Non-infectious ischiogluteal bursitis: MRI findings.

Cho KH, Lee SM, Lee YH, Suh KJ, Kim SM, Shin MJ, Jang HW - Korean J Radiol (2004 Oct-Dec)

Bottom Line: The superior ends of the bursal sacs abutted to the infero-medial aspect of the ischial tuberosity.On T2-WI, the bursa was hyper-intense in all cases (17/17, 100%); it was heterogeneous in 10 cases and homogeneous in seven cases.With contrast enhancement, the inner wall of the bursae was smooth (5/17 cases), and irregular (12/17 cases) because of the synovial proliferation and septation.

ABSTRACT

Objective: We wished to report on the MRI findings of non-infectious ischiogluteal bursitis.

Materials and methods: The MRI findings of 17 confirmed cases of non-infectious ischiogluteal bursitis were analyzed: four out of the 17 cases were confirmed with surgery, and the remaining 13 cases were confirmed with MRI plus the clinical data.

Results: The enlarged bursae were located deep to the gluteus muscles and postero-inferior to the ischial tuberosity. The superior ends of the bursal sacs abutted to the infero-medial aspect of the ischial tuberosity. The signal intensity within the enlarged bursa on T1-weighted image (WI) was hypo-intense in three cases (3/17, 17.6%), iso-intense in 10 cases (10/17, 58.9%), and hyper-intense in four cases (4/17, 23.5%) in comparison to that of surrounding muscles. The bursal sac appeared homogeneous in 13 patients (13/17, 76.5%) and heterogeneous in the remaining four patients (4/17, 23.5%) on T1-WI. On T2-WI, the bursa was hyper-intense in all cases (17/17, 100%); it was heterogeneous in 10 cases and homogeneous in seven cases. The heterogeneity was variable depending on the degree of the blood-fluid levels and the septae within the bursae. With contrast enhancement, the inner wall of the bursae was smooth (5/17 cases), and irregular (12/17 cases) because of the synovial proliferation and septation.

Conclusion: Ischiogluteal bursitis can be diagnosed with MRI by its characteristic location and cystic appearance.

Mentions: On the T2-weighted images, the bursa was hyper-intense in all patients (17/17, 100%; heterogeneously hyper-intense in 10 cases and homogenously hyper-intense in 7 cases). This heterogeneity was variable depending on the degree of the blood-fluid levels and septations within the bursae (Fig. 2).
