Abstract

Objective: To assess the imaging features of celiac ganglia on multi-detector row computed tomography (Mdct). Methods: We retrospectively reviewed 103 consecutive MDCT studies and recorded the frequency of visualization, location, morphologic feature, size, and enhancement pattern of the celiac ganglia. Results: The left celiac ganglion was visualized more often than the right ganglion (89% vs 67%, P < 0.0001). Both ganglia were identified at the level between the origins of celiac and superior mesenteric arteries and anterior to the diaphragmatic crura. The ganglia were either multilobulated or discoid in shape. The mean long- and short-axis dimensions of the ganglia were larger on the left than right (left: 2.2 [0.4] and 0.4 [0.1] cm; right: 2.0 [0.4] and 0.3 [0.1] cm, respectively, P < 0.005). The ganglia had the same CT attenuation as the adjacent adrenal glands on nonenhanced and portal venous-phase images in almost all cases and demonstrated higher attenuation than the adrenal glands in approximately two thirds of the cases on delayed scans. Conclusions: Celiac ganglia can be identified based on their characteristic locations and morphologic features on MDCT.
