Abstract: | A 2‐year‐old girl presented with a 2‐month history of an erythematous, indurated plaque with well‐defined borders on the third toe of the right foot. Bedside high‐resolution ultrasonography demonstrated a thickened epidermis overlying a hyperechoic focus within the dermis. Her clinical and sonographic presentation was in keeping with a foreign body causing hair‐thread tourniquet syndrome. The foreign body was surgically extirpated without neurovascular sequelae. Ultrasonography expedited accurate diagnosis and is a promising adjunct to clinical evaluation for radiolucent foreign bodies. |
