title: Intracranial gas: a pictorial essay.
abstract: Intracranial gas is a common finding on postcraniotomy computed tomography scans. It can also be found in a wide variety of other benign and life-threatening clinical settings. Because intracranial gas is never normal, its presence must be explained. This pictorial essay describes the imaging features of intracranial gas and demonstrates the findings for many of the causes of this condition.
