Sciatic Nerve Palsy due to a Superior Gluteal Artery Pseudoaneurysm PostBone Marrow Biopsy: A Case Report and Review of the Literature

J Orthop Case Rep. 2018 Jul-Aug;8(4):74-77. doi: 10.13107/jocr.2250-0685.1168.


Introduction: Sciatic nerve radiculopathy can present as a result of intraspinal or extraspinal causes. Intraspinal disorders can be disk hernia, spinal trauma, tumors, or infection, whereas extraspinal cause representsa disorder outside the lumbar spine. A gluteal artery (GA)false aneurysm can potentially compress the sciatic nerve and causes radiculopathy, with subsequent motor and sensory deficits. This condition can result mainly from trauma or infection, but it can also be iatrogenic.

Case report: We report a case of an 85-year-old male with a left sciatic nerve palsy as a result of a superior GA pseudoaneurysm post bone marrow biopsy (BMP). A short review of the literature regarding this topic is presented as well. Only a small number of similar cases are reported in the literature.

Conclusion: This case report emphasizes on the high suspicion index that the clinician should have managing a patient who suffers from sciatic nerve palsy with a history of a previous procedure around the pelvis' area, such as BMP.

Keywords: Pseudoaneurysm; bone marrow biopsy; sciatica.
