Basal Vein of Rosenthal Thrombosis-MRV
A 24 yr old female started having seizures lateralised to left side after delivery a month back. MRI brain was done which showed : edema in the right temporo-parietal region with no restricted diffusion, no post contrast enhancement.The region of edema did not conform to an arterial vascular territory. no hemorrhage was detected on GRE images. Considering classical history an MRV was done. Case Submitted by : Dr Prashant Gupta and Dr Himani Agarwal, Consultant Radiologists.
On first review all the major dural sinuses were normal. However on reviewing the source images with THICK MIP we found attenuated right deep sylvian vein and a non visualised right basal vein of rosenthal. (marked in RED).
Learning points (especially for residents)
- Look at other vessels other than major dural sinuses.
- Always review source images in thick and thin MIP in ALL planes.
- Edema not conforming to arterial territories needs a meticulous hunt for venous thrombosis, especially if the patient has a typical history.
