Amputation of the right foot, swelling of the lower extremity There has been resection of the distal tibia and fibula at the level of the talocalcaneal articulation.There is cortical thinning and irregularity of the distal tibia and fibula. There is increased T2 signal within the marrow distally without definite corresponding low T1 signal. These findings are thought to reflect a combination of postsurgical change and reactive osteitis without definite osteomyelitis. The remaining marrow signal of the more proximal tibia and fibula is normal.There is diffuse soft tissue and muscular edema and inflammation of the lower leg. Following contrast administration, there is an irregular peripherally enhancing thick-walled fluid collection in the distalmost soft tissues overlying the amputation. Scattered areas of susceptibility artifact are noted relating to prior surgical intervention.
1. Surgical resection of the distal tibia and fibula with cortical thinning and irregularity of the remaining cortex. There is abnormal T2 signal without definite corresponding abnormal T1 signal in these findings are thought to represent a combination of postsurgical change and reactive osteitis without definite osteomyelitis.2. Irregular enhancing fluid collection within the distalmost soft tissues concerning for abscess.These findings were discussed with the ordering physician Dr. R. Krishnamoorthi at the time of interpretation.
