Magnetic resonance images of a case of superior sagittal sinus thrombosis before and after complete recanalization are presented. The patient was a 61-year-old man with two days history of intermittent right hemiconvulsion followed by post-ictal hemiplegia. Mild erythrocytosis was noted on admission. CT scans revealed left frontal hemorrhagic infarction with empty delta sign in the middle portion of the superior sagittal sinus. Left carotid angiogram showed occlusion of two frontal cortical veins and retrograde filling of these veins into the cavernous sinus. Lack of filling of the middle and anterior part of the superior sagittal sinus was noted. These studies led to the diagnosis of superior sagittal sinus thrombosis associated with hemorrhagic infarction. He was treated with intravenous infusion of low molecular dextran and venesection. Neither heparin, urokinase, hyperosmolar solutions nor steroids were used because of the presence of hemorrhagic infarction and of the lack of signs of increased intracranial pressure. He completely recovered neurologically and recanalization of the superior sagittal sinus was confirmed angiographically eight weeks after the onset. Magnetic resonance images were taken with a Siemens 1.5 T Magnetom scanner using spin-echo pulse sequences. A T 1-weighted mid-sagittal magnetic resonance image ten days after the onset showed hyperintensity in the middle part of the superior sagittal sinus which corresponded to the thrombus. Both T 1 and T 2 weighted coronal images revealed a small area of hypointensity indicating the existence of residual blood flow in the superior sagittal sinus in addition to the thrombus both in the sinus and in the cortical vein.(ABSTRACT TRUNCATED AT 250 WORDS)

A 59-year-old man had suffered from consciousness disturbance and right hemiplegia in December, 1996. He was diagnosed as left putaminal hemorrhage and his symptoms improved by conservative treatment. After one week since the onset, when he became alert, he noticed deafness. He was admitted in our hospital because of deafness and dysarthria in March, 2001. T 1-weighted MR image of the brain revealed bilateral putaminal hemorrhage and a low signal area in the white matter of right temporal lobe. Single photon emission computed tomography image revealed hypoperfusion in the bilateral temporal lobes. His electrocochleogram and auditory brainstem response were normal. Audiogram revealed increased air and bone conduction thresholds. Therefore, we diagnosed his condition as cortical deafness. He could only recognize loudness as the sound by the electrical promontory test. These results indicate that his cortical deafness might be caused by his bilateral acoustic radiation damage associated with the right partial temporal lobe damage and that some fibers of the acoustic radiation, which were responsible for the recognition of loudness of sound, were spared. Therefore he has a possibility of regaining hearing capability by a cochlear implant.
