Abstract：Objective: To study CT characteristics of giant lymph node hyperplasia and their pathologic basis. Methods: Seven cases of pathologically proved giant lymph node hyperplasia were examined by plain and enhanced CT scanning. Results: In 5 cases with localized type of giant lymph node hyperplasia, which belonged to hyaline vascular type pathologically, the lesion presented as a solitary round or oval, iso-density soft tissue mass with smooth border. After contrast administration, obvious homogeneous sustaining enhancement was observed. The 2 cases with disseminated type, belonged to plasma cell type pathologically, the lesion presented as many dissimilar size nodules, inhomogeneous density, indistinct border, the periphery fat plane was fuzzy, with mild moderate non-uniform enhancement, 1 case showed incomplete ring-like enhancement. Conclusion: CT findings of giant lymph node hyperplasia are closely associated with its pathology. For localized type(hyaline vascular type), it is possible to make a correct diagnosis preoperatively. For disseminated type(plasma cell type) carries no specific CT signs, its verification is mainly based on pathologic examination.
