Lumbar hernias represent a rare entity among the abdominal wall defects. They are rare defects involving two weak areas of the postero-lateral abdominal wall: the superior lumbar triangle of Grynfeltt-Lesshaft, which is the most common site, and the inferior lumbar triangle of Petit. Antomically Grynfeltt’s triangle is bounded: above by the twelfth rib, medially by the sacrospinalis muscle, laterally by the posterior border of the internal oblique muscle. This rare hernia can be classified as congenital (approximately 20%), generally associated with other malformations, or acquired (around 80%), presenting in adults spontaneously or secondary to trauma or surgical incisions. The hernial sac content is generally characterized by retroperitoneal fat. We present a case of a 80 years old man who presented right lower back pain associated with a palpable mass for 5 years. The past medical history revealed a not well defined surgical procedure for a right renal trauma. The diagnosis of incisional lumbar hernia was made by physical examination (Figure 1). Radiological investigations such as abdominal ultrasonography and CT scan were performed in order to confirm the clinical suspicion. CT scan showed a herniated renal cyst of 9 cm diameter through right superior lumbar triangle (Figure 2). The patient underwent a small lumbotomy and a polypropylene mesh was placed.
