Background:
Spinal intradural extramedullary capillary hemangiomas are rare vascular lesions. Although total resection is the first treatment, the efficacy of adjuvant therapies, such as steroid or radiation therapy, has not been investigated.
Observations:
A 74-year-old man presented with progressive back pain, gait disturbance, and left chest pain. Spinal magnetic resonance imaging (MRI) revealed an intradural extramedullary lesion at the middle thoracic level. Preoperatively, systemic steroid administration improved his chest pain and reduced the tumor size. The authors performed tumor extirpation. Because the tumor strongly adhered to the pia matter, in short, the tumor accompanied with partial subpial growth, subtotal resection was performed, leaving a thin layer of the tumor. A pathological examination revealed capillary hemangioma. His gait disturbance showed rapid improvement. Stereotactic cyber knife treatment was performed for the residual tumor at 1 month after the operation. Serial MRI showed a gradual decrease in the tumor size and no recurrence at 2 years after the operation.
Lessons:
When a tumor adheres to the spinal cord or nerve root, immoderate total resection should not be performed to avoid exacerbating the clinical symptoms. Adjuvant therapies, such as a systemic steroid administration or radiation therapy, may provide satisfactory control of spinal capillary hemangiomas.
