Coronal or oblique sagittal T1- weighted MR images may demonstrate neurovascular contact with or without compression of cisternal
segment of 5th cranial nerve.
However, the present and a previously reported case suggest that the absence of facial nerve symptoms, presence of large tumors extending from the geniculate ganglion to the cerebellopontine angle, and absence of contact with the cisternal
portion of the facial nerve are indicative of tumors originating from the intermediate nerve.
status had increased incidence of favourable outcome and bad cisternal
status was found to be a strong prognostic marker of mortality, (p= 0.001, OR 28.41, 95% CI, lower 12.469, upper 64.760), (Table 3).
Derived from TBI studies, perimesencephalic cisternal
compression and MLS are imaging features representing mass effect.
Classic TN is most commonly secondary to neurovascular conflict (80-90%), which refers to symptomatic compression of the cisternal
segment of CN V by an artery or less commonly a vein (6).
B-mode ultrasound images in a water bath taken vertically with the axis longitudinally through the teat canal of the total mammary cisternal
area in cows (Bos taurus L.), goats (Capra hircus L.) and sheeps were performed by Bruckmaier and Blum .
None of the cases were noted to have isolated ventricular or cisternal
lesions (Table 2).
During the cisternal
stage progressive hearing loss might be observed.
[sup], Knowledge of the anatomy of the cisterna magna, especially the key distance from skin to cisterna magna is necessary in safely performing cisternal
Another explanation could be the low proportion of cisternal
milk reported in buffalo, 95% of the milk is stored in the secretory tissue even after a milking interval of 10 to 12 hours that can only be extract with an active milk ejection .
* Segmento cisternal
: constituido por las raices emergentes del hipogloso dentro del espacio subaracnoideo entre las arterias vertebral y PICA.
However, it has been postulated that placental cysts represent massive stem villous hydrops with cisternal
formation without trophoblast proliferation.
