BACKGROUND Inflammatory pseudotumor-like follicular dendritic cell(IPT-like FDC)tumors of the liver is an uncommon tumor with extremely low incidence.To date,the radiologic findings of this tumor in multiphase computed tomography(CT)and magnetic resonance imaging(MRI)imaging have not been described.CASE SUMMARY Patient 1 is a 31-year-old Chinese female,whose complaining incidentally coincided with the finding of multiple liver masses.In the local hospital,an abdominal enhanced CT found two hypo-dense solid lesions,with heterogeneous sustained hypoenhancement,in the upper segment of the liver’s right posterior lobe.In our hospital,enhanced magnetic resonance imaging(MRI)with hepatocyte-specific contrast agents showed a similar enhanced pattern of lesions with patchy hyperintensity in the hepatobiliary phase(HBP).The patient underwent surgery and recovered well.The final pathology confirmed an IPTlike FDC tumor.No recurrence was found on the regular re-examination.Patient 2 is a 48-year-old Chinese male admitted to our hospital for a huge unexpected hepatic lesion.A dynamic enhanced abdominal CT revealed a huge heterogeneous enhanced solid tumor in the right lobe of the liver with a size of 100 mm×80 mm,which showed a heterogeneous sustained hypoenhancement.In addition,enlarged lymph nodes were found in the hilum of the liver.This patient underwent a hepatic lobectomy and lymph node dissection.The final pathology confirmed an IPT-like FDC tumor.No recurrence was found upon regular re-examination.CONCLUSION When a hepatic tumor shows heterogeneous sustained hypoenhancement with a patchy enhancement during HBP,an IPT-like FDC tumor should be considered in the differential diagnosis. 展开更多

Objective:To develop nursing adverse events’reporting content of hospital.Methods:The study included two phases.The first phase was to develop the category and definition of nursing adverse events that need to be reported through an expert meeting.The second phase was to develop every nursing adverse event’s reporting content by using the Delphi method.In total,8 experts attended the meeting and 15 experts conducted two rounds of consultation letter.Results:Nursing adverse events that need to be reported of hospital include pressure sore,fall/falling from bed,unplanned extubation,medication error,and accident.Reporting content of these events in detail had also been obtained,which was helpful for cause analysis systematically.Conclusions:The reporting content of the nursing adverse event of hospital is established,and it is a basis for further study of the development of nursing adverse event reporting and feedback system. 展开更多
