Cerebral venous sinus thrombosis (CVST) is a rare phenomenon associated with occlusion of venous sinuses of the brain. Clinically, it presents wide variability including, headache, confusion, and stroke-like symptoms. Imaging varies from subtle findings to complex infarctions, vasogenic edema, and hemorrhages.
Herein, we report an uncommon case of CVST with visualization of the internal cerebral vein in multiphasic computed tomography angiography (MCTA).
A 76-year-old man was presented to the emergency department with a confused mentality and left side weakness. His MCTA showed no large arterial occlusion, but branches of internal cerebral veins were observed on the venous phase [Figure 1]a. On magnetic resonance imaging (MRI), diffuse hyperintensity was seen on bilateral thalamus in T2-weighted image and fluid-attenuated inversion recovery (FLAIR) [Figure 1]b. Venogram showed occlusion of the vein of Galen and straight sinus [Figure 1]c. Low-molecular-weight heparin (LMWH) was started with a dose of 1 mg/kg twice a day.

CVST is a relatively uncommon condition, representing approximately 0.5–1% of all strokes. Among them, deep CVST is even less in number. Since bilateral thalamic lesions based on MRI include a wide variety of differential diagnosis involving metabolic, infectious, and vascular disorders, early detection of CVST is difficult., However, considering the poor prognosis of deep CVST, finding an imaging marker to predict the disease holds a great clinical significance. Although genetic factors are known to be related to CVST, genetic testing is not available in all patients. Therefore, the visualization of internal cerebral veins in MCTA may play a predicting role in early diagnosis. When the deep venous occlusion occurs in deep CVST, the congestion of internal cerebral veins could be seen in MCTA. With this early predictive imaging marker, faster initiation of treatment may be expected, thus improving prognosis in deep CVST.
