There is medial ankle soft tissue edema centered on the posterior branch of the paired posterior tibial veins as it runs through the tarsal tunnel. There is a heterogenous high signal centrally within the lumen of the vein on PDFS sequences surrounded by a peripheral rim of low signal. The posterior tibial vein abuts the swollen posterior tibial nerve. The posterior tibial nerve is demonstrating internal high signal. On the coronal images, there is denervation edema signal seen in the quadratus plantae muscle (lateral plantar nerve innervation) and high signal in the inferior plantar nerve (Baxter's nerve).
