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. (Long white arrows indicate superior sagittal sinus; short white arrows, straight sinus; black arrows, Rosenthal's veins). Superior sagittal sinus 323 (63) Transverse sinus 290 (57) Sigmoid sinus 78 (15) Deep venous system 165 (32) Internal cerebral vein 45 (9) Vein of Galen 36 (7) Straight sinus 75 (15) Jugular bulb 43 (8) Cortical vein 30 (6) Sources.—References 3–14.

Pasarikovski md 1 , jerry c. The straight sinus is included with the deep cerebral veins by most authors. He was born to an infertile mother who had received an embryo transfer. Radiology 1987;162(3):779–785. Diagnosis was thrombosis of superior sagittal sinus, straight sinus, and internal cerebral veins. ... Superior sagittal sinus thrombosis C and D, Enhanced CT images show same structure as filling defect with enhancing rim (empty delta sign). 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. Cortical veins: Vein of Labbe, which drains the temporal lobe. 10.7–10.8). A newborn twin B was born at 34 weeks gestation. His body weight at birth was 2250 gm. Thrombosis was found in right lateral sinus (arrows).A and B, Unenhanced CT images show thrombosis as hyperdensity (dense clot sign). 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. 2—Cord sign in cortical venous thrombosis in a 1— 5-year-old boy with severe headache and eye pain. The authors present a neonatal patient with straight sinus thrombosis diagnosed by PD imaging. The empty delta sign: frequency and significance in 76 cases of dural sinus thrombosis. *Numbers in parentheses are the percentage of pa-tients. Axial T2-weighted MR image shows replacement of signal void by thrombus (arrow) in superior sagittal sinus. Fig. 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). Summary We report findings in five patients who presented with venous thrombosis and thrombocytopenia 7 to 10 days after receiving the first dose of … Most such patients present with symptoms of elevated intracranial pressure that may rapidly escalate to a coma ( , 45 , , 46 ). AJR:189, December 2007 S65 A A D B B C Fig. Case report. 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.
