Best Practice Case Studies-Case 121 Asset 1 Morel-Lavallee Lesion

Video Transcription

Video Summary

This ultrasound consult explains how to identify a Morel-Lavallée lesion, a traumatic degloving injury between the superficial and deep fascia. Using a linear transducer, the examiner looks for a hypoechoic fluid collection with internal septations, compressibility, no Doppler flow, and sometimes fat globules. The talk also compares it with seroma, fat necrosis, and malignancy, noting that vascularity raises concern. Ultrasound is useful for layer assessment and speed, while MRI may better define large lesions and deeper associated injuries.
