MR imaging features of obturator internus bursa of the hip.

Hwang JY, Lee SW, Kim JO - Korean J Radiol (2008 Jul-Aug)

Bottom Line: The authors report two cases with distension of the obturator internus bursa identified on MR images, and describe the location and characteristic features of obturator internus bursitis; the "boomerang"-shaped fluid distension between the obturator internus tendon and the posterior grooved surface of the ischium.

ABSTRACT
The authors report two cases with distension of the obturator internus bursa identified on MR images, and describe the location and characteristic features of obturator internus bursitis; the "boomerang"-shaped fluid distension between the obturator internus tendon and the posterior grooved surface of the ischium.

28-year-old man with diffuse pelvic infection and reactive bursitis of obturator internus bursa.A. Transverse fat-suppressed Gd-enhanced T1-weighted MR image shows fluid collection with enhanced thin peripheral rim (arrows) between ischium (I) and obturator internus muscle and tendon (arrowheads). Inflammation was also noted in right inguinal area, lesser pelvis, and along sciatic nerve.B. Follow-up MR image 12 days later showing complete disappearance of fluid in obturator internus bursa and of soft tissue enhancement in right pelvic area.

Figure 2: 28-year-old man with diffuse pelvic infection and reactive bursitis of obturator internus bursa.A. Transverse fat-suppressed Gd-enhanced T1-weighted MR image shows fluid collection with enhanced thin peripheral rim (arrows) between ischium (I) and obturator internus muscle and tendon (arrowheads). Inflammation was also noted in right inguinal area, lesser pelvis, and along sciatic nerve.B. Follow-up MR image 12 days later showing complete disappearance of fluid in obturator internus bursa and of soft tissue enhancement in right pelvic area.

Mentions: A 28-year-old man presented with swelling and redness on the right inguinal and buttock area of two weeks duration. He also complained of intermittent fever and weakness in the right leg. Initial laboratory findings showed elevated ESR (66 mm/hr) and CRP (15.4 mg/dl) levels. MRI was performed to identify the infection focus and guide treatment planning, and showed a thin-walled fluid collection between the obturator internus tendon and the posterior surface of the ischium (Fig. 2A). The hip joint appeared normal. However, diffuse enhancement of soft tissue was noted in the right inguinal area, the lesser pelvis, and along the sciatic nerve. Diffuse pelvic infection with reactive bursitis of an obturator internus bursa was diagnosed based on clinical and MR imaging features. After eight days on antibiotics, his laboratory findings returned to the normal range, and follow-up MR 12 days later showed complete disappearance of the fluid pocket and of the soft tissue enhancement in the right pelvic area (Fig. 2B). He has since been asymptomatic.
