We reported two cases of intracranial hypertension due to superior sagittal sinus thrombosis (SSST). Case 1 was a 75-year-old male with decreased visual acuities and disturbance of visual fields in both eyes; Case 2 was a 12-year-old female with headache. Examination of both cases disclosed bilateral optic disc edemas, intracranial hypertension, and obscure flow void of superior sagittal sinus through MR imaging. Both cases were diagnosed as having SSST by MR angiography, where superior sagittal sinus was not visualized. In case 1, despite medical treatment, SSST and intracranial hypertension persisted resulting in bilateral visual loss and optic nerve atrophy. In case 2, follow-up MR angiography revealed re-established blood flow of the superior sagittal sinus. It appears that MR angiography is useful in diagnosing SSST and following up the progress of treatment.
