Methods The CT findings of 17 cases of patients with retroperitoneal paraganglioma, which were confirmed by pathological, were analyzed retrospectively. The plain and enhanced CT images and coronal reconstruction images features were analyzed in FUJI FILM workstations. The measureent was made including the form, size and image density of the lesions. Results 17 patients all made three periods of enhanced scan and coronary reconstruction. All lesions showed a kind of circular or irregular shape, the uniform or non-uniform density performance. Some lesions showed a sign of lobulation and calcification. All cases are in obviously enhanced, the maximum enhancement phase is at portal phase. 5 cases showed small vessels in arterial phase.
