Case Report on a Primary Grynfeltt Lumbar Hernia

A weakening in the postero-lateral abdominal wall can lead to the development of lumbar hernia. These defects are usually common in the Petit's inferior triangle or the Grynfeltt-Lesshaft superior triangle. As it is a rare entity, it is often missed in diagnosis , leading to a delay in management. We present a case of a 45 year-old male with no previous surgery who presented with a mass in the right lumbar region for last 1 year. The lump gradually increased in size and caused a vague dragging pain. On Computed tomography, the diagnosis of left Grynfeltt hernia was made. The patient underwent a laparoscopic mesh repair and had an uneventful postoperative hospital stay. Although it is a rare entity, there should be a high degree of suspicion of a lumbar hernia while evaluating a case of a lumbar mass. Early diagnosis by computed tomography and management with open or minimally invasive techniques can prevent future complications.
