The straight sinus will receive its major drainage from the great cerebral vein of Galen, which passes caudally under the splenium of the corpus callosum to join it. 9 The great cerebral vein of Galen joins the straight sinus at the anterior tentorial edge of the straight sinus at the level of the quadrigeminal plate 10 (Figs. The empty delta sign: frequency and significance in 76 cases of dural sinus thrombosis. Most such patients present with symptoms of elevated intracranial pressure that may rapidly escalate to a coma ( , 45 , , 46 ). 10.7–10.8). Axial T2-weighted MR image shows replacement of signal void by thrombus (arrow) in superior sagittal sinus. His body weight at birth was 2250 gm. Radiology 1987;162(3):779–785. (Long white arrows indicate superior sagittal sinus; short white arrows, straight sinus; black arrows, Rosenthal's veins). 1— 5-year-old boy with severe headache and eye pain. Pasarikovski md 1 , jerry c. The straight sinus is included with the deep cerebral veins by most authors. Case report. Summary We report findings in five patients who presented with venous thrombosis and thrombocytopenia 7 to 10 days after receiving the first dose of … The authors present a neonatal patient with straight sinus thrombosis diagnosed by PD imaging. ... Superior sagittal sinus thrombosis Cerebral venous sinus thrombosis is a rare condition when a large blood clot forms in a large vein in the brain called a dural venous sinus. He was born to an infertile mother who had received an embryo transfer. Cerebral venous thrombosis is located in descending order in the following venous structures: Major dural sinuses: Superior sagittal sinus, transverse, straight and sigmoid sinuses. Cortical veins: Vein of Labbe, which drains the temporal lobe. Fig. Inferior sagittal sinus, vein of Galen, straight sinus, right transverse sinus, and right sig moid sinus Cortical veins, superior sagittal sinus, both transverse sinuses, and left sigmoid sinus Cortical veins: Vein of Labbe, which drains the temporal lobe. Diagnosis was thrombosis of superior sagittal sinus, straight sinus, and internal cerebral veins. Thrombosis of the internal cerebral veins, vein of Galen, or straight sinus has been observed in approximately 16% of patients with cerebral venous thrombosis (, 3–, 14).
