Extramedullary intradural capillary hemangioma in a patient of 03 months of life: a case report

Abstract

Introduction: Capillary hemangioma is an extremely rare endothelial cell neoplasm as an extramedullary intradural tumor. Its presentation in infants is anecdotal and only 2 cases have been previously reported in the literature. Clinical case: a 03-month-old infant with severe abrupt-onset paraparesis. Spinal magnetic resonance imaging (MRI) showed an intraspinal tumor at the T7, T8, and T9 levels, which captures contrast. A T7-T9 laminectomy and microsurgical resection of the extramedullary spinal tumor were performed. The pathology was reported as lobulated angiomatous proliferation with focal vascular thrombus, with positive immunohistochemistry for CD 31 and 34, compatible with capillary hemangioma. The neurological evolution was favorable. Post-surgical MRI and spinal angiography showed little residual tumor and hydrosyringomyelia in remission. Conclusion: Capillary hemangioma is a rare pathology in infants, this case being the 3rd case reported. Its diagnosis and surgical resection are important since most patients present an improvement in the neurological deficit after surgery. Surgical treatment avoids the risk of acute bleeding Keywords: Hemangioma, Capillary, Spinal Cord Neoplasms, Infant, Laminectomy. (Source: MeSH NLM)
