Findings
- High attenuation in the straight sinus and internal cerebral veins as well as throughout the superior sagittal sinus
- Hypoattenuation involving the majority of the left thalamus and extending into the genu of the left internal capsule
- Mild associated mass effect on the third ventricle
- High attenuation material within the folia of the cerebellum, particularly on the right
- Patchy subcortical and periventricular white matter hypoattenuation
Diagnosis
Dural venous sinus and deep cerebral vein thrombosis with thalamic edema and trace hemorrhage
Sample Report
High attenuation in the straight sinus and internal cerebral veins as well as throughout the superior sagittal sinus, concerning for thrombosis. Recommend brain MRI with and without contrast for further evaluation.
Hypoattenuation involving the majority of the left thalamus and extending into the genu of the left internal capsule likely represents edema/developing infarct related to venous thrombosis. Mild associated mass effect on the third ventricle without herniation or hydrocephalus.
High attenuation material within the folia of the cerebellum, particularly on the right, consistent with a small amount of likely mixed parenchymal and subarachnoid acute hemorrhage related to venous thrombosis.
Patchy subcortical and periventricular white matter hypoattenuation, which is nonspecific but may reflect sequela of chronic microvascular ischemic disease.
