CT manifestation of schistosoma haematobium cystitis

Objective To analyze CT manifestation of Schistosoma haematobium cystitis.Methods Retrospective analysis 32 patients,who were tested for Schistosoma haematobium cystitis using the urine filtration method.CT scan was performed for each patient with contrast enhancement.Results The vast majority of urinary tract schistomiasis lesions were in the urinary bladder.Calcification of the bladder wall was observed in all patients and mild enhancement in non calcified zone was found after intravenous contrast.Except for 5 patients of bladder cancer,the rest were no abnormality in size of bladder when bladder was filling or emptying.Ureteral wall annular calcification could also be identified in 25 patients.Twenty two patients were companied with ureteric hydronephrosis.Seminal vesicle calcification was seen in 4 patients among 11 male patients,while both uterine and ovarian in female and prostate in men had non calcification.Serious illness can be combined with bladder cancer.In 5 patients of patients with bladder cancer,bladder showed irregular soft tissue mass which was enhanced moderately after post-contrast scan,with vesical calcification in mass medially.Conclusion Bladder calcification is the most prominent CT feature of Schistosoma haematobium cystitis,which is useful in diagnosis the disease.
