Nontraumatic spinal epidural hematoma (SEH) is a rare condition and the exact cause of the hemorrhage in SEH has never been established. However, there have been a few recent reports on some types of the epidural hematoma with a detectable origin of hemorrhage. We encountered a case of chronic SEH in a patient who had spondylolytic spondylolisthesis, which is also a rare condition to be associated with SEH. We report here on the radiologic findings of a case of chronic epidural hematoma in a patient who had spondylolytic spondylolisthesis at the L4-5 level, and we include a review of the related literatures.

Intraspinal synovial cysts are commonly found in the lumbar spine and occur less commonly in the cervical spine. Occurrence of a cyst in the thoracic spine causing myelopathy is extremely rare. We report here the radiological findings of a case of a thoracic intraspinal synovial cyst that caused myelopathy at the T2-3 level with an accompanying review of the clinical literature.
