60-year-old female, evaluate for Morton's neuroma. Please note evaluation for Morton's neuromas is limited given the lack of intravenous contrast administration. Some sequences are slightly limited by patient motion artifact.Left foot:There is a small 3 x 5 mm ovoid focus of low to intermediate signal intensity on non-fat-suppressed sequences and increased signal intensity on fat-suppressed sequences within the plantar fat beneath the interspace between the bases of the second and third proximal phalanges. While it is possible that this could represent a small Morton's neuroma, this is equivocal. No findings to suggest a Morton's neuroma within the interspace between the third and fourth rays or elsewhere.Mild osteoarthritis affects the first metatarsophalangeal joint with foci of metallic susceptibility artifact in the adjacent soft tissues suggesting prior surgery.The remainder of the forefoot appears normal.Right foot: There is an approximately 5 x 5 mm rounded focus of intermediate signal intensity on non-fat-suppressed sequences and slightly increased signal intensity on fat-suppressed sequences within the plantar fat beneath the interspace between the second and third metacarpal heads that could represent a small Morton's neuroma, slightly more prominent than that seen on the right.There is small amount of fluid in the intermetatarsal bursa between the third and fourth metacarpal heads, but no definite neuroma at this location. Mild osteoarthritis affects the first metatarsophalangeal joint with adjacent foci of signal voids suggesting metallic susceptibility artifact from prior surgery.The remainder of the forefoot appears normal.
1. Limited study due to lack of intravenous contrast administration showing a small nodular focus of signal abnormality within the plantar soft tissues beneath the interspace between the second and third metatarsal heads on the right that could represent a Morton's neuroma. A similar, but smaller finding is noted on the left.2. Osteoarthritis of the first metatarsophalangeal joint bilaterally with findings indicating prior surgery to this site.
