Objective

To investigate the MR imaging appearance of the trochanteric region in a group of patients referred for non-musculoskeletal conditions.

Materials and methods

Forty-five patients (n = 90 hips) referred for non-musculoskeletal conditions were imaged with a coronal T1 weighted fat saturated sequence after intravenous administration of contrast medium. Findings were interpreted by consensus of two experienced radiologists.

Results

In 54 of 90 hips (60 % ) no signal changes were seen at the level of the greater trochanter. A linear area of contrast enhancement with a craniocaudal dimension of less than 3 cm, and thickness less than 0.3 cm was seen in 32 of 90 hips (35.6 % ).

A fusiform area of contrast enhancement with a craniocaudal dimension of more than 3 cm, and thickness more than 0.3 cm was seen in 4 hips (4.4 % ).

Conclusion

An area of signal abnormality may be seen on contrast enhanced studies in asymptomatic persons, located in between the gluteus medius tendon and iliotibial band, and this should not be considered as a cause of pain in the trochanteric region.
