The bursas are flattened sacs that act as a protective cushion, overlap between the bones and muscles (deep bags) or between bones and tendons / skin (superficial bags). These synovial sacs are filled with small amounts of liquid to facilitate movement during muscle contraction. The deep bags, such as subacromial and iliopsoas bag, are located in the band. The surface bags, such as the olecranon and prepatellar, are located in the subcutaneous tissue. Humans have about 160 bags. The bag of...

The protocol was approved by the hospital’s board and informed consent wasobtained by all patients. From June 2008 to September 2011 we evaluated 12 patients with iliopsoas bursitis diagnosed by MRI imaging performed before and two weeksafter treatment. The MR's sequences used were standardized:SE T2, T2 FAT SAT and T1 axial and GRE T2 coronal. All MRAs were performed by twoexperienced Consultant Musculoskeletal Radiologist. Theimages were interpreted by the sameRadiologists. In all cases the...

From the comparison of the MR imagingof bursal dimensionsby two different radiologists, respectively with 22 and 4 years of experience, in double-blind study, before and after treatment, we appreciated a complete resolution of bursal detention in 11 of 12 patients and a volumetricreduction of the 60% in 1 of 12 patients. The VAS scale underwent a reduction from a mean value of 7.6 pre-treatment to 1.3 post-treatment; pain did not change only in 1 of 12 patients.

Having regard to the clinical results strongly positive, the low cost and the rapidity of intervention we can say that the US-guided treatment by aspiration of the effusion and infiltration of corticosteroids in the bursa of iliopsoas is an optimal method for the treatment of this pathology.This research is an indication of the treatment and opens the way to further interventional - radiological's studies.
