Most common brain tumor in cats, typically 10 years or older. Symptoms: altered mentation, circling and difficulty walking, blindness, and seizures. MRI is needed to confirm the diagnosis and location of the tumor. Surgery is the treatment of choice for accessible tumors.
15 sie 2024 · Feline meningiomas are slow-growing tumors originating from the arachnoid layer of the meninges that surround the brain and cause compression and subsequent dysfunction of the surrounding brain tissue. There are several other differential diagnoses to consider when presented with a cat suspected to have a meningioma.
Criteria for the MRI diagnosis of meningioma have been described (Pocknell et al. 2003, Troxel et al. 2003). These are extra-axial space-occupying lesions, iso- to hyperintense signal in T2, iso- to slightly hypointense signal in T1, contrast uptake and occasionally a dural tail sign.

25 cze 2015 · The initial signs depend on where the tumor grows. If it’s over the cerebellum, for example, you would typically see a decline in muscle coordination or a head tilt. If the tumor is over the cortex, the cat might have seizures. Overall, however, the clinical signs are variable — there are no absolutely typical signs.”.
Advanced imaging techniques to diagnose intracranial meningiomas include CT and MRI. Meningiomas on CT usually present as an extra-axial, extensive contrast-enhancing mass with effect on brain symmetry.
1 maj 2012 · The diagnostic accuracy of CT in the diagnosis of feline intracranial meningiomas is unknown. In humans, the predictive accuracy of diagnosing meningiomas based on their MRI characteristics is between 65% and 96% (McDermott and Wilson, 1996, De Monte et al., 2001, Engelhard, 2001).
