Right foot swelling There is diffuse subcutaneous edema of the foot particularly along the dorsal aspect of the metatarsals. Overlying the base of the third through fifth metatarsals is lobulated, ill-defined collection of fluid signal intensity. Further evaluation is somewhat limited given lack of intravenous contrast.There are erosions of the midfoot and tarsometatarsal articulation particularly involving the base of the first, third, and fourth metatarsals. Additionally, there is erosion of the head of the first metatarsal with a large associated soft tissue component. There are scattered areas of increased T2 marrow signal particularly in the bases of the metatarsals however there is no corresponding low signal on T1 to suggest osteomyelitis. There is no abnormal joint fluid within the foot.
1. Scattered erosions of the midfoot and metatarsals with a soft tissue component associated head of the first metatarsal. These findings are more suggestive of an inflammatory arthropathy such as gout. Correlation with radiographs recommended. There is no abnormal T1 signal to suggest osteomyelitis and there is no evidence of abnormal joint fluid to suggest septic arthritis.2. Diffuse subcutaneous edema foot with an ill-defined lobulated collection of fluid along the bases of the third through fifth metatarsals. Evaluation limited given lack of intravenous contrast however these findings may reflect phlegmonous change.
