To evaluate magnetic resonance imaging (MRI) features of ruptured spinal dermoid tumors with spread of lipid droplets in the central spinal canal and/or spinal subarachnoid space and to understand the underlying mechanism. ⋯ Spinal dermoid tumors ruptured into central spinal canal and/or spinal subarachnoid space have unique MRI features. The absorption of lipid droplets within central spinal canal is rather difficult, and their movement is extremely slow. We propose that fatty components within the central canal of spinal cord may be partially associated with spinal dermoid tumors developmentally.

Review Case Reports
Ectopic pituitary adenoma associated with an empty sella: a case report and review of the literature.
A case of ectopic pituitary adenoma in the sphenoid sinus associated with an empty sella is reported. The coexistence of an ectopic pituitary adenoma and an empty sella is quite rare. ⋯ In the present case, the hypointense line that coated the pituitary gland was clearly demonstrated on 3-tesla T2-weighted magnetic resonance imaging. The hypointense line is considered to be the pituitary capsule and was critical in diagnosing this rare entity.

Review Case Reports
Stroke following epidural injections--case report and review of literature.
To describe a growing number of cases associated with spinal cord and posterior circulation ischemia as a complication of cervical epidural steroid injection (CESI). ⋯ Infarction is a rare but potentially devastating complication of CESI. It may occur despite the use of fluoroscopic guidance.
