Abstract: Objective To describe the CT features of giant lymph node hyperplasia in abdomen.Methods A retrospective study of CT features of giant lymph node hyperplasia in abdomen confirmed by surgery or biopsy pathology was performed.CT findings of all lesions were assessed by two radiologists including size,location,pattern of enhancement and density characteristics.Results 1 2 patients with giant lymph node hyperplasia in abdomen were confirmed including 7 women and 5 men with age range from 11 to 75 years (median age 3 9 years).All patients underwent pre-and post-contrast enhanced CT.CT showed a single mass in 9 patients lo-cated at retroperitoneum in 5,porta hepatic in 2,and mesentery in 2.Multiple masses were located at chest,abdomen and neck in 3.The lesions ranged in size from 1.2 to 11.9 cm in maximum diameter with an average size of 3.7cm.CT showed all lesions with well-defined margin and regular shape.The lesions less than 5 cm in diameter usually showed homogeneous enhancement,and how-ever those more than 5 cm showed heterogeneous enhancement.The calcification was seen in two patients.Conclusion CT features of giant lymph node hyperplasia in abdomen are characteristic.
