title: Intraosseous ganglion of the metatarsal bone.
abstract: We describe a rare case of intraosseous ganglion arising in the metatarsal bone. Radiographs revealed an osteolytic lesion with a fracture in the third metatarsal bone. A biopsied specimen exhibited hyaline fibrous tissue with marked myxoid change. Gadolinium-enhanced MRI, which revealed the network-like enhancement of the rim of the lesion and polycystic lesions adjacent to the joint, was helpful in making a diagnosis of intraosseous ganglion.
