We describe a case of cerebral deep venous and venous
sinus thromboses with anti-
cardiolipin antibody. A 62-year-old male with no previous illness of
thrombosis but with
alcohol abuse was admitted with acute onset unconsciousness. He recovered two days after with no severe sequela. Laboratory findings suggested the preceding conditions of
dehydration and
inflammation. X-ray CT of the head revealed symmetrical low density areas in the thalami and basal ganglia, high density signs in the cerebral deep veins, and dilation of the lateral ventricles. MRI on the second hospital day showed abnormal intensities in the thalami and basal ganglia (high signal on T 2-weighed and FLAIR image, low signals on T 1-weighed image, but almost isointensity on diffusion weighed image) and acute to subacute phase
thrombus in the superior sagittal sinus. Abnormal intensities observed on MRI disappeared gradually in the following studies. Venous phase images of cerebral angiography performed in chronic phase disclosed occlusion of the superior sagittal sinus and
stenosis of the vein of Galen. These radiological findings support the diagnosis of cerebral deep vein and venous
sinus thromboses. Hematological examination revealed positive anti-
cardiolipin IgG antibody. Several cases of cerebral
deep venous thrombosis with anti-
cardiolipin antibody have been reported. In our case,
dehydration induced by
alcohol abuse would have been the trigger of
thrombosis, while the existence of anti-
cardiolipin antibody might contribute to the risk of
thrombosis as an underlying condition.
