Cistern5
The cerebellopontine angle is the site of the cerebellopontine angle cistern. (wikipedia.org)
The angle formed in turn creates a subarachnoid cistern, the cerebellopontine angle cistern. (wikipedia.org)
The pia mater follows the outline of the fissure and the arachnoid mater continues across the divide so that the subarachnoid space is dilated at this area, forming the cerebellopontine angle cistern. (wikipedia.org)
The coexistence of hyper-inflow aneurysms and cerebellopontine angle cistern (CPAc) arterial venous malformations (AVMs) have been rarely reported and most commonly associated with high risk of bleeding. (surgicalneurologyint.com)
27 , 29 ] Cerebellopontine angle cistern (CPAc) AVMs are even rarer,[ 32 ] especially when associated with aneurysms originating from the same parent artery (2.8-9.3% of all AVMs). (surgicalneurologyint.com)

Retrosigmoid Approach1
A retrosigmoid approach has historically been used to approach the Cerebellopontine Angle (CPA). (heraldopenaccess.us)
Cerebellum2
The cerebellopontine angle (CPA) (Latin: angulus cerebellopontinus) is located between the cerebellum and the pons. (wikipedia.org)
This fissure is made when the cerebellum folds over to the pons, creating a sharply defined angle between them. (wikipedia.org)

Tumor1
Increasing tumor volume (odds ratio [OR] 1.06, 95% CI 1.01-1.10, p = 0.009) and clival, petrous, or cerebellopontine angle location as compared with petroclival, tentorial, and foramen magnum location (OR 1.95, 95% CI 1.05-3.65, p = 0.036) were predictive of neurological decline after radiosurgery.
