Peripheral nerve sheath mass of the right trigeminal nerve Clinical and diagnostic imaging assesment JUNIOR vet dogs with cancermasticatory miositisneoplasmaotitis mediatemporal muscle atrophy Veterinary journalist Case Presentation Boxer, 8 years old, male intact, with previously diagnosis of masticatory miositis and severe unilateral temporal muscle atrophy see fig.
The major complaints were purulent discharge from the right medial orbit, seizures and vestibular symptoms. The dog had a good quality of life, normal apetite but vestibular cât de ungi dramatically increased in intensity in the last month.
The patient had rare episodes of benign cancer in golden retrievers alteration in the past. Computed Tomographic Findings Severe rightsided masticatory muscle atrophy is observed. A hyperattenuating non-uniformly enhancing mass lesion is seen within the cranial fossa dorsal to the skull base in the region of the pons. The benign cancer in golden retrievers is located to the right of the midline, it has a broad basis benign cancer in golden retrievers the underlying bone and a marked mass effect on the neighboring brain parenchyma including the pons which is displaced dorsally and to the left.
The mass can be traced through the widened hpv mouth throat cancer symptoms trigeminal canal and benign cancer in golden retrievers foramen outlet of the mandibular branch of the trigeminal nerve exiting the cranial fossa.

The right tympanic bulla is filled with uniformly hypoattenuating, non-enhancing material. There is the impression of mild generalized wall thickening which is likely to be artificial due to the point spread effect.
The inner ears are within normal limits. The nasal cavities are within normal limits. The laryngeal cartilages are partially mineralized, there is no evidence of lysis. Computed Tomographic Diagnosis Rightsided extraaxial intracranial mass in the region of the pons with extracranial extension through the passage of the trigeminal nerve mandibular branch and severe ipsilateral muscle atrophy.
Rightsided Otitis media Interpretation The computed tomographic findings are compatible with a peripheral nerve sheath tumor of the right trigeminal nerve and secondary neurogenic atrophy of the ipsilateral masticatory muscles.

Possible, but by far less likely differential diagnoses, are a lymphoma or meningioma. The findings are not typical for an abscess. The prognosis is poor.
Palliative medical treatment is recommended. Palliative radiative treatment may be an option as well but has not been evaluated for this specific indication to date.
The Otitis media is likely not infectious but due to obstruction of the right eustachian tube by the mass effect of the extracranial part of the tumor.

Follow-up Because of the poor prognosis, gradual deterioration of the quality of life with increased episodes of vestibular symptoms, the owner decide euthanasia. The necropsy was performed and the mass was prepared for histological and immunohistochemistry investigations.
Discussions Primary neoplasia of the central and peripheral nervous systems and secondary or metastatic neoplasms are commonly encountered in dogs and cats. Primary and secondary brain tumors will be considered in this chapter. Primary brain tumors can originate from brain parenchyma, the meninges, or the ependyma, as well as from vascular elements, including the choroid plexus Benign cancer in golden retrievers et al.
Peripheral nerve sheath mass of the right trigeminal nerve
Secondary neoplasms involve the giardia sintomas portugues through metastasis or by direct extension from extraneural sites. Benign and malignant tumor types exist, and the definitive cause of primary and secondary brain tumors is uncertain. Meningiomas are the most commonly reported primary brain tumors in dogs and cats and are often histopathologically benign.
In contrast to the well-encapsulated feline meningiomas, canine meningiomas tend to infiltrate the brain parenchyma, making them more difficult benign cancer in golden retrievers remove surgically. Gliomas are primary brain tumors that are reported frequently in dogs and less frequently in cats.
Dolichocephalic dog breeds e. In addition, choroid plexus tumors, primary central nervous system lymphomas, primitive neuroectodermal tumors e. Typically, the neurologic signs associated with primary brain tumors progress slowly over time; however, subacute to acute development is possible.

In approximately one half of canine primary brain tumor cases, the primary complaint is seizures. Primary brain tumor should be included as a differential diagnosis for any animal over the age of 5 years that has recent onset of seizure activity, particularly in certain benign cancer in golden retrievers e. As with any form of neoplasia, a definitive diagnosis of brain tumor cannot be made without histopathology. Since meningioma arises from the dura and results in extra-axial compression, they are typically characterized by a broad-based, extra-axial mass effect.
Additionally, meningioma typically demonstrates distinct tumor margins and uniform contrast enhancement Talarico și Dewey, The goals of palliative therapy are to reduce the secondary effects of the tumor, such as decreased peritumoral edema, and to treat seizures if present.

Most palliative therapy consists of an antiinflammatory dose of oral prednisone 0. Prednisone therapy decreases intracranial pressure by relieving tumor-associated brain edema and by decreasing cerebrospinal fluid production Dewey, If the tumor results in seizure activity, anticonvulsant drugs are also recommended.
Administration of standard phenobarbital doses in dogs with rostral forebrain tumors can lead to profound sedation Dewey, The prognosis for supportive therapy is generally considered to be poor, as many animals die or are euthanized secondary to progressive neurologic signs within 1 to 4 months Dewey, ; Heidner et al.
