Intermetatarsal Coalition: Case Report, Literature Review, and Imaging Findings of an Underrecognized and Underdiagnosed Cause of Foot Pain

<div>29-year-old female with dorsolateral foot pain. Ultrasound in axial view of the proximal metatarsals (a) shows abnormal bony overgrowth in the dorsal border of the third and fourth intermetatarsal space. This is associated with adventitial bursal formation, soft tissue oedema, and increased vascularity. AP (b) and oblique (c) radiographs show abnormal articulation at the base of the third and fourth metatarsals with sclerosis at the site of the approximation. Coronal PDFS (d) with nonosseous coalition at the third and fourth intermetatarsal spaces. Associated periostitis and intramedullary oedema signal. Axial PD (e) and PDFS (f). Marrow oedema signal. Osteitis and periostitis. Abnormal articulation at this level with surrounding bone spurring.</div>
