dc.description.abstractBackground: Intersection syndrome describes a painful pathology occurring at the crossing of tendon sheaths, commonly noted in the forearm in the setting of overuse injury. Rarely, intersection syndrome may occur in other areas of similar musculotendinous intersections; one such location, the chiasma crurale, describes the intersection of the flexor digitorum longus tendon and the posterior tibialis tendon located on the posteromedial leg. Magnetic resonance imaging of the chiasma crurale in cadaveric legs has previously been observed; however, no clinical pathology has been reported on MRI. Case Information: A 64-year-old female (BMI: 44.3) with a past medical history of pes planus, bilateral knee replacement, and unspecified discectomy, complains of recurrent shooting pain in her left lower extremity that has been worsening for the past 3 weeks without improvement from an ambulatory boot. She is tender to palpation at the insertion of the PTT, sinus tarsi, and great toe. She was offered surgical and conservative options for treatment and opted for conservative treatment with an ambulatory boot. Conclusions: In this case report, we present a novel clinical finding discovered on ankle MRI, of intersection syndrome of the chiasma crurale.en_US
