What are common differential diagnoses of plantar forefoot pain?
Metatarsal stress fracture, plantar plate tear, adventitial bursitis and Morton neuroma.
Where is the most frequent location for the condition?
Within the third webspace between the 3rd and 4th metatarsal heads as in this example.
Dumbbell/ovoid-shaped lesion (~ 12 x 5 x 15 mm) in the 3rd web space between the 3rd and 4th metatarsophalangeal joints. The lesion is isointense to muscle and hypointense to the surrounding adipose tissue in T1, T2, and PD images and slightly hyperintense compared to the surrounding fat in fat-saturated PD images. It displays strong enhancement after contrast administration.
