Pseudocyst formation after abdominal liposuction—extravasations of Morel–Lavallée on MR images

A swelling of the abdominal wall in a 27-year-old woman after undergoing liposuction is described. Pseudocyst of Morel-Lavallée was located within the abdominal fascia and removed by surgery. MRI showed a non-homogenous mass with hyper intense fluid level and septations in T2-weighted images. We speculated that MRI can be used to guide the treatment (conservative or surgical). The literature concerning liposuction is reviewed.
