Bariatric barosensor: a new paired structure in the paravetebral region of the iliac crest

A new anatomical entity, which we have decided to name bariatric borosensor, is described. It represents a paired structure under the skin, supero-lateral to the posterior superior iliac spine, overlying the iliac crest at the level of the fourth lumbar vertebra. Each of the paired structure is about the size of an enlarged lymph node; 0.5–2.0 cm in the largest diameter, spherical or ovoid in shape and firm in consistency. They are easily palpated clinically and can be demonstrated objectively by ultrasound examination. A hypothesis is put forth, conjecturing that this new structure may have relevance to the problem of obesity in modern, civilised western societies.
