Parasitic Soft Tissue Infection Diagnosed by Point-of-Care Ultrasound.

People are now traveling more than ever to exotic destinations around the world. With this increased exposure to parasites and tropical disease, there is a greater likelihood of encountering exotic illnesses in the emergency department (ED). Point-of-care ultrasound (POCUS) has been used extensively to evaluate soft tissue infections and differentiate cellulitis from abscess. It is also commonly used to diagnose and localize foreign bodies in soft tissue. We present a case of parasite infestation diagnosed and localized by POCUS in the ED. Emergency physicians have become increasingly skilled at using POCUS for an expanding list of diagnoses. This unusual case of parasite localization and treatment highlights yet another use for POCUS in this age of travel to many tropical destinations. This article also reviews the lifecycle and preferred treatment of Dermatobia hominis, or human botfly infestation.
