From the case: Foreign body: forearm

Ultrasound

Longitudinal

There is a echogenic focus in subcutaneous fat abutting a non-thrombosed superficial vein.
It shows Doppler artifact.

Size - 1 mm.

There is no local collection / hypoechoic granulation around foreign body.

Case Discussion

Findings favour metal dense foreign body in forearm. Like a renal calculus, there is twinkle artifact by metal foreign body and that helps to localize it.
