Primary lumbar hernias are rarest form of hernias as compared to other ventral abdominal wall hernias. Only scattered reports of hernias of both superior and inferior lumbar triangles have appeared in both the English and foreign literature. There are only about 300 cases of primary lumbar hernia being reported. Being a rare entity, it had always posed diagnostic and treatment dilemma to the surgeons. The diagnosis requires imaging studies in such cases. Treatment of lumbar hernia is always surgical and requires prosthetic reinforcement for the best result. We are reporting here a case of primary lumbar hernia of the superior lumbar triangle with a successful repair with a sheet of polypropylene mesh. In our case, acquired primary lumbar hernia was emerging from superior lumbar triangle, associated with congenital right scoliosis, which is a rare occurrence.
