Prenatal demonstration of afferent vessels and progressive thrombosis in a torcular malformation

Abstract

The vascular malformation had a fixed volume and preceded the thrombosis, which formed within several days. The present case is the first report with all the prenatal sonographic features of this condition.

Thrombosis of torcular herophili: diagnosis, prenatal management, and outcome

“…There are about 40 cases of prenatally diagnosed thrombosis of the torcular herophili in the literature (case reports [3][4][5][6][7][8][9][10] and case series [11][12][13][14][15][16] ). We present a series of eight cases, the largest single-center series yet reported.…”

Prenatal Diagnosis of an Isolated Dural Sinus Malformation With Thrombosis

“…Termination of pregnancy took place in 7 of 22 cases, of which in 4 cases the prognosis was unpredictable; in one case, sonography showed enlargement of the mass and the surrounding fluid with increased compression on the posterior fossa and the brain system, 5 and in the fifth case, color Doppler imaging revealed vascular flow within this lesion 8 . One infant died postnatally after surgical management, and another died in the fourth postnatal month; in that case, a painful lambdoid tumor was diagnosed.…”

Thrombosis of an Ectatic Torcular Herophili: Anatomic Localization Using Fetal Neurosonography

“…In addition, Grange et al 5 recently reported progressive formation of a thrombus in a dilated torcular. The authors concluded that a primary venous malformation led to aberrant flow and progressive clot formation.…”

“…Several authors have published their experience in using magnetic resonance imaging (MRI) to aid in the diagnosis. [1][2][3][4][5][6][7] We describe how dedicated 2-dimensional (2D)/3-dimensional (3D) neurosonography with power Doppler imaging accurately diagnosed this lesion in the third trimester. In addition, we present the findings of the pathologist's examination, which may shed light on the pathophysiologic mechanisms of this lesion.…”

“…Fetal MRI is often used to confirm the diagnosis. [1][2][3][4][5][6][7][8] The authors of the largest series of antenatal cases (n = 13) believe that "the characteristic dural location . .…”
