Management of Large Retroperitoneal Lipoma in a 12-Year-Old Patient

Retroperitoneal lipoma; a benign condition with frightening presentation

“…Fine needle and tru-cut biopsies were performed by many centers to confirm the diagnosis of the retroperitoneal lipoma before surgical intervention, while others do not recommend preoperative biopsy as the condition is recognizable by imaging, and, in addition to that, the result of the preoperative decision does not affect the type of the management offered to the patient. [1,2,[8], [9], [10]]. The CT scan of the current case was typical for the retroperitoneal lipoma.…”

“…Lipoma is a benign proliferation and collection of mature fat cells [1]. It is the most frequent soft tissue tumor in adults [2]. Currently, the exact underlying etiology is not well understood [1].…”

“…Currently, the exact underlying etiology is not well understood [1]. However, several theories have been proposed like glucose metabolism disturbance, hormone therapy and seeding after resection of a fibroid [2]. Lipomas are classified according to the morphologic characteristics into fibrolipoma, conventional lipoma, angiolipoma, myelolipoma, spindle cell lipoma, and myelolipoma [2].…”

Giant Adrenal Incidentaloma- Reporting a Rare Case

“…5 Rare sites of lipoma is in the retro peritoneum. 6,7 and adrenal gland. 8,9,4,10 The patient we are reporting had a large lipomatous tumour occupying almost entire left side of abdomen displacing entire pancreas and spleen anterosuperiorly and kidney posteroinferiorly but without causing any pressure effects except for vague back pain (?due to stretching of pancreas) which was encapsulated and dissectible from all the adjacent structures except for superior pole of kidney to which it was densely adherent and had to be separated by sharp dissection using electro cautery-which confirmed the pre-operative suspicion of this being a adrenal tumour (as reported on CT scan abdomen based on fat attenuation values and absence of identifiable left adrenal gland)…”
