Fig. 3. Computed tomographic scans show (A ) the needle tip (arrow) cephalad to the celiac artery and (B ) the preaortic unilateral contrast spread cephalad and (C ) caudad to the celiac artery. The left side of the celiac area (quadrant 2 and 4 of fig. 1) is compressed–infiltrated by a tumor mass (asterisk). This pattern is consistent with two quadrants with contrast (quadrants 1 and 3 of fig. 1).
