Analysis of MRI Imaging Features of Fallopian Tubal and Peritoneal Tuberculosis
Objective To explore the MRI features of fallopian tube and peritoneal tuberculosis(TB).Methods Clinical data,MRI and PET/CT manifestations of 21 patients with fallopian tube and peritoneal tuberculosis confirmed by pathology and laboratory examination,and 27 patients of epithelial ovarian cancer(EOC)with peritoneal metastasis involving the fallopian tube were compared and analyzed.The morphology,T1WI,T2WI,and diffusion weighted imaging(DWI)signal characteristics,apparent diffusion coefficient(ADC)values,and enhancement features were analyzed and studied.Results Of 21 patients,16 were unilateral(9 on the left and 7 on the right),and 5 were bilateral.10 cases of fallopian tubes were rod-shaped,4 were mass-like,and 12 were sausage-shaped or L-shaped.The lesion showed slightly high signal on T1WI,moderate signal on T2WI,and high signal on DWI.The ADC value measurement range is 0.75-1.02 × 10-3mm2/s.Size of fallopian tube lesions range from 0.7 × 2.2cm to 1.5 × 4.5cm.The thickness of the peritoneum ranges from 1.6 to 3.2mm,presenting as smooth uniform thickening.Conclusion Non mass-like changes such as tubular or S/L shaped fallopian tubes,thin uniform thickening of the peritoneum,and slightly high signal on T1WI are characteristic manifestations of fallopian tube and peritoneal TB.
