PELVIC lipomatosis is a term used by Fogg and Smyth<sup>1</sup>in 1968 to describe the "overgrowth of normal fatty tissue, limited to the perirectal and perivesical spaces in the pelvis." This entity initially was reported by Engles in the five cases with radiolucent changes surrounding the pelvic viscera.<sup>2</sup>Since that time, approximately 60 cases have been reported. Its clinical and roentgenographic findings are well established, as are the major complications of infection and urinary tract obstruction. The association of pelvic lipomatosis and inferior vena caval obstruction has been made by Schechter in a single case report.<sup>3</sup>Further review of the literature yielded the report of congenital venous anomalies associated with pelvic lipomatosis.<sup>4</sup>To our knowledge, ours is the second report of pelvic lipomatosis as a primary disease entity with a resultant vena caval obstruction. <h3>Report of a Case</h3> A previously healthy 30-year-old man was admitted to The
