Trismus, pseudobulbar syndrome and cerebral deep venous thrombosis.

We report a case of cerebral deep venous thrombosis that manifested clinica lly by a pseudobulbar syndrome with major trismus, abnormal movements and s tatic cerebellar syndrome. To our knowledge, only three other cases of deep cerebral venous thrombosis associated with cerebellar or pseudobulbar synd rome have been published since 1985. The relatively good prognosis in our p atient could be explained by the partially intact internal cerebral veins a s well as use of early anticoagulant therapy There was a spontaneous hyperd ensity of the fair cerebri and the tentorium cerebelli on the brain CT scan , an aspect highly contributive to diagnosis. This hyperdensity of the fair cerebri was found in 19 out of 22 cases of deep venous thrombosis detailed in the literature.
