Torsion tubaire isolée : ne ratons pas le diagnostic ! À propos de deux cas pédiatriques

Isolated torsion of the fallopian tube is a little-known pathology, which takes place in the differential diagnosis of lower abdominal pain in women. Rapid radiological diagnosis allows an adequate surgical management and higher rate of revascularization of the fallopian tube. Ultrasound is the first choice to rule out an acute abdominal pain in case of emergency in young women. Although rarely used in emergency but increasingly available, MRI could be a second relevant non-irradiating imaging method to confirm the diagnosis of tubal twist in pediatrics. In this article, we present two cases of isolated tubal twist in which the echographic signs of tubal torsion and the contribution of the MRI to confirm the diagnosis are shown. The clinical features of an isolated tubal torsion are not specific. In our two cases, the diagnosis was suspected by ultrasound and confirmed by magnetic resonance imaging (MRI). By its high contrast resolution and 3D-resolution, MRI can lead to the diagnosis with a high degree of certitude. Pathognomonic radiological features in tubal twists are the “beak sign” and the “whirlpool sign”. Regardless of the stage of necrosis, a detorsion should be performed. The functional prognosis of the tube after detorsion has not been studied.
