30-year-old male with history of foreign body versus soft tissue calcification. MRI of the right foot was performed without contrast enhancement. A marker is placed along the plantar aspect of the fifth metatarsal head along the area of the patient's pain. In this region there is mild reticulation of the subcutaneous soft tissues consistent with edema. However, the small radiopaque foreign body seen on prior radiographs cannot be clearly visualized on MRI. There is no discrete fluid collection in this region. Marrow signal of the adjacent fifth metatarsal appears within normal limits. The remainder of the foot appears normal.
The small foreign body seen on prior radiographs cannot be clearly identified on MRI. There is mild subcutaneous edema surrounding the fifth metatarsal head along the area of the patient's pain, without discrete fluid collection or bone marrow signal abnormality. If further imaging evaluation is warranted, targeted ultrasound may be considered.
