Sinus Tarsi Syndrome : MRI
- Sinus Tarsi Syndrome usually presents with lateral foot pain and tenderness.
- Pathologically there is scarring and degenerative changes of soft-tissue structures in the sinus tarsi.
- Patients may have history of inversion injury with lateral ligament complex tears, and it is frequently associated with posterior tibial tendon injury.
- On MRI, in the acute setting there is increased signal in fat on T2 weighted images due to edema. The T1-hyperintense fat in the sinus tarsi space is replaced by either fluid or scar tissue, and the ligaments may be disrupted.
- Treatment is usually conservative
