Spinal epidural hematoma after a pathologic compression fracture: an unusual presentation of multiple myeloma.

BACKGROUND CONTEXT: Spinal epidural hematoma can result from traumatic and atraumatic etiologies. Atraumatic spinal epidural hematomas have been reported as an initial presentation of multiple myeloma. There are no other reports previously describing spinal epidural hematoma after a pathologic spinal fracture.

PURPOSE: To present the first reported case of a spinal epidural hematoma after a pathologic fracture and a very unusual initial presentation of multiple myeloma in a young patient.

STUDY DESIGN/

SETTING

Case report.

METHODS

A healthy asymptomatic 37-year-old male was struck in the head with a ball while playing soccer. Initial symptoms included severe back pain without neurologic symptoms. Complete motor paralysis developed over the next 24 hours in the lower extremities with a sensory level of T10. Magnetic resonance imaging evaluation of the spine revealed a T6 compression fracture with a dorsal T3 to T10 epidural hematoma. The patient underwent surgical T2 to T8 posterior spinal decompression with evacuation of the hematoma. Serum and urine electrophoresis and bone marrow biopsy were performed.

RESULTS

The results of the electrophoresis revealed an immunoglobulin A monoclonal spike. The bone marrow biopsy was positive for plasma cell myeloma. Recovery of some motor function was noted in both lower extremities postoperatively. The patient was subsequently started on steroids and chemotherapy for myeloma. The patient has also undergone bone marrow transplant, and his myeloma is currently in remission.

CONCLUSION

This is the first reported case of spinal epidural hematoma after a pathologic spinal fracture. Also, this case represents an unusual initial presentation of multiple myeloma in a young patient.
