Patient
male, 64 year(s)
 
 
  • Figure 1
    Plain radiograph

    AP-view: a periosteal reaction with central lucency (arrow) is visible at the radial side of the diaphyse of the fourth metacarpal bone. No foreign body is visible.

     
     
     
  • Figure 2
    Plain radiograph

    lateral view: dorsal swelling (arrow)

     
     
     
  • Figure 3
    Axial view with ultrasound of the dorsal side of the right hand

    a large hypoechoic soft-tissue mass (arrows) superficially to the third (MC3) and fourth (MC4) metacarpals. The extensor tendons (stars) seem to be “pushed away” by the mass and are located at the periphery of the...

     
     
     
  • Figure 4
    Sagittal view with ultrasound of the dorsal side of the right hand

    linear hyperechoic structure (arrows) penetrating in a anteroposterior way between the fourth metacarpal (MC4) and the capitate bone (CAPITATUM)

     
     
     
  • Figure 5
    axial T1-weighted image

    subcutaneous, hypointense mass (star) located in the back of the hand and centered on the fourth metacarpal.

     
     
     
  • Figure 6
    axial T2-weighted image with fat suppression

    the dorsal mass (star) is heterogeneous and hyperintense. The dorsal extension (arrow) between the third and fourth metacarpal with a target appearance is well appreciated: central hypointense foreign body surrounded...

     
     
     
  • Figure 7
    axial T1-weighted images after injection of gadolinium and with fat suppression

    intense and diffuse enhancement of the dorsal subcutaneous soft-tissue mass (arrow). The route of the foreign body (dashed arrows) is very clear and the abutment of the foreign body on the bone explains the central...

the dorsal mass (star) is heterogeneous and hyperintense. The dorsal extension (arrow) between the third and fourth metacarpal with a target appearance is well appreciated: central hypointense foreign body surrounded by hyperintense inflammatory tissue.
 
intense and diffuse enhancement of the dorsal subcutaneous soft-tissue mass (arrow). The route of the foreign body (dashed arrows) is very clear and the abutment of the foreign body on the bone explains the central lucency of the periosteal reaction, visible on plain radiograph.
