  • Figure 1
    Lateral radiograph of the foot

    Plain radiograph of the foot demonstrates multiple osteolytic lesions in midfoot and hindfoot and soft tissue swelling in plantar and dorsal surfaces.

     
    Area of Interest: Bones; Extremities; Musculoskeletal bone; Imaging Technique: Conventional radiography; Procedure: Image compression; Special Focus: Infection;
     
     
  • Figure 2
    CT of the foot

    Axial CT with bone window (a) shows severe alteration of bone structure of the foot, multiple erosions and irregular periosteal reaction. Sagittal CT with soft tissue window (b) demonstrate diffuse inflammatory...

  • Figure 3
    MRI images

    Sagittal (a) and axial (b) T1WI fat-saturated+C images reveal diffuse marrow oedema involving bones of foot and multiple spherical hyperintense lesions surrounded by low-signal-intensity rims, creating the...

  • Figure 4
    Ultrasonography of the midfoot

    Ultrasonography reveal some hypoechoic thick-walled lesions containing small hyperecoic foci, forming the “dot-in-circle” sign (arrow). They are surrounded by soft tissue swelling.

Plain radiograph of the foot demonstrates multiple osteolytic lesions in midfoot and hindfoot and soft tissue swelling in plantar and dorsal surfaces.
 
Axial CT with bone window (a) shows severe alteration of bone structure of the foot, multiple erosions and irregular periosteal reaction. Sagittal CT with soft tissue window (b) demonstrate diffuse inflammatory changes in subcutaneous tissues.
 
Sagittal (a) and axial (b) T1WI fat-saturated+C images reveal diffuse marrow oedema involving bones of foot and multiple spherical hyperintense lesions surrounded by low-signal-intensity rims, creating the “dot-in-circle” sign (arrows).
