Twinkle Artifact Observed During POCUS of a Human Myiasis Caused by the Dermatobia hominis Botfly

David Jerome; Matthew Stacey; Joseph Newbigging – An 81-year-old man presented to urgent care for assessment of an area of erythema and tenderness on his right thigh after recent travel to Belize. Point of care ultrasound (POCUS) revealed a hyperechoic structure with acoustic shadowing in the subcutaneous tissue. Colour Doppler assessment of the structure produced a twinkle artifact. The structure was removed and pathology identified the object as a Dermatobia hominis larva (human botfly).
