“…The normal fallopian tubes are rarely seen on MRI unless surrounded by fluid as occurs in ascites. 7 When dilated, the fallopian tube appears as a fluid-filled tubular structure arising in the region of the uterine cornua and occupying the adnexa. The presence of multiple interdigitating folds of incompletely effaced mucosal and submucosal plicae have been described as a characteristic feature of a dilated fallopian tube.…”

Ectopic pregnancy is defined as implantation and subsequent development of an embryo outside the uterine lining. It has wide range of presentation from acute hemoperitoneum to chronic ectopic pregnancy. This is an unusual case of chronic ectopic pregnancy with large hematosalpinx without classical symptoms. A 22-year-old South Indian woman reported to the outpatient clinic with irregular spotting for a duration of 2 months which was not associated with pain. There was no preceding amenorrhea and previous menstrual cycles were regular. Clinically, the patient was hemodynamically stable but severely anemic. The abdomen was soft on palpation, cervical movements were not tender, and human chorionic gonadotropin was absent in the urine. Ultrasound revealed a complex adnexal mass. Magnetic resonance imaging (MRI) revealed a large hematosalpinx. Laparoscopic left salpingectomy was conducted and histopathology confirmed ectopic pregnancy. Ectopic pregnancy presents diagnostic dilemmas in the absence of classical symptoms. MRI and laparoscopy are important tools in such a diagnostic dilemma.

“…Nondilated fallopian tubes are not usually seen on MR images unless they are outlined by pelvic fluid [ 38 ]. In the presence of peritoneal fluid or contrast material, the fallopian tubes appear as paired, thin, serpentine juxtauterine structures extending either anteriorly or posteriorly into the cul-de-sac [ 39 ].…”

“…MR imaging features of an ectopic tubal pregnancy include [ 7 , 38 ] (Fig. 14 ): hematosalpinx (intermediate signal intensity on T1-weighted images and low signal intensity on T2-weighted images, due to the presence of deoxyhaemoglobin (an acute phase hematoma) [ 83 ]; enhancement of the dilated tube wall (from increased vascularity following implantation) [ 83 ]; presence of a gestational sac (it is seen as a cystic structure surrounded by a thick wall that has intermediate intensity on both T1-weighted with fat suppression and T2-weighted images, and that enhances after administration of contrast material) [ 2 ]; hemorrhagic ascites; a heterogeneous adnexal mass; lack of an intrauterine pregnancy.…”

Non-neoplastic diseases of the fallopian tube: MR imaging with emphasis on diffusion-weighted imaging

ObjectiveWe illustrate the magnetic resonance imaging (MRI) features of non-neoplastic tubaric conditions.BackgroundA variety of pathologic non-neoplastic conditions may affect the fallopian tubes. Knowledge of their imaging appearance is important for correct diagnosis. With recent advances in MRI, along with conventional MR sequences, diffusion-weighted imaging (DWI) sequences are available and may improve lesion characterization by discriminating the nature of the content of the dilated tube. Tubal fluid with low signal intensity on T1-weighted images, high signal intensity on T2-weighted images and no restricted diffusion on DWI is indicative of hydrosalpinx. Content with high signal intensity on T1-weighted images and restricted diffusion on DWI is suggestive of hematosalpinx associated with endometriosis or tubal pregnancy. A dilated tube with variable or heterogeneous signal intensity content on conventional MR sequences and restricted diffusion on DWI may suggest a pyosalpinx or tubo-ovarian abscess. We describe morphological characteristics, MR signal intensity features, enhancement behaviour and possible differential diagnosis of each lesion.ConclusionMRI is the method of choice to study adnexal pelvic masses. Qualitative and quantitative functional imaging with DWI can be of help in characterization of tubaric diseases, provided that findings are interpreted in conjunction with those obtained with conventional MRI sequences.Teaching Points• Nondilated fallopian tubes are not usually seen on MR images.• MRI is the method of choice to characterize and localize utero-adnexal masses.• MRI allows characterization of lesions through evaluation of the fluid content’s signal intensity.• DWI in conjunction with conventional MRI sequences may improve tissue characterization.• Pelvic inflammatory disease is the most common tubal pathology.
