Unusual cause of paraparesis in a patient with Cushing's syndrome.

Paraparesis is a rare manifestation in patients with Cushing's syndrome and the causes include vertebral compression fracture, hypokalaemia, spinal epidural lipomatosis, paraneoplastic syndrome and metastasis to the vertebrae and spinal cord. We report an unusual cause of paraparesis due to radiation-induced myelomalacia in a patient with adrenocortical carcinoma-associated Cushing's syndrome, who are predisposed to radiation-induced injury.
