  • Title: Solitary spinal epidural cavernous angiomas in children presenting with acute neurological symptoms caused by hemorrhage.
    Author: Sarikaya-Seiwert S, Gierga K, Wessalowski R, Steiger HJ, Hänggi D.
    Journal: J Neurosurg Pediatr; 2010 Jan; 5(1):89-93. PubMed ID: 20043742.
    Abstract:
    Spinal solitary epidural cavernous angiomas are rare benign vascular malformations, which occur even less frequently in children than in adults. It is uncommon to find such lesions without adjacent vertebral involvement. Occasionally, these lesions can lead to neurological symptoms through growth or due to intralesional hemorrhage. In this report the authors describe 2 children presenting with acute symptoms and neurological deficits caused by hemorrhage within solitary spinal epidural cavernous angiomas. A 13-year-old girl and a 9-year-old girl, previously healthy, were admitted to the authors' department due to acute radicular pain and neurological deficits. In both cases MR imaging revealed a solitary epidural mass with signs of bleeding and compression of the spinal cord. Complete resection of the lesion via a dorsal approach was performed in both patients. The histological examination of the lesions revealed the characteristic structures of a cavernous angioma with hemosiderin deposits and acute hemorrhage. Both patients recovered fully after surgical removal of the lesions. Review of the literature confirmed that spinal epidural cavernous angiomas are extremely rare in the pediatric patient population, described currently in only 2 instances, but without acute hemorrhage. These cases suggest that epidural cavernous angiomas also have to be considered in the pediatric patient population in the differential diagnosis of intraspinal lesions with acute or progressive neurological symptoms. Microsurgical resection of these cavernous malformations is an effective and curative treatment option.
