CT findings and diagnostic value of adrenal ganglioneuroma（five cases report and literature review）

Abstract:

Objective：To analyze the characteristics of CT findings of adrenal ganglioneuroma and to improve its diagnostic accuracy. Methods：CT findings and surgical pathological results of 5 patients with confirmed adrenal ganglioneuroma were retrospectively re－viewed and compared. Results：All 5 cases appeared as solitary lesion and all tumors were well defined，having embedded growth along the adjacent organs and blood vessels. Among the 5 cases，3 cases in the shape of water droplet located between diaphragmatic feet and inferior vena cava and 2 cases in the shape of leaflet located behind spleen vein. Plain scanning showed that 5 tumors，whose CT values were 24-35 HU，were uniformly low density and punctate calcification was observed inside 1 tumor. Enhanced scanning showed unobvious enhancement in the 5 cases during arterial phase and slight delayed enhancement in 3 cases during nephrographic phase，including 1 case with linear moderate delayed enhancement and 2 cases with unobvious enhancement. Conclusions：CT findings of adrenal ganglioneuroma have distinctive characteristics，which is helpful to diagnosis and differential diagnosis before operation.
