Case ReportExam
Prior Study
There is thrombosis of the right vein of Trolard. There is hemorrhagic conversion of the thrombosed vein of Trolard producing local mass effects. There are small volume subarachnoid blood products evident within vertex sulci bilaterally and in both the suprasellar and prepontine cisterns.
No CT perfusion was available.
No CTA of the neck was available.
Findings
MRV Head
Findings are consistent with a thrombotic occlusion of mesial segment of the proximal right vein of Trolard (as it approaches the SSS). There is opacification of an ectatic, collateral pial vein located adjacent to the thrombosed Trolard vein. This collateral pial vein projects artifactually (likely from patient motion) beyond the expected brain surface.
All other veins are within normal limits. There is a variation of normal; the frontal veins course posteriorly to the frontoparietal junction bilaterallly, which leaves the frontal portion of the superior sagittal sinus hypoplastic; this does not represent segmental frontal SSS thrombosis.
Impression
2. Focal displacement of cortical veins in the right parietal vertex is related to the parenchymal hematoma associated with the vein of Trolard thrombosis.
3. Anomolous, hypoplastic frontal SSS segmental hypoplasia
