Image-guided Percutaneous Removal of an Intramuscular Sewing Needle Using Bone Marrow Biopsy Needle: A Case Report

A woman in her 40s was found to have a sewing needle within the right lumbar erector spinae muscle on imaging. The needle tip nearly reached the first lumbar vertebra and was close to the intervertebral foramen. An 8-gauge bone marrow biopsy needle was advanced under local anesthesia and biplane fluoroscopic guidance. The inner needle was withdrawn, while the outer needle was gently advanced to capture the proximal end of the sewing needle. The sewing needle was successfully grasped and removed using the endoscopic biopsy forceps. She was discharged without symptoms. Under biplane fluoroscopy guidance, percutaneous coaxial removal of the intramuscular sewing needle was successfully performed minimally invasively and at a low cost using an 8-gauge bone marrow biopsy needle and endoscopic forceps.
