Coccygeal fracture and Paget's disease presenting as acute cauda equina syndrome

Paget's disease of bone affects a significant percentage of adult and elderly patients. Although generally asymptomatic, the inflammatory changes and hypervascularity of the affected bone is prone to pathologic fracture and resultant hemorrhage. Epidural hematoma is well-described with vertebral fractures and can present as acute cauda equina syndrome. We describe a case in which an elderly female with Paget's disease sustained a minor coccygeal fracture and developed local hemorrhage and edema, which caused a sacral plexopathy that presented identical to acute cauda equina syndrome. A literature review will follow.
