Pelvic lipomatosis. Diagnostic role of ultrasonography and case report.

The authors report the ultrasonographic findings in a case of pelvic lipomatosis presenting with pathognomonic radiographic features. Ultrasound alone may exclude other lesions but cannot make a specific diagnosis because the sonographic appearance of fat is often conflicting. Ultrasonography should be of value as a follow-up examination in patients with definite risk of progressive ureteral obstruction.
