A rare case of osteoporotic spine fracture associated with epidural lipomatosis causing paraplegia following long-term cortisone therapy.
Cushing's syndrome is frequently associated with osteoporosis. Therefore, the incidence of osteoporotic spine fractures is significant. They are a rare cause of paraplegic syndromes. Additionally, epidural lipomatosis may occur in those patients. The combination of both fracture and lipomatosis may cause neurological deficit. A case of a young patient suffering from drug-induced Cushing's syndrome is reported. She developed progressive paraplegia. Radiographs demonstrated kyphosis of the thoracic spine from T7 to T9 and pathologic fractures. Urgent operation was planned to stabilize and decompress the spinal cord in the area of the kyphosis. Fortunately, magnetic resonance imaging (MRI) was conducted first. It confirmed pathologic fractures of T7-9 but also showed massive epidural fat extending from the level of T1 to T9. As suspected, laminectomy alone in the area of the fracture proved to be insufficient, as shown by myelography during operation. For treatment of paraplegia in this case of symptomatic epidural lipomatosis, an expanded laminectomy was necessary to remove all the epidural fat. Having undergone this procedure, the patient is now recovering from paraplegia. Our experience suggests that care should be taken before operative treatment of patients with pathological fractures in combination with Cushing's syndrome. In addition to vertebral fractures, epidural lipomatosis has to be taken into consideration. Those patients with neurological deficits have to be treated by an extensive laminectomy.
