Imagenological findings of external snapping hip syndrome. Case report

Introduction: External snapping hip syndrome is characterized by a painful sensation accom­panied by an audible snapping noise in the hip when moving. Even though orthopedists are widely aware of this condition, imaging findings still need to be recognized by all radiologists in order to provide more information that allows for the best multidisciplinary treatment. Z-plasty of the iliotibial band is the most used treatment with the best results. Case presentation: Female patient with bi­lateral external hip snapping syndrome on the right side, who was treated initially in a con­servative manner without adequate response; hence, she required surgical management with arthroscopy. All treatment options used for this patient were not successful, and symptoms recurred. Discussion: The diagnosis of snapping hip syndrome is mainly clinical. However, the con­tribution of diagnostic imaging is important to characterize the structures involved in this nosological process, in order to develop the therapeutic planning and do the follow-up. Conclusion: Knowledge on ultrasound and magnetic resonance findings related to this pathology allows radiologists to identify this syndrome and contribute to a timely treatment.
