2024年1月15日 · The ambient cistern is a thin, sheet-like extension of the quadrigeminal cistern that extends laterally around the midbrain and posterior to the thalami. It acts as the connection between the quadrigeminal cistern and the interpeduncular cistern.

2025年1月29日 · The subarachnoid cisterns, or basal cisterns, are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: "box"). As they are interconnected, their patency is essential for CSF circulation.

2024年8月11日 · An annotated MRI brain depicting the subarachnoid cisterns: Lateral Ventricle: Within cerebral hemispheres. Third Ventricle: Between thalami. Fourth Ventricle: Between brainstem and cerebellum. Cisterna Magna: Cerebellum and medulla oblongata. Prepontine Cistern: Anterior to pons. Cerebellopontine Cistern: Cerebellum and pons

2025年1月1日 · The ambient cistern is a noncommunicating paramedian dorsal paired cistern according to the Liliequist classification. While the ambient wing cistern is described for the first time in 1875, Key and Retzius and firstly named in 1950 by Dr. Bengt Liliequist (1923–2008).

Each of three separate anatomic segments of the ambient cistern — the supratentorial segment, the tentorial edge and the subtentorial segment — has a characteristic CT appearance that can be correlated with specific vascular structures on routine angiography.

The cisterna ambiens (ambient cistern) (Figures 11A-11D) is surgically significant as it is situated along the lateral aspect of the brain stem (arrows in Figures 11B, 11D) with both supratentorial and infratentorial extensions.

The angiographic and high-resolution, thin-section CT appearance of the normal ambient cistern is correlated with anatomic dissections and sections of normal, formalin-fixed cadaver brains. Each of three separate anatomic segments of the ambient cistern--the …

1985年2月1日 · The ambient cistern is located above the perimesencephalic membrane and contains the anterior choroidal arteries, the posterior cerebral arteries, the basal vein, and sometimes the segments of...

Ambient cistern (AC) is a thin extension of the subarachnoid space surround-ing the brainstem at the level of the mesencephalon and pons. Despite various definitions, it constitutes an important landmark in clinical assessment of in-tracranial volume reserve.

A combination of computed tomography and angiography permits accurate detailed evaluation of common lesions of the ambient cistern. Article PDF Download to read the full article text
