1 From the Department of Radiology (M.E.H., B.R.H., E.M.R., D.D.) and Glickman Urological Institute (B.R.H., I.S.G.), the Cleveland Clinic Foundation, 9500 Euclid Ave, Desk Hb6, Cleveland, OH 44195. Received October 28, 2002; revision requested January 8, 2003; revision received January 21; accepted March 4. Address correspondence to B.R.H. (e-mail: hertsb@ccf.org).

Use of three-dimensional (3D) volume-rendered helical computed tomography (CT) in surgical planning before laparoscopic adrenalectomy was evaluated in a retrospective study. In 35 consecutive patients before laparoscopic adrenalectomy, 3D volume-rendered CT scans were created from helical CT scans. Videotapes that showed anterior, lateral, posterior, and posterocephalic approaches were assessed retrospectively. The relationship (not contacting, abutting, displacing, or invading) of adrenal masses to adjacent organs (diaphragm, liver, spleen, kidneys, stomach, pancreas, and vessels) was recorded and compared with findings in surgery reports. When such findings were available, they corresponded to those in the videotape. Three-dimensional volume-rendered CT successfully displayed the relationship of adrenal masses to adjacent anatomic structures and organs before laparoscopic adrenalectomy.
