The pseudoneuroma sign is an indirect sign of plantar plate tears at the metatarsophalangeal joint (MTPJ) on MRI. This sign refers to pericapsular ill-defined and eccentric to the intermetatarsal space soft tissue thickening and is helpful for raising the accurate diagnosis of a plantar plate tear and associated pericapsular fibrosis 1-3.
