Diagnosing high intracranial pressure by clinical and diagnostic imaging is particularly challenging for chronic or slow-growing lesions. The aim of this prospective case-control study is to determine whether the neuroscore and brain magnetic resonance imaging (MRI) are related to the direct measurement of intracranial pressure in sheep affected by intracranial slow-growing lesions due to chronic cerebral coenurosis (Coenurus cerebralis). Seventeen affected and 10 control sheep were included…

Repeatability of ultrasound examination of the optic nerve sheath diameter in the adult cat: comparison between healthy cats and cats suffering from presumed intracranial hypertension
TLDR
The transpalpebral ultrasonographic technique is a non-invasive, feasible and reproducible method to measure ONSD both in healthy cats and in cats suffering from suspected ICH.
The Translational Benefits of Sheep as Large Animal Models of Human Neurological Disorders
TLDR
An overview of the benefits of using sheep to model neurological conditions is provided, and naturally occurring and experimentally induced sheep models that have demonstrated translational validity are highlighted.
Taenia multiceps coenurosis: a review
TLDR
The best diagnostic method for cerebral coenurosis involves the interpretation of clinical signs with accurate localization of the cyst using diagnostic imaging techniques, and a vaccine based on recombinant oncosphere antigens has proved to be an effective tool against T. multiceps infection in sheep.

Magnetic resonance imaging of the brain and skull of sheep with cerebral coenurosis.
TLDR
It is suggested that cranial cavity volume and morphological abnormalities can be detected in sheep with CC, which may reflect abnormalities in ossification of the cranial bones secondary to chronically increased ICP caused by development of T multiceps cysts.
T2-weighted magnetic resonance imaging measurements of optic nerve sheath diameter in dogs with and without presumed intracranial hypertension.
TLDR
It is indicated that the ratio of MRI optic nerve sheath diameter relative to body weight may be a repeatable predictor of intracranial hypertension in dogs.
Clinical and Diagnostic Imaging Features of Brain Herniation in Dogs and Cats
TLDR
Brain herniation can be quantified on MRI and more severe CTH based on TTX is associated with a worse short‐term outcome, compared with more severe foramen magnum based on FMH.
Clinical evolution of cerebral coenurosis from invasive to chronic infection in sheep and a goat.
TLDR
MRI captured the transition between the invasive and quiescent phase of the infection, revealing the concurrent presence of meningitis and small cysts in small ruminants.
Evaluation of an acute focal epidural mass model to characterize the intracranial pressure-volume relationship in healthy Beagles.
TLDR
Characterization of the intracranial pressure-volume relationship (ICPVR) in dogs by use of an acute frontal-parietal mass lesion model may provide clinically useful information regarding the safety of obtaining CSF from the atlanto-occipital space or implantation of brachytherapy catheters and for determining the need for decompressive craniectomy in dogs with acute intrac Cranial disease.
Monitoring and interpretation of intracranial pressure
TLDR
Information which can be derived from ICP and its waveforms includes cerebral perfusion pressure (CPP), regulation of cerebral blood flow and volume, CSF absorption capacity, brain compensatory reserve, and content of vasogenic events allow prediction of prognosis of survival following head injury and optimisation of “CPP-guided therapy”.
Magnetic resonance imaging of the canine optic nerve.
We describe the magnetic resonance (MR) imaging aspects of normal canine optic nerve, the diameter of the optic nerve as measured on MR images, and optimal MR sequences for the evaluation of the
Cisternal cerebrospinal fluid analysis in 24 sheep with chronic coenurosis.
TLDR
Coenurosis, a neurological parasitic infection of ruminants caused by the larval stage of Taenia multiceps, is commonly reported in Sardinia, the most representative region for ovine population in Italy and the very absence of significant neutrophilic pleocytosis could be considered useful to diagnose chronic cerebral coenurosis.
