Serous PFTC in a 63-year-old female, presenting with pelvic pain. a Axial T2WI through the pelvis, showing “sausage”-shaped mass (asterisk). Incomplete folds (red arrow) and the “waist” sign (white arrows), are in favour of a fallopian tube mass; b Sagittal T2WI with the same solid mass (asterisk), inside a structure with well-defined walls (white arrowhead), the “waist” sign (white arrows), incomplete folds (red arrow), and the “synechiae” sign (red arrowhead) with strands of tissue floating in the fluid-filled fallopian tube; c Coronal T2WI, with the “sausage”-shaped mass (asterisk) folded upon itself, as depicted by the portions of wall visible inside the mass (red arrow), which approximates the “spoke-wheel” sign, usually better depicted when the mass is predominantly cystic. Once again, the “synechiae” sign can be observed (red arrowhead); d T1WI, fat-saturated, post-contrast image, showing the enhancement of the solid portions of the mass. Courtesy of Dra. Rosana Santos
