Hematosalpinx in a 35-year-old woman with endometriosis. (a) Axial and (b) sagittal T2-weighted images show a tortuous, tubular structure with internal fluid-fluid level (white arrows) in the left adnexa. There are incomplete effaced mucosal and submucosal plicae along the tubal wall. (c) Axial and (d) sagittal fat-suppressed T1-weighted images show a distended fallopian tube with high signal intensity content (white arrows), a finding consistent with hematosalpinx. Note an endometriosic cyst in the omolateral ovary (arrowhead). (e) Axial DW image (b = 800 s/mm2) and (f) corresponding ADC map show that the lesion’s content demonstrates restricted diffusion with high signal intensity (white arrow) on DWI image and low signal intensity (white arrow) on ADC map
