Heavy [T.sub.2] sequences were used to visualize cisternal
segment of the nerve which is surrounded by cerebrospinal fluid (CSF) (16).
In this case, MRI with contrast revealed the diffuse contrast enhancement in the cisternal
segment of the left oculomotor nerve.
However, when focusing on the cisternal
portion, MRI findings revealed intact facial nerve and entrapped auditory nerve.
Among all the clinical parameters, GCS on arrival and among radiological parameters Cisternal
status, Brainstem Distortion, Midline shift on CT scan showed significance, Table 3.
Follow-up diffusion MRI revealed that the extending nodular enhancements within and adjacent to the optic chiasm at the basal cisternal
level and in the leptomeningeal layers in the posterior fossa had disappeared.
B) Axial gadolinium-enhanced T1-weighted image shows enhancement within the cisternal
segment of both the vestibulocochlear nerve complex and the facial nerve.
On the other hand, perimesencephalic cisternal
compression is able to reveal mass effect in the presence of bilateral, multiple, or posterior fossa lesions; but it is at best considered semiquantitative measurement.
puncture would have been required to obtain a satisfactory specimen.
Winkels et al., "Impairment of in vivo theta-burst long-term potentiation and network excitability in the dentate gyrus of synaptopodin-deficient mice lacking the spine apparatus and the cisternal
organelle," Hippocampus, vol.
In the pons, approximately at the level of the cisternal
segment of CN V, the primary sensory nucleus mediates facial tactile sensation, and the motor nucleus innervates the muscles of the first branchial arch (Figure 1) (2).
The cranial MRI revealed diffuse thickening of the cisternal
and cavernous segments of bilateral oculomotor nerves and the cisternal
and canalicular segments of bilateral facial and vestibulocochlear nerves.
Gd-DTPA enhancement of the cisternal
portion of the oculomotor nerve on MR imaging.
The milk from the cisternal
cavity of the teat was drained out either by hand milking or by using sterile teat siphon.
This method makes it also possible to assess changes in the cisternal
size in different dairy species during lactation [2, 6, 12, 25].
