Symptomatic Expansile Vertebral Hemangioma Causing Conus Medullaris Compression

Primary care physicians treating patients with low back pain should be aware of neurologic red flags requiring prompt attention. Magnetic resonance imaging is the imaging modality of choice when evaluating a neurologic abnormality presumably related to a space-occupying lesion. Although a disk herniation is the most common cause of these symptoms, clues in the history and examination must prompt physicians to expand their differential diagnosis to include a variety of other extradural masses (J Manipulative Physiol Ther 2005;28:000-000).
