A Rare Case of Herniated Renal Cyst Through Grynfeltt’s Triangle

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. Read more>>>>>>>
