ABSTRACT
We report a non-obese patient suffering from spastic gait and right leg paresis caused by thoracic spinal cord compression secondary to spinal epidural lipomatosis. Although spinal epidural lipomatosis is most often associated with the administration of exogenous steroid or endogenous Cushing syndrome, obesity also has been reported as a possible cause. However, idiopathic(non-glucocorticoid induced) spinal epidural lipomatosis in non-obese healthy man is an extremely rare disease and dose not have any good explanation for the abnormal fat deposition in spinal epidural space. We recently experienced a patient with idiopathic thoracic epidural lipomatosis in whom MRI and histopathology established the specific diagnosis. With a case report, brief review of the disease including clinical feature, diagnostic procedure and therapeutic considerations is described.
