Table 1 Sonographic and CT features in the differential diagnosis of fallopian tube torsion

From: Isolated fallopian tube torsion: a rare diagnosis in a perimenopausal patient with adnexal mass and raised Ca 19-9

Features

Ultrasound/Doppler

  Thickened walls of a distended fallopian tube with thickened fimbriae and the presence of internal debris within the tube [10]

  Unilateral high impedance flow with reversed diastolic flow or absence of blood flow to the twisted adnexal [10, 11]

CT

  Tubal thickening defined as tubal diameter >15 mm [12]

  Tubal hemorrhage defined as density >50 HU on unenhanced examinations [12]

  Thickened broad ligament associated with inflammatory changes [13]

  Cystic mass of tubular configuration with tubular thickening and free peritoneal fluid [10]
