Spinal epidural lipomatosis-MRI
Spinal epidural lipomatosis is a disorder characterized by an abnormal accumulation of unencapsulated adipose tissue in the extradural space of the spinal canal. The distal lumbar spine and the mid and distal thoracic spine are the most commonly involved sites, with rare involvement of the cervical spine. Most cases have been attributed to long standing exogenous steroid administration. This is a 18 year old girl on treatment for neurocysticercosis on long term steroids presented with back ache. The dural sac will often have a characteristic geometric “Y-shaped,” polygonal spiculated or stellar deformation resulting from the presence of the meningovertebral ligaments.
