Foreign body granuloma

Foreign body granulomas represent a tissue granulomatous reaction to retained foreign bodies

Clinical presentation

Foreign body granulomas typically present as a tender mass.

Radiographic features

Lesion morphology can vary widely and depends on the material, size and location of the foreign body 1.


High frequency (>10 MHz) linear probe is useful 1:

  • foreign bodies typically appear echogenic with posterior acoustic shadowing
  • foreign body granuloma appears as a hypoechoic halo that can consist of hematoma, edema and/or granulation tissue

Practical points

  • foreign body granulomas have been misdiagnosed as soft tissue tumors when a foreign body is not seen or recognized 1
