Ganglion Cyst of the Foot Causing Second and Third Metatarsal Stress Reactions and Fractures: A Case Report

Ganglion cysts arising from the plantar aspect are rare, and the most common location of the foot and ankle is the dorsal aspect of the foot. We present a case of a 49-year-old man with pain in the right foot. Plain radiographs showed thinning of the cortical bone in the right second and third metatarsals, and MRI showed cystic lesions between the second and third metatarsals, resulting in stress reactions and fractures. The fracture gradually remodeled and completely healed following resection of the ganglion cysts. If plain radiographs show atypical changes in the metatarsal bone morphology, a ganglion cyst, as in this case, should be suspected, and MRI should be considered.
