Abstract
The lumbar hernia is rare and may occur in the superior (Grynfeltt-Lesshft triangle) or inferior lumbar triangle (Petit triangle), two anatominal spaces of within the lumbar area. In this paper, a case of superior lumbar hernia was reported with some additional discussion on the related lierature.
The patient was a 72-year-old man complaining of a bulge in the left lumbar area. On examination, there was a 9×7×2 cm bulge beneath the 12th rib on the left side which became more prominent on coughing. Computed tomograph was useful in preoperative diagnosis of the lumber hernia showing a defect of parietal abdominal wall with herniating perirenal fat. In operative findings, a 4×3×3 cm mass of herniated fat and a 1.5 cm small hernial opening in the Grynfeltt triangle were identified. The herniated fat was excised and ligated. The defect of transversalis fascia was closed with interrupted suture, overlapping the adjacent fascial structure. The postoperative course was smooth and no recurrence have been observed.
In the Japanese literature, only 16 cases of lumbar hernia were seen and this case reported here would be the fifth case as the superior lumbar hernia.
