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.

Introduction
Capillary hemangioma, also known as “Infantile hemangioma,” appears as a raised red lumpy lesion occurring anywhere on the body, although 83% are located in the head or neck area.[1] [2] [3] [4] [5] [6] Most of the epidural hemangiomas described in the literature were cavernous hemangiomas.[1] [2] [7] Epidural capillary hemangiomas are exceedingly rare lesions. Thus far, only three cases have been reported.[4] [7] We describe an additional case of a purely epidural capillary hemangioma and discuss its clinical, radiological, therapeutic, and prognostic features.

Case Report
A 57-year-old man complained of dorsal and back pain. Two months prior, he had noticed progressive difficulty walking and numbness in his legs. Neurological examination revealed back tenderness and crural paraparesis. His reflexes were exaggerated and Babinski sign was present on both sides. Urine and stool incontinence were absent.
A magnetic resonance imaging (MRI) of the thoracolumbar spine showed an epidural lesion at the level of T7–8 that extended into the right neuroforamina, as well as intense postgadolinium enhancement ([Figs. 1] and [2]). Signal flow voids could be seen on T2, indicating that the lesion was probably highly vascular ([Fig. 2]). There was significant cord compression; however, the cord signal was normal.

He underwent a T6–8 laminectomy, bilaterally. Radioscopy was used to identify the level to be approached. Electrophysiological monitoring was employed to minimize the risks of neurological worsening. After laminectomy, a reddish epidural mass that extended into the right T7–8 foramina was revealed. We noticed two feeding vessels in its superolateral aspect, which we dissected and coagulated. They were soft upon manipulation and we completely resected after circumferential dissection. Then, we removed the foraminal extension. The postoperative period was uneventful and the patient was discharged with no additional neurological deficits.
Histopathological examination revealed a vascular tumor composed of vessels of several calibers. Endothelium lined the walls. We did not observe smooth muscles and saw fibrous septa between the vessels. This image diagnosed a capillary hemangioma ([Fig. 3]).

Discussion
Hemangiomas are congenital vascular malformations pathologically considered as hamartomas and classified as capillary, cavernous, arteriovenous or venous, and usually located at soft tissue or bone, mainly in the spinal column.[2] [3] [7] [8] [9] Vertebral hemangiomas are common, however purely epidural hemangiomas constitute rare findings.[10] [11] Although cases of purely epidural cavernous hemangiomas have been described, thus far, only three patients with epidural capillary hemangiomas have been reported.[2] [4] [5]
Differential diagnosis of epidural lesions includes nerve sheath tumors, meningiomas, hemangiopericytomas, hemangioblastomas, cavernous hemangiomas, and lymphomas.[7] [11] [12] [13] A constant feature of the previously reported cases is intervertebral foraminal extension, which is uncommon for a non-nerve sheath tumor.[14] [15] Therefore, schwannomas and capillary hemangiomas constitute the most frequent differential diagnosis. There are reports of spinal capillary hemangiomas in other locations, mainly the intradural and intramedullary spaces.[7] [8] [9]
The natural history of hemangiomas is poorly understood due to the scarcity of cases.[7] All four cases presented with progressive myelopathy and pain.[2] [4] Myelopathy is thought to be related to the direct compression of the spinal cord or vascular steal phenomena. The cases of epidural capillary hemangioma did not present any signs of hemorrhage.
In all cases, the lesion was located at the thoracic spine. Radiological features were identical in every case reported thus far. MRI findings include an isointense lesion in T1–weighted images, with high signal in T2 and significant enhancement after gadolinium injection. We observed low density rim in two cases.[2] [4] [5] Foraminal extension was radiologically appreciated in all cases, as well it was during surgical procedure. Such foraminal extension may be responsible for partial resection, even though no recurrence has been described thus far.[2] [4] [5]
Surgical resection should always be indicated, regardless of the clinical presentation, due to the risk of spinal cord compression.[5] [15] Laminectomy or laminotomy are the most used approaches. At surgery, the lesion presents as a reddish epidural mass with arterial feeders surrounding it. The surgeon must identify and divide the feeding vessels. It is important to carefully dissect the lesion itself circumferentially away from the dura and exercise judicious hemostasis. Total surgical resection is feasible, although intervertebral foraminal extension may preclude it.
Most epidural hemangiomas are cavernous, constituting an important histological differential diagnosis.[1] [3] [6] Cavernous hemangiomas are comprised of a large number of sinusoidal channels in collagenous tissue,[6] whereas the capillary hemangioma are composed of thin irregular capillary-sized vessels in a fibrotic stroma, determining a lobular architecture.[3] [14] Basal lamina is continuous and of low mitotic activity presenting no atypia. Capillary hemangiomas stain positively for CD 31 and CD 34;[1] [3] [6] [15] however, their reaction for S100 and epithelial membrane antigen is negative.[1]

Conclusion
Pure epidural capillary hemangiomas are extremely rare lesions that should be included in the differential diagnosis of spinal epidural lesions. They differ from more common lesions, mainly schwannomas, primarily due to their foraminal extension, which also may differentiate them from cavernous hemangiomas. Surgical excision is mandatory and intervertebral foraminal extension may preclude gross total resection.
