Sažetak
Aims: The aim of the study was to evaluate accuracy of magnetic resonance imaging in diagnosis of piriformis muscle syndrome. Magnetic resonance imaging (MRI) can show anatomo-topographical relationship between piriformis muscle and sciatic nerve, detect changes in signal intensity and appearance of nerve, their surrounding, place and cause of nerve compression. Material and Methods: In ten elderly patients, 7 female and 3 males with long history of clinical symptoms of the piriformis muscle syndrome MRI was performed as last preoperative diagnostic tool. All patients were imaged using 2T MR system. Axial and coronal SE, FSE and fat suppressed FSE weighted images were made through pelvic region to show the whole piriformis muscle and course of sciatic nerve on its way out of pelvis through foramen infrapiriforme. Results: In five cases we found pathological substrate for piriformis muscle syndrome. In two women MRI demonstrated bigastric appearance of piriformis muscle with tendinous portion between the muscle heads and course of the common peroneal nerve through the muscle between the tendinous portions of the muscle. In two males and one female patients MRI showed a hypertrophic aspect of piriformis muscle and sciatic nerve has been anteriorly displaced. All MRI findings were confirmed surgically. In five patients it was not possible to see for certain any anatomo-topographical abnormality, but after surgical treatment, i.e. tenotomy of the piriformis muscle and neurolysis of sciatic nerve, all symptoms disappeared. Conclusion: MRI helps understanding complex anatomic relationship and makes nerve visible. Method is reliable for detecting cause of the nerve compression in piriformis muscle syndrome as well as in other tunnel syndromes.
