Toe nodule Within the interspace between the first and second toes at the level of the first proximal phalanx is a lobulated soft tissue lesion measuring approximately 3 x 1.4 x 2.9 cm in the greatest AP, transverse, and craniocaudal dimensions. This lesion abuts the surface of the proximal phalanx however there are no discrete osseous changes. This does not appear to arise from the joint space although this is unclear. Following contrast administration, there is thin multilobulated peripheral enhancement without discrete solid focus. There is associated soft tissue edema and fluid surrounding the lesion within the interspace and along the dorsum of the head of the proximal phalanx. No additional lesions are identified. There is mild subcutaneous edema of the foot particularly dorsally along the heads of the proximal phalanges but also within the plantar soft tissues. The remaining bone marrow signal is normal. Osteoarthritis affects the first MTP joint. There is a mild amount of fluid signal surrounding the flexor hallucis longus tendon.
