Xanthogranulomatous pyelonephritis (XP) is an uncommon, chronic, destructive, granulomatous disease of the renal parenchyma. The condition is generally associated with long-term urinary tract obstruction and infection, although the precise etiology of disease remains unknown. The condition often mimics neoplastic and inflammatory diseases, and XP associated with actinomycosis is extremely uncommon. A 60 year-old male was admitted complaining of abdominal pain and weight loss. His radiological findings were suggestive of metastatic kidney cancer, and we performed radical laparoscopic nephrectomy and mesenterectomy for diagnostic purposes. Pathologically, actinomycosis combined with XP was evident. We report here a rare case of XP associated with actinomycosis.

The clinical manifestations and classification of pulmonary embolism (PE) were described,and the causes and risk factors were analyzed for venous and pulmonary embolism.The significance and methods for early diagnosis of pulmonary embolism were discussed.Some techniques for diagnosing and treating PE were introduced.It's pointed out that PE diagnosis and treatment may be changed greatly with the involvement of multi-slice CT and MRI in elementary hospitals,being standardized imaging examination techniques as well as developing treatment measures.

Objective To study the efficacy of bronchoalveolar lavage(BAL)combined with prone positioning in children with Mycoplasma pneumoniae pneumonia(MPP)and atelectasis and its effect on pulmonary function.Methods A prospective study was conducted on 94 children with MPP and atelectasis who were hospitalized in Ordos Central Hospital of Inner Mongolia from November 2020 to May 2023.The children were randomly divided into a treatment group and a control group,with 47 children in each group.The children in the treatment group were given conventional treatment,BAL,and prone positioning,and those in the control group were given conventional treatment and BAL.The two groups were compared in terms of fever,pulmonary signs,length of hospital stay,lung recruitment,and improvement in pulmonary function.Results Compared with the control group,the treatment group had significantly shorter time to improvement in pulmonary signs and length of hospital stay and a significantly higher rate of lung recruitment on day 7 of hospitalization,on the day of discharge,and at 1 week after discharge(P<0.05).Compared with the control group,the treatment group had significantly higher levels of forced vital capacity(FVC)as a percentage of the predicted value,forced expiratory volume(FEV)in 1 second as a percentage of the predicted value,ratio of FEV in 1 second to FVC,forced expiratory flow at 50%of FVC as a percentage of the predicted value,forced expiratory flow at 75%of FVC as a percentage of the predicted value,and maximal mid-expiratory flow as a percentage of the predicted value on the day of discharge and at 1 week after discharge(P<0.05).There was no significant difference in the time for body temperature to return to normal between the two groups(P>0.05).Conclusions In the treatment of children with MPP and atelectasis,BAL combined with prone positioning can help to shorten the time to improvement in pulmonary signs and the length of hospital stay and promote lung recruitment and improvement in pulmonary function.

Positron emission tomography/computed tomography (PET/CT) is valuable for the diagnosis of malignancies. However, PET/CT is unable to discriminate exactly between inflammation and a neoplasm. We report a case of a 50-year-old man with pulmonary paragonimiasis that was suspicious for lung cancer, as detected by PET/CT. The use of PET/CT revealed multilobulated consolidation on the right lung and patchy consolidation on the left lung, with increased fluorodeoxyglucose (FDG) uptake. In addition, the left paraaortic lymph node (LN) and peripancreatic LN showed enlargement with increased FDG uptake. Lung cancer with multiple lymph node metastases was suspected from the increased standardized uptake values (SUV >4.5) determined by PET/CT. We performed wedge resection via video-assisted thoracic surgery (VATS) and found Paragonimus westermani eggs in the involved tissues.
