F C Berryman, A de Lahunta

    The Cornell Veterinarian
    |April 1, 1975
    PubMed
    Summary

    A dog experienced seizures and neurological deficits, including left-sided weakness and vision loss. Post-mortem examination revealed a right cerebral astrocytoma as the cause.

    Area of Science:

    • Veterinary Neurology
    • Canine Neuro-oncology

    Background:

    • Seizures are a common neurological emergency in dogs.
    • Cerebral lesions can manifest with focal neurological deficits.

    Purpose of the Study:

    • To report a case of a canine astrocytoma presenting with specific neurological signs.
    • To correlate clinical findings with post-mortem neuropathological results.

    Main Methods:

    • Clinical examination of a dog with seizures and neurological deficits.
    • Neuropathological examination via necropsy.

    Main Results:

    • The dog presented with convulsions, left spastic hemiparesis, and partial left visual deficit.
    • Necropsy confirmed an astrocytoma in the right cerebrum.
    • The tumor was compressing critical brain structures including the internal capsule and optic tract.

    Conclusions:

    • Astrocytomas in dogs can cause focal neurological deficits mirroring the location of the cerebral lesion.
    • Clinical signs, including hemiparesis and visual deficits, are valuable indicators of underlying brain tumors.
