Presentation of lumbar intramedullary cavernous hemangioma by spindle-shaped hematoma sign on the spinal MRI: a case report.

Background: Cavernous hemangioma is a congenital insidious disease that can occur in any part of the central nervous system. In clinical practice, cavernous hemangioma is mostly found in the brain and rarely in the spinal cord. This study describes a case of a 34-year-old Chinese man of Han ethnicity with lumbar intramedullary cavernous hemangioma. On admission, lumbar intramedullary hemorrhage was observed in the patient, as well as a spindle-shaped hematoma sign was detected on the spinal magnetic resonance imaging. We suspected that the spinal hemorrhage could be associated with spinal cord cavernous hemangioma. The patient was started on dehydration and glucocorticoid therapy of mannitol on the day of admission and was diagnosed with cavernous hemangioma on the basis of his magnetic resonance imaging presentation and spinal cord histopathology results. However, there was no significant improvement in clinical manifestations following conservative treatment. It was exciting that the patient's condition improved after the surgical removal of hematomas.

Conclusion: Clinicians should consider lumbar intramedullary cavernous hemangioma in the differential diagnosis of early spinal cord hemorrhage with a spindle-shaped hematoma sign on the spinal magnetic resonance imaging.
