Dural-based infantile hemangioma of the posterior fossa: Case report.

BACKGROUND: The authors present the unique case of a dural-based, infantile hemangioma located in the posterior fossa of a 15-day-old infant.

CASE DESCRIPTION: The patient presented with hydrocephalus. The lesion was identified by magnetic resonance imaging and was subsequently resected. Diagnosis of the lesion was confirmed with immunohistochemistry staining. The patient's hospital course was complicated by transverse sinus thrombosis and a cerebrospinal fluid leak that were treated with anticoagulation therapy and ventriculoperitoneal shunt placement, respectively.

CONCLUSION: Although hemangiomas are benign entities, our patient's lesion was in the posterior fossa causing compression and hydrocephalus that necessitated resection. We encourage others to consider the possibility of hemangioma in the differential diagnosis of dural-based posterior fossa lesions in infants.
