Lumboiliac or lumbar hernia is a rare defect in the posterolateral abdominal wall that may be inadvertently misidentified and interfere with the implantable pulse generator (IPG) portion of spinal cord stimulator (SCS) implants. We report the case of a 54-year-old Caucasian man with an incidental finding of a lumboiliac hernia in the inferior lumbar triangle of Petit with placement of an IPG in a SCS implant. With the assistance of surgical colleagues, the correct diagnosis was made intraoperatively. We describe the operative repair of the lumboiliac hernia with a synthetic mesh. A new IPG pocket was created above the mesh prior to proceeding with IPG placement. No recurrence of the hernia defect was observed on 2-month follow-up. It is important that pain physicians and neurosurgeons who perform SCS implants are aware of lumboiliac hernias to avoid potential diagnostic or management errors. Lumboiliac hernias should be included on the differential diagnosis of lumbar or flank masses. Confirmation with imaging may be necessary and definitive surgical treatment should be pursued.
