Poco común pero significativo: un caso de hernia lumbar primaria tratada con reparación abierta con malla

We present a case of a male in his late 50s who reported a painless swelling in the left lumbar region, noticed 15 days earlier. Examination revealed a soft, reducible swelling. Contrast-enhanced CT identified a 2.8 × 2.8 cm defect in the inferior lumbar triangle containing omentum and large bowel. An open mesh repair was performed, confirming the diagnosis intraoperatively. The patient had an uneventful recovery. The patient was discharged on postoperative day 3 after drain removal, and was reviewed one week after discharge on an outpatient basis, where it was found to be healthy and sutures removed. The patient was followed up one and two months after discharge, and no recurrence was noted. This case highlights the diagnostic challenge of lumbar hernias due to their subtle presentation and rarity.
