Straight sinus and internal cerebral vein thrombosis
Case contributed by:
Dr Paresh K Desai
Presentation:
Memory disturbances, diplopia. A non contrast CT revealed bilateral abnormalities. An MRI was thus performed.
Patient Data:
Age: 41
Gender: Male
Race: Indian/Pakistani
From the case:
Straight sinus and internal cerebral vein thrombosis
Modality:
MRI
MRI revealed bilateral near symmetric abnormal signal on T2 and FLAIR with punctate haemorrhages.
The T1 sagittal images in midline reveal a thrombus in the straight sinus and internal cerebral veins.
The venous thrombosis is also appreciated in Gradient echo axial images.
Case Discussion:
The occurrence of deep venous thrombosis involving the straight sinus and the internal cerebral veins is uncommon.
Bilateral symmetric basal ganglia/ thalamic hyperintensities should raise a suspicion of this entity and MR venography need to be added.
