INTRODUCTION: Spinal epidural lipomatosis (SEL) involves hypertrophy of fat tissue in the extradural space, often associated with long-term corticosteroid therapy. Sometimes it causes severe spinal cord compression and the patient gradually becomes symptomatic. However, sudden onset of neurological deterioration is extremely rare. CASE PRESENTATION: We herein present a case of sudden paraplegia in a patient with thoracic SEL at 2 months after thoracic vertebral fracture, whose symptoms were consistent with a lesion at the same level as the SEL. Computed tomography scan showed no remarkable change in the degree of vertebral fracture at the time of neurological deterioration. We performed immediate decompression surgery and found hemorrhage and granulation tissue at the level of the fracture and removed it with the epidural fat tissue. The hematoma and granulation tissue were thought to be the cause of the acute deterioration. The patient recovered gradually from the paraplegia. DISCUSSION: Sudden paraplegia with SEL at the time of vertebral fracture has previously been reported, but this is the first report of SEL with delayed onset of paraplegia after an initial diagnosis of coexisting vertebral fracture.
