ABSTRACT

Objective 　To investigate methods for the diagnosis and treatment of primary angitis of central nervous system (PACNS). Methods　Radiological and clinical feature, operative resutls of 12 patients with mass lesion presentations of PACNS were analyzed retrospectively. Results　The lesions showed low density on CT and long T1 and long T2 signal on MRI. The ring-wall enhanced lesions on MRI were flowery in 7 patients. Gross total resection of the lesions were performed in 10 patients with excellent recovery postoperatively. Growth of lesions were observed in 2 patients who underwent subtotal resection. Conclusions　 Lesions of PACNS have special appearance on enhanced MRI. More patients with mass lesion presentations of PACNS could be diagnosed preoperatively according to radiological and clinical feature.For these patients, surgery is the optimal treatment at present.
