Recognition of internal larval motion on ultrasonography may help distinguish myiasis from abscess, foreign body or vascularized soft-tissue masses and guide definitive mechanical extraction.
PURPOSE: To describe dynamic ultrasonographic findings in travel-associated subcutaneous myiasis.
METHODS: A 54-year-old man with persistent nodular lesions after rural travel underwent gray-scale and color Doppler ultrasonography using a 13-MHz high-frequency linear transducer.
RESULTS: Imaging demonstrated an echogenic subcutaneous structure with posterior acoustic shadowing, surrounding hyperemia, and real-time rhythmic internal movement, supporting larval infestation.
CONCLUSION: Recognition of internal larval motion on ultrasonography may help distinguish myiasis from abscess, foreign body or vascularized soft-tissue masses and guide definitive mechanical extraction.
