Abstract:
Objective To study the clinical features of hepatic pseudolymphoma.Methods A retrospective study was conducted on 19 patients with hepatic pseudolymphoma who were diagnosed and treated at Zhongshan Hospital in Shanghai from June 2013 to December 2017.Eighteen patients were females and one was a male.The mean age was (55±9) years,range 36 to 68 years.This study mainly analyzed the imaging features,treatment and postoperative results.Results All patients were diagnosed accidentally,and 78.9％ patients did not exhibit any evidence of hepatic B viral infection.A monofocal lesion was found in 14 patients and multifocal lesions in 5 patients.Surgical treatment was performed in all the patients.The lesion size was (1.1±0.4) cm (range 0.5～2.4 cm).Ultrasound revealed hypo-or slightly hypo-echogenicity.On MRI,diffusion weighted imaging showed slight hyperintensity or hyperintensity,all lesions manifested as homogeneous and slightly hyperintensity on T2WI and hypointensity on T1WI.Dynamic enhancement pattern,wash in and wash out,degressive and persistent enhancement were observed in 16(55.2％),12(41.4％),and 1 (3.4％) patients,respectively.More than 70％ of lesions were diagnosed as malignant tumors on preoperative imaging.During a follow-up of 6 ～ 44 months (median:19 months),no patient developed metastasis or recurrence.Conclusions Hepatic pseudolymphoma commonly occurred in women with a small sized lesion.Due to the lack of specific clinical manifestations and imaging findings,preoperative diagnosis was difficult.Surgical resection is still the most optimal treatment.The patients usually have favorable prognosis.
