A Morel-Lavallee lesion (MLL) is a posttraumatic soft-tissue injury characterized
by an accumulation of blood, lymph, and other physiologic breakdown products
between subcutaneous tissue and underlying fascia. It was first described as
occurring over the proximal lateral thigh, but it has since been documented at
various anatomic locations. Diagnosis is typically made by careful physical
examination and a radiographic analysis, most commonly with magnetic resonance
imaging (MRI). Recently, musculoskeletal ultrasound (US) has been recognized as a
useful adjunct to and potential replacement for MRI in the diagnosis and
monitoring of an MLL. We present a case report of a patient with an MLL of the
knee. We obtained magenetic resonance (MRI) and US images at the time of
diagnosis, and follow-up US images during convalescence. By doing so, we were
able to identify several key sonographic findings of an MLL at this location and
compare them with MRI. Although there have been several published reports to date
that describe the use of musculoskeletal US in the diagnosis of MLL, this is the
first of which we are aware that does so at the knee.
