Abstract

The acute onset of irreversible neurological deficit is referred to as a “stroke” and is the third leading cause of death and the major cause of adult long‐term disability in the United States. Obstruction of the venous sinuses by thrombosis accounts for ˜1% of strokes. Thrombosis of the superior saggital sinus is most frequent, with involvement of transverse, sigmoid, and cavernous sinuses occurring less often. Venous thrombosis may involve the dural sinuses, the deep venous system, and the superficial cortical veins separately or in any combination. This unit describes a for imaging dural sinuses by time‐of‐flight magnetic resonance venography (MRV).

  These authors describe the importance of MRI and MRV in the diagnosis and follow‐up of cerebral venous thrombosis. They point out how different signals on spin echo T1‐ and T2‐weighted images evolve according to hemoglobin degradation causing pitfalls and artifacts that must be recognized.

  These authors afford a current concise look at dural sinus thrombosis. In addition to imaging findings, they discuss, clinical findings, treatment, complications, pearls, and pitfalls.
