Figure 1
(A, B) Clinical photographs of the patient showing distended abdomen with prominent veins. (C, D, E) The contrast enhanced CT. (C) Axial section. (D) Coronal section. (E) Three-dimensional reconstruction with a sagittal view from the left side. Blue stars indicate the solid areas of the tumour (HU: 25–35). Red stars indicate the lipomatous portions (HU: −60 to −85). Yellow arrow in (D) shows the displaced bowel loops to the right. (F) Intraoperative photograph of the tumour after laparotomy.

Figure 2
Sections from CT showing involvement of the bilateral kidneys and the superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). (A) Axial section at the plane of origin of SMA. Yellow arrow shows the SMA going through the lipomatous mass to the gut in the right side. Pink arrow shows lipomatous mass around the region of right renal hilum. Yellow arrowhead shows the displaced left kidney in the tumour mass. (B) Coronal section showing origins of SMA through the tumour mass (yellow arrow). Yellow arrowhead shows the displaced left kidney in the tumour mass. (C) Axial section at the plane of origin of IMA. Green arrow shows the IMA going through the tumour mass. (D) Coronal section showing origins of IMA through the tumour mass (green arrow). Yellow arrowhead shows the displaced left kidney in the tumour mass.

(A–D) Histopathological slides. (A) Microscopy show lobules of varying sized adipocytes admixed with increased stromal cellularity (H&E ×100). (B) Focal areas show myxoid background admixed with chicken wire capillaries (H&E ×200). (C) Atypical stromal cells (yellow arrowhead) (H&E ×400). (D) Atypical stromal cells admixed with scattered lipoblasts which show scalloped nucleus (yellow arrow) (H&E ×200). (E) Gross specimens following resection—shows three lobulated masses (with both lipomatous and solid elements) of size: 28×22 × 14 cm, 22×17×15 cm, and 8×4.5 × 2 cm.
