Herniation von Hirngewebe in durale Sinus
Brain
herniation into dural venous sinus. Nonspecific heterogeneous lesion centred within the right posterior fossa at the level of the distal transverse sinus.
Brain
herniation into dural venous sinus. MRI demostrates a polypoid cortical herniation from the lateral inferior right temporal occipital cortex into the superior aspect of the right transverse sinus in keeping with brain herniation into the tranverse sinus.
Brain

Temporal Lobe
Parenchyma Herniation into the Transverse Sinus: MRI Findings in a Case: Fluid Attenuated Inversion Recovery axial (A), T1-weighted sagittal (B), T2-weighted axial (C), contrast-enhanced T1-weighted axial (D) and sagittal (E) images show a small herniation of temporal lobe parenchyma with surrounding CSF into left transverse sinus, that was isointense to brain parenchyma on all sequences (arrows). No pathological enhancement is seen but the brain herniation sac is causing moderate stenosis in the left transverse sinus. On venography imaging (F), there was left transverse sinus stenosis but no venous thrombosis.

Brain herniation, also referred to as acquired intracranial herniation, refers to shift of brain tissue from its normal location, into an adjacent space as a result of mass effect. It is a life-threatening condition that requires prompt diagnosis.
Pathology
There are a number of different patterns of brain herniation that describe the type of herniation occurring:
- subfalcine herniation
- transalar herniation: ascending and descending
- transtentorial herniation
- downward: uncal herniation and central herniation
- upward: ascending transtentorial herniation
- tonsillar herniation
- extracranial (transcalvarial) herniation
- paradoxical brain herniation
Etiology
Any intracranial mass can have this effect:
- intracranial hemorrhage
- cerebral swelling
- cerebral infarction
- peritumoural or periabscess edema
- tumors
- brain tumors
- meningioma
- base of skull tumors
- suprasellar tumors
- cerebral abscess
