Hernias of the inferior lumbar space: diagnosis with US.

Inferior lumbar triangle hernia as a rarely reported cause of low back pain: a report of 4 cases

“…One case report was found that supported the consideration of ultrasound in the diagnosis of lumbar hernias, due primarily to the portability of the modality, making it more accessible in some localities. 17 The ability to detect defects between muscular and fascial layers, visualize herniated viscera, and differentiate a hernia from renal and other soft-tissue tumors is one of the advantages described by several authors of CT over other imaging modalities. 11,15,16,[18][19][20] Aguirre et al 20 express, among other justifications, the multiplanar capabilities of multi-detector row CT as being particularly useful because of the exceptional anatomical depiction.…”

Grynfeltt-Lesshaft lumbar hernia: a rare cause of bowel obstruction misdiagnosed as a lipoma

“…Potentially, if this had been investigated further at that time, the correct diagnosis could have been made earlier, avoiding the emergency admission with bowel obstruction and allowing for elective repair with a less invasive approach. Furthermore, it illustrates that ultrasound, if interpreted by appropriate specialists, can be used in diagnosis of lumbar hernias, as demonstrated before [ 8 ]. This might be of importance in specific situations like pregnancy, young age or in resource deprived areas.…”

Meyers' Dynamic Radiology of the Abdomen

“…The floor of Petit's triangle is composed of the underlying internal oblique and transversus abdominis muscles. While these triangles have been recognized as anatomic areas of weakness that may lead to unusual lumbar hernias, [95][96][97] it is also apparent that these structural defects may predispose to the ready transmission of extravasated pancreatic enzymes or blood-stained fluid to the subcutaneous tissues of the flanks. Thus, fluid in the retrorenal plane that lies behind the perirenal fat often tracks along the lumbar triangle pathway through a cleft between the medial border of the posterior pararenal space and the lateral border of the quadratus lumborum fat pad lying just anterior to the quadratus lumborum muscle (Figs.…”
