What are the CT and MRI features of pelvic lipomatosis?
Increased homogeneous nonencapsulated perivesical and perirectal pelvic visceral fat is seen, which surrounds the pelvic organs symmetrically. Superior displacement, a pear shape, or an inverted teardrop shape of the bladder, superior displacement of the prostate gland, and smooth narrowing of the rectosigmoid colon are also characteristically seen. Unilateral or bilateral hydroureteronephrosis may also occur
