| Purpose: We reviewed the sonographic features of Morel-Lavalle′e lesions by correlating
the US image findings with a lesion’s age.
Materials and Methods: We obtained the sonography reports of 20 Morel-Lavalle′e
lesions of the hip and extremities from 18 patients with a history of trauma. The US
images were reviewed to characterize the echogenicity, shape, homogeneity, margins,
location and size of the lesions. The results were correlated with the age of the
lesions and the clinical histories.
Results: All the Morel-Lavalle′e lesions were hypoechoic or anechoic fluid collections
located between the subcutaneous fat and the underlying fascia. Regarding the
shape of the fluid collections, the lobular shaped lesions were all less than 21 days for
the lesion’s age, and the flat fluid collections were all greater than 1 month of age.
Regarding the homogeneity, the heterogeneous fluid collections were all less than 25
days of age, and the homogeneous fluid collections were all greater than 1 month of
age.
Conclusion: A Morel-Lavalle′e lesion is seen as a posttraumatic fluid collection in
the potential space between the subcutaneous fat and the underlying fascia on an
ultrasound examination. Acute Morel-Lavalle′e lesions tended to be heterogeneous
and lobular, and they became more homogeneous and flat in shape as the lesions
evolved. Awareness of these imaging findings will help us to properly diagnose Morel-
Lavalle′e lesions. |
