title: Embryonal rhabdomyosarcoma of foot with expansive growth between metatarsals.
abstract: The case of a 14-year-old girl with rhabdomyosarcoma of the right foot is reported. Plain radiography showed a large nonspecific soft tissue tumor between the metatarsals with bowing of the metatarsals away from the mass. MR imaging showed a large soft tissue mass involving the metatarsals. The findings were conflicting, because the tumor had an infiltrative soft tissue mass and bowing of the metatarsals more suggestive of slow expansive growth. Bowing of short tubular bones may be a process similar to cortical saucerization, which is typically seen in Ewing's sarcoma, and it can be one of the findings of high grade neoplasms, such as embryonal rhabdomyosarcoma.
