Abstract

Background Hemangiomas are congenital vascular malformations pathologically considered as harmatomas and classified as capillary, cavernous, arteriovenous or venous, and usually located at soft tissue or bone, mainly in the spinal column. Pure epidural capillary hemangiomas are extremely rare lesions that should be included in the differential diagnosis of spinal epidural lesions; only three patients with epidural capillary hemangiomas have been reported to date.

Case Report We report a case of a 57-year-old man that complained of dorsal and back pain. The neurological examination revealed back tenderness and crural paraparesis. His reflexes were exaggerated and Babinski sign was present on both sides. A magnetic resonance imaging showed an epidural lesion at the level of T10–12 that demonstrated extension with intense postgadolinium enhancement. These lesions were different from more common lesions, mainly schwanommas, mainly due to the foraminal extension, which sets them apart from cavernous hemangiomas. The surgical ressection was performed. After laminectomy, a reddish epidural mass that extended into the right T11–12 foramina was revealed. The feeding vessels had to be identified and divided. In such cases, the surgeon must carefully dissect the lesion circumferentially away from the dura and employ judicious hemostasis. The patient́s histopathological examination revealed a vascular tumor composed of vessels of several calibers. The imagery obtained from the exams led to the diagnosis of a capillary hemangioma.

Conclusions Pure epidural capillary hemangiomas should be included in the differential diagnosis of spinal epidural lesions, mainly schwanommas, especially due to the foraminal extension, which may differentiates them from cavernous hemangiomas. Surgical excision is mandatory and intervertebral foraminal extension may preclude gross total resection.

Resumo

Introdução Os hemangiomas são malformações vasculares congênitas patologicamente consideradas como hamartomas. Podem ser classificadas como capilar, cavernoso, arteriovenoso ou venoso, e são geralmente localizadas em tecidos moles ou ossos, principalmente na coluna vertebral. Hemangioma capilar epidural puro é uma lesão extremamente rara que deve ser incluída no diagnóstico diferencial das lesões espinais epidurais, foram relatados casos de apenas três pacientes com hemangiomas capilares epidurais.

Relato de Caso Relatamos o caso de um homem de 57 anos de idade com queixa de dorsalgia. Ao exame neurológico, paraparesia crural, com hiperreflexia e sinal de Babinski bilateral. A ressonância magnética mostrou uma lesão epidural no nível de T10–12 com intenso realce pós-gadolíneo. Hemangioma capilar deve ser diferenciado de lesões mais comuns, principalmente schwannomas, devido à extensão foraminal. A ressecção cirúrgica foi realizada. Um processo expansivo epidural avermelhado, se estendendo para o forâmen direito de T11–12, tornou-se evidente após a laminectomia. Os vasos que o irrigavam foram identificados e adequadamente separados. A lesão foi cuidadosamente dissecada circunferencialmente e uma hemostasia criteriosa foi realizada. O exame histopatológico revelou um tumor vascular composto por vasos de vários calibres. Exames de imagem corroboraram com a hipótese de um hemangioma capilar.

Conclusões Hemangiomas capilares epidurais puros devem ser incluídos no diagnóstico diferencial das lesões da coluna vertebral epidural, principalmente schwanommas, especialmente devido à extensão foraminal. A excisão cirúrgica é obrigatória e a extensão para o forame intervertebral pode impossibilitar a ressecção total.
