So many factors as for etiology of neonatal hyperbilirubinemia have been reported by many workers. However, only few regarding the role and significance of giant cephalohematoma in patients with neonatal hyperbilirubinemia were seen. It is the purpose of this paper to present the case of neonatal hyperbilirubinemia associated with giant cephalohematoma.
A three-day-old male was admitted to our hospital because of marked jaundice. At the time of admission, giant hematoma which was confirmed by X-ray and needle biopsy later was noticed on the left side of head. In spite of the through examination for jaundice including biochemical, serological and bacteriological study, no etiological factors were detected beside cephalohematoma.
Although there is a possibility for formation of bilirubin from the result of red cell destruction in the cavity of hematoma, no complete explanation for the cause of jaundice in this patient could be obtained. However, it might be suggested, at least in part, that the decrease of hemoglobin level in the hematoma corresponding the level of bilirubin concentration in the serum contribute to the cause of jaundice.
