Dural sinus thrombosis is a diagnosis that is not commonly thought of in the first instance by radiologists and clinicians, especially when the clinical presentation is not specific. We describe the clinical presentation of three patients with acute thrombosis of the superior sagittal sinus, the left transverse sinus, and the right cavernous sinus, respectively. Compared with computed tomography, magnetic resonance imaging is more diagnostic of this condition. Magnetic resonance venography may not be necessary for the diagnosis of acute dural sinus thrombosis, but is helpful in cases of cortical or deep vein thrombosis and chronic thrombosis.
