Hemangioma of the Lumbar Spine Involving the Spinous Process: A Rare Case Report and Review of the Literature.

Hemangiomas of the spine are usually benign and asymptomatic. They can cause devastating complications such as pathological fractures of the spine and neurological disability. This report documents an atypical location of a hemangioma in a lumbar spinous process, in combination with a spondylolisthesis at the same level, which makes it even more uncommon. Surgery can be effective and safe and can significantly improve patient outcomes. Moreover, prior embolization can prevent acute hemorrhage in addition to providing careful diagnosis and evaluation.
