title: Congenital supratentorial cystic hemangioblastoma. Case report and review of the literature.
abstract: Supratentorial hemangioblastomas are rarely encountered tumors even in the pediatric population; an extensive review of the literature has revealed approximately 118 cases. However, only five of these occurred in infants, and three occurred during the first 2 months of life. A 5-week-old boy presented with emesis, irritability, a bulging anterior fontanelle, and a head circumference that had gradually expanded since birth. His medical and family histories were uninformative in terms of cancer or inherited diseases. Magnetic resonance imaging demonstrated a large loculated cyst with a heterogeneous contrast-enhancing 3-cm nodule, first pushing the left frontal and parietal lobes and then displacing into this region. After being exposed via a left frontoparietal craniotomy, the cyst was evacuated by a soft drain, and then the mass was totally excised. The histopathological diagnosis was a reticular variant of hemangioblastoma. Given that von Hippel-Lindau (VHL) gene mutations may be associated with hemangioblastomas, sequencing analysis of the VHL gene was performed; sequencing of the three exons of the VHL gene showed no exonic mutations. Clinical and neuroimaging follow-up of the patient have revealed an improved health status during the last 23 months. The authors reviewed the literature concerning congenital supratentorial hemangioblastomas, and they discuss the clinical and histopathological characteristics and differential diagnosis associated with such lesions.
