Intramedullary Spinal Capillary Hemangioma: Case Report
Arq. bras. neurocir; 36 (2), 2017
Publication year: 2017
Capillary hemangiomas involving the neuraxis are very uncommon. In the spinal cord,
they are located mainly intradural and extramedullary. To our knowledge, only four
cases in conus medullaris have been previously described. In our case, a 46-year-old man
was admitted with back pain, sphincter disturbances, as well as progressive weakness
and numbness on the lower extremities. Magnetic resonance imaging revealed an
undefined intramedullary lesion on the conus medullaris. The patient underwent
microsurgery, which achieved complete removal. Histopathological diagnosis was
compatible with capillary hemangioma. His postoperative course was uneventful and
all symptoms, including bladder dysfunction clearly regressed. The treatment of
intramedullary capillary hemangiomas is very critical in preventing unnecessary
morbidity, providing accurate information with respect to prognosis, and establishes
a regular outpatient follow-up. The natural history of this lesion involving the spinal cord
is not well described, although they are common elsewhere in the body.
Hemangiomas capilares que envolvem o neuroeixo são raros. Quando localizados na
coluna vertebral, geralmente são intradurais e extramedulares. Até a presente data
somente 4 casos de hemangiomas no cone medular foram descritos. O caso refere-se a
um homem de 46 anos com dor lombar, alterações esfincterianas, fraqueza e
parestesias em membros inferiores de evolução progressiva. Ressonância magnética
demonstrou lesão no cone medular de aspecto indefinido. Submetido a remoção
microcirúrgica completa. Histopatológico compatível com hemangioma capilar. O pósoperatório ocorreu sem intercorrências e houve recuperação dos déficits, inclusive da
disfunção esfincteriana. O tratamento dessa lesão não deve acrescentar morbidade. A
história natural dessa lesão na medula espinhal ainda não está definida, apesar de ser
uma lesão comum em outras partes do organismo.
