Background
Deep gluteal síndrome is an underdiagnosis entity characterized by pain and dysesthesias in the buttock área,
hip or posterior thigh and/or radicular pain,
secondary to a nondiscogenic sciatic nerve entrapment in the subgluteal space.
It is known that extrasespinal sacral plexus and sciatic nerve entrapments may be result from a high espectrum of extrapelvic (within the subgluteal space) or intrapelvic pathology.
Due to the variation of anatomical entrapment,
the term “deep gluteal syndrome” may be a more accurate description of this nondiscogenic sciatica.
The etiologies may be grouped into traumatic,
inflammatory,
infectous,
vascular,
tumorous,
iatrogenic,
intrapelvic pathology,
primary (anatomical variants) and secondary muscle-tendinous entrapments (pirimorfis syndrome,
external rotators muscles entrapments,
gluteal pathology,
hamstring syndrome,
ischiofemoral impingement),
fibrous bands and others disorders
Because of the ever-increasing use of advanced MRI techniques and good to excellent outcomes of the new endoscopic treatment in sciatic nerve entrapments radiologists must be aware the anatomy and pathologic conditions of the subgluteal space.
