Imaging Considerations in Differentiating Plantar Plate Pathology and Webspace Neuroma.

Myriad pathologies affect the lesser toes. In this article, the focus is on the challenging radiological differential diagnosis of plantar plate (PP) degeneration and tear versus webspace neuroma. It is now understood that PP tear and even degeneration without tear is most accompanied by reactive pericapsular soft tissue thickening (pseudoneuroma), which contributes to neuritic symptoms that are often indistinguishable from webspace neuroma.

Postoperative MRI of the Ankle and Foot.

Many surgical procedures and operations are used to treat ankle and foot disorders. Radiography is the first-line imaging for postoperative surveillance and evaluation of pain and dysfunction. Computed tomography scans and MR imaging are used for further evaluation.

Metatarsalgia.

Although causes of metatarsalgia are multifactorial, in practice these most commonly include osseous stress reaction or fracture (including subchondral injury) and interdigital neuroma or plantar plate tear with adjacent pseudoneuroma. The various roles of radiography, ultrasonography, and MR imaging are discussed, and relevant technical issues and imaging findings are reviewed in order to facilitate accurate diagnosis and guide proper treatment of metatarsalgia.

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.
