Not One of the Usual Suspects: MRI Features of Insertional Lateral Cord Plantar Fasciopathy.

Objective: The purpose of this article is to report MRI findings of insertional lateral cord plantar fasciopathy and review the presenting symptoms of the condition and suspected diagnoses.

Conclusion: Lateral cord plantar fasciopathy presents with pain and swelling at the lateral midfoot, which are typically clinically suspected to be caused by fifth metatarsal (MT) base stress fracture of peroneal tendon abnormalities. The MRI findings are identical to those seen in association with the more commonly occurring central cord plantar fasciopathy, which has a calcaneal origin, but the findings affect the insertion of the lateral cord onto the plantar lateral base of the fifth MT.

Predictive MRI correlates of lesser metatarsophalangeal joint plantar plate tear.

Purpose: To identify correlated signs on non-enhanced MRI that might improve diagnostic detection of plantar plate (PP) tear.

Materials And Methods: We performed an IRB-approved, HIPAA-compliant retrospective analysis of 100 non-contrast MRI (50 PP tear, 50 controls). All were anonymized, randomized, and reviewed; 20 were duplicated to assess consistency.

MRI of lesser metatarsophalangeal joint plantar plate tears and associated adjacent interspace lesions.

Objective: To identify the variety of second and third intermetatarsal space (IS) lesions that may coexist with and without adjacent metatarsophalangeal joint (MTP) plantar plate (PP) tears.

Materials And Methods: One hundred forefoot MRIs in 96 patients with metatarsalgia obtained between 30 September 2011 and 21 July 2012 using 1.5- or 3-T MRI were retrospectively reviewed in consensus by two MSK radiologists and one podiatrist (DPM).

Synovial sarcoma of the foot.

We report the case of a 75-year-old male who underwent lung lobectomy for presumed lung cancer. Thereafter, he presented with a painful mass between the third and fourth metatarsal heads in the foot that was assumed to be Morton's neuroma. After extensive oncologic evaluation, the foot mass was diagnosed as a synovial sarcoma.
