Answer: E

Explanation

Pelvic lipomatosis, which is a rare benign disease of unknown etiology, results in overgrowth of mature non-cancerous fat cells in the pelvis. It is most commonly seen in elderly, obese, black males with hypertension.1 Symptoms from pelvic lipomatosis are related to compression of the urinary, lower intestinal, and vascular system. Although there are no established treatment guidelines, interventions are aimed towards relief of obstruction. While most cases never progress towards symptom development, upper urinary tract surgery is occasionally required for cases of severe symptomatology or those with evidence of urinary tract obstruction with deterioration of kidney function.2
