24th January, 1989. Postoperatively, her left hemiparesis started to improve gradually. Her general condition was also good, and she showed no neurological deficits at the age of 8 months.(ABSTRACT TRUNCATED AT 250 WORDS)
