Contrast-enhanced abdominal CT in the axial (a) and coronal (b) plane demonstrates a well-demarcated tumor in the left hemiabdomen with a large fat component and areas of soft tissue attenuation (thin arrows) and displacement of jejunal loops (thick arrow).

The tumor was encapsulated in dense fibrosis and displaced surrounding jejunal loops to the midline (fig. 1).
Histopathological examination showed a well-defined fibrotic pseudocapsule encircling a pseudotumorous lesion (a), and variable proportions of steatonecrosis, numerous lytic microcysts and irregular surrounding fibroinflammatory reactions with abundant pools of foamy histiocytes (b).

The paraffin sections showed extensive fat necrosis, and variably expressed fibroinflammatory reactions with clusters of mononuclear inflammatory cells and lipid-laden macrophages suggestive of mesenteric lipodystrophy (fig. 2).
