Summary:

Description
  • Radiopaedia case ID: 38461
  • Image ID: 14674218
  • Image stack position: 31/74
  • Plane projection: Axial
  • Aux modality: DWI
  • Study description: MRI Brain
  • Study findings: A large ( 3.1 x 6.5 cm ) right temporal intraparenchymal hematoma with surrounding edema is again demonstrated. Absence of flow in the right transverse, sigmoid and imaged superior internal jugular vein is again demonstrated in keeping with venous sinus thrombosis. Interpretation of the diffusion restriction images is limited by the hematoma however the area of infarction does not appear to extend beyond the hematoma. Conclusion: Right transverse and sigmoid venous sinus thrombosis with associated venous infarct and hemorrhage again demonstrated.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: A large region of wedge-shaped hypodensity blurring the grey-white matter differentiation in the right temporoparietal region contains a moderate volume of parenchymal hemorrhage, which measures 5.8 x 3.7 x 2.7 cm. The right transverse sinus is hyperdense and shows thrombus in the venogram study. There is moderate mass effect, with effacement of the occipital horn of the right lateral ventricle, effacement of right-sided sulci and subfalcine herniation to the left of up to 5 mm at the septum pellucidum. No other regions of hemorrhage or loss of grey-white matter association. No hydrocephalus. Filling defect in the right transverse sinus, extending to the sigmoid sinus, jugular bulb and upper right internal jugular vein. The superior sagittal sinus, straight sinus and left transverse sinus opacifies normally. The deep cerebral veins also opacified normally. No skull fracture. The paranasal sinuses and mastoid air cells are clear. Conclusion: Deep venous sinus thrombosis involving the right transverse and sigmoid sinuses, extending to the jugular bulb and a right internal jugular vein. Associated venous infarct and hemorrhage.
