Ankylosing Spondylitis Complicating with Spinal Epidural Hematoma: A Case Report

Abstract

Ankylosing spondylitis (AS) is an inflammatory disease that most commonly affects vertebral and pelvic joints. It is characterized by ossification of all spinal ligaments, articular joints, and intervertebral discs in association with osteoporosis of the vertebral bodies, thus, rendering the spine prone to trauma, which, even if minimal, may cause serious neurologic complications. Spinal epidural hematoma( SEH) is a rare clinical condition. Etiologically, it may be traumatic or nontraumatic. Spontaneous SEHs occur more frequently than traumatic SEHs. Although rare, posttraumatic SEH occurs frequently in patients with AS. We report the case of a 71-year-old male patient who suffered from AS for more than 20 years and experienced tetraplegia as a result of an accidental fall. Cervical and thoracic SEHs were diagnosed by magnetic resonance image. The neurologic recovery was successful after early decompression surgery and rehabilitation. The purpose of this case report is to remind clinicians that SEH, although rare, commonly occurs in patients with AS, and that early diagnosis and treatment can contribute to good functional recovery. of an accidental fall. Cervical and thoracic SEHs were
