Cervical intramedullary spinal cavernoma in setting of unresolved myelopathy: A case report

Background: Spinal cavernous malformations are rare, accounting for approximately 5–12% of all spinal cord vascular lesions. Fortunately, improvements in imaging technologies have made it easier to establish the diagnosis of intramedullary spinal cavernomas (ISCs). Case Description: Here, we report the case of a 63-year-old male with an >11-year history of left-sided radiculopathy, ataxia, and quadriparesis. Initially, radiographic findings were interpreted as consistent with spondylotic myelopathy with cord signal changes from the C3-C7 levels. The patient underwent a C3-C7 laminectomy/foraminotomy with instrumentation. It was only after several symptomatic recurrences and repeated magnetic resonance images (MRI) that the diagnosis of a ventrally-located intramedullary lesion, concerning for a cavernoma, at the level C6 was established. Conclusion: Early and repeated enhanced MR studies may be required to correctly establish the diagnosis and determine the optimal surgical management of ISCs.

Cervical Intramedullary Cavernoma in Children: Case report and literature review

Case presentation: A 10-year-old male patient was admitted due to posterior cervicalgia, vomiting and progressive generalized weakness. Physical examination showed difficulty in ambulation and tetraparesis. Magnetic resonance imaging (MRI) of the cervical medulla enhanced by the contrast agent, gadolinium, showed a poorly contrasted mass with a hemorrhagic center. We undertook a posterior cervicotomy (C1-C3). Post-operative evolution was satisfactory with complete regression of the deficits 90 days after surgery. Control MRI at intervals of 1 and 4 years confirmed absence of the tumor. Discussion: Cavernomas are vascular malformations, consisting of coarsely dilated vascular channels and coated by a single layer of endothelial cells, devoid of endothelium and myothelium. They represent only 5-12% of all vascular pathologies of the medulla, with only 10% affecting the pediatric population. There are only thirty cases of pediatric intramedullary spinal cavernomas in the literature, with predominance among males (2.1:1). Thoracic and cervical spinal cavernomas consist in 55% and 45% of the cases, respectively. In six cases (20%) cavernomatous lesions were associated with synchronic intracranial cavernoma. Among the reported cases, only one had poor evolution after surgery, whereas six patients persisted with prior symptoms. Conclusion: Spinal intramedullary cavernomas are rare entities, especially in the pediatric population, and are treated with surgery which improves prior neurologic deficits, besides preventing rebleeding

Physical examination showed difficulty in ambulation and tetraparesis. Gadolinium-loaded magnetic resonance imaging(MRI) of the cervical medulla, showed a poorly contrasted mass with a hemorrhagic center. We undertook a posterior cervicotomy(C1-C3). Post-operative evolution was satisfactory with complete regression of the deficits 90 days after the surgery. Control MRIat intervals of 1 and 4 years confirmed absence of the tumor. Discussion: Cavernomas are vascular malformations, consisting ofcoarsely dilated vascular channels and coated by a single layer of endothelial cells, devoid of endothelium and myothelium. Theyrepresent only 5-12% of all vascular pathologies of the medulla, with only 10% affecting the pediatric population.
