(Patient #1): MRI lower extremity before and after liposuction showing axial and coronal T1 images. Axial and coronal T1 images of the upper right thigh before (A) and after (B) liposuction shows persistent or recurrence of asymmetric prominence of the superficial fatty tissues within the lateral right thigh (short arrows). Similar fatty infiltration of the gluteus maximus and medius muscle (short arrows).

This prompted an MRI of her lower extremities (Figure 1) which demonstrated an increase in subcutaneous fat that infiltrated the thigh musculature. A repeat MRI of the lower extremities revealed a recurrence of the lipomatosis (Figure 1).

(Patient #2): MRI lower extremity showing axial and coronal T1 images. Axial and coronal T1 images of the left upper thigh/buttock region demonstrates asymmetric prominence of the superficial fatty tissues with reticulation in the posteromedial left buttock region (long arrows). No well-defined mass or lipoma.

It showed a smooth marginated asymmetric ovoid prominence of the superficial fat, grossly measuring 7.2 x 3.1 cm, representing an asymmetric fatty tissue proliferation or lipomatous proliferation (Figure 2).

(Patient #3): MRI of the lumbar spine. Axial T1 and sagittal T1 images before liposuction shows large, partially encapsulated fatty soft tissue mass (arrows) with in the deep subcutaneous tissues along the posterior aspect of the lumbar spine and sacrum extending from Lower L2 to the S4 level.
