title: Thrombosis of torcular herophili: diagnosis, prenatal management, and outcome.
abstract: OBJECTIVE
  The objective of this article is to describe and assess prenatal imaging findings, fetal and postnatal outcomes of thrombosis of torcular herophili, and to determine diagnostic features, pathophysiology, prognosis, and optimal management.
  
  
  METHODS
  Over a decade, we compiled the largest single-center retrospective study of outcomes. Fetal magnetic resonance imaging (MRI) was used to confirm the sonographic suspicion and monitor thrombosis of torcular herophili. We noted prenatal and postnatal imaging specifications, pregnancy outcomes, and clinical and radiological pediatric monitoring. Analysis of findings and review of the literature allowed us to define prognostic factors.
  
  
  RESULTS
  In eight cases of prenatal diagnosis of thrombosis of torcular herophili, MRI outcomes were specific. There were five deliveries at full term, two terminations of pregnancy, and one fetal demise in utero. Neonates had a good clinical and radiological outcome. Factors of poor prognosis were deep venous sinus thrombosis, enduring mass effect, brain parenchymal injury, and heart failure related to dural arteriovenous shunt.
  
  
  CONCLUSIONS
  Among dural sinus malformations, thrombosis of torcular herophili with or without extension at the posterior segment of the longitudinal sinus frequently has a good prognosis. It is urgent to wait because the prognosis can only be ascertained over time by means of ultrasound scan and MRI monitoring.
