Fetal torcular pseudomass and development of the dural venous sinuses: insights from 2D TOF MR angiography.

Department of Obstetrics, Unidade Local de Saúde São João, Porto, Portugal.
Purpose: The described evolution in prenatal and postnatal periods appears to support the hypothesis that the torcular pseudomass (TP) is probably a physiological, highly frequent and transient developmental finding. Neverthless, it remains to be determined whether TP has any relation with the final anatomy of the adjacent venous sinuses or any anatomic variants. We aimed to explore the relation of the TP with the adjacent dural venous anatomy/anatomic variants in the prenatal period, using MR angiography (2D TOF MRA).

Background: The torcular pseudomass is an incidental extra-axial midline mass located between the venous sinuses and the occipital squama in the pediatric population. Although this structure is presumed to be a developmental feature, it has not been characterized on fetal MRI.
Objective: To determine the frequency, imaging features and longitudinal in utero evolution of torcular pseudomass using fetal MRI.
Torcular pseudomass in a 14-month-old child: illustrative case.

Departments of1Neurological Surgery and.
Background: "Torcular pseudomass," or redundant soft tissue in the torcular region, is not an infrequent incidental finding on advanced imaging of the brain in infants and young children. It was recently codified among pediatric neuroradiologists; however, its report in the pediatric neurosurgical community has not previously been elucidated.
Observations: The authors present a case of a 14-month-old child who presented with fever and a first-time seizure.
Torcular pseudomass in newborns and its association with delivery: follow up or leave it alone?
Neuroradiology

Neuroradiology Section, Department of Radiology, University of Minnesota, MMC 292, 420 Delaware St. SE, Minneapolis, MN, 55455, USA.
Purpose: The cranial epidural space (ES) is a potential space and is not generally recognized unless there is underlying pathology. With MRI in newborns, we have frequently observed T2 hyperintense thickening of the ES posterior to the confluence of sinuses, also referred to as "torcular pseudomass" (TP). We aim to identify the frequency of TP and possible associations with delivery.
