54 year old male. Left great toe with erythema around the nail bed. History of diabetes. Evaluate for osteo/abscess. A superficial small ulcer at the medial aspect of the left great toe without associated abscess or evidence for osteomyelitis. There is a confluent fluid signal intensity collection at the dorsum of the foot that measures 8 mm in thickness and spans from the base of the toes into at least the midfoot, to the most proximal margin of this study. While this may simply represent confluent edema, infection cannot be excluded, though there are no specific features such as pathologic rim enhancement to suggest abscess formation. Diffuse atrophy of the plantar musculature of the foot.
1. Superficial small ulcer at the medial aspect of the great toe without evidence of osteomyelitis.2. Confluent fluid signal intensity collection at the dorsum of the foot, which may simply represent confluent edema although superimposed infection is not excluded. No specific features of this collection to indicate mature abscess formation.
