There is tendinosis of the posterior tibialis tendon as it rounds the tip of the medial malleolus with mild tendon thickening. There is possible partial surface tearing of the anterior aspect of the tendon immediately distal to the tip of the medial malleolus (axial inversion recovery image #16) which is a possible hypertrophic tear less than 50% in cross sectional diameter. The study has been performed with the foot in neutral position. Confirmation of this possible partial tendon tear would require additional imaging with the foot in a plantar flexed position with transaxial images of the posterior tibialis tendon as it rounds the tip of the medial malleolus oriented perpendicular to the course of the posterior tibialis tendon.
