Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
Granulomatous meningoencephalitis (GME) is an inflammatory disease of the central nervous system (CNS) of dogs and, rarely, cats.It is a form of meningoencephalitis.GME is likely second only to encephalitis caused by canine distemper virus as the most common cause of inflammatory disease of the canine CNS.

[1] [2] [3] It was originally identified and recorded in the 1960s in pure breed pugs, with which this disease is nowadays mostly associated with, occurring essentially in small breed dogs ranging from six months to seven years of age. [4] [2] [5] It causes intense necrotizing inflammatory lesions in the brain stem and Cerebellum. [3]
In most cases the cause is unknown. However, in dogs and cats it is thought to be most likely related to in utero viral infections, toxins or genetic disorders. [14] Other possible causes, if they occurred during the development period of the cerebellum and inhibit its growth, include: [15] hypoxia
Cerebellar abiotrophy (CA), also called cerebellar cortical abiotrophy (CCA), is a genetic neurological disease in animals, best known to affect certain breeds of horses, dogs and cats. It can also develop in humans. It develops when the neurons known as Purkinje cells, located in the cerebellum of the brain, begin to die off. These cells ...
Meningioma, a tumor of the meninges or membranes that surround the nerves passing through the CPA; Cerebellar astrocytoma, a malignant tumor of star-shaped glial cells called astrocytes in the cerebellum; Intracranial epidermoid cyst; Lipoma; Glomus jugulare associated with the glossopharyngeal nerve; Idiopathic hypertrophic pachymeningitis [3]
Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [ 2 ]
This may succeed or accompany temporal lobe (uncal) herniation and subfalcian herniation secondary to a supratentorial mass. [ citation needed ] The pathophysiological mechanism is uncertain [ 7 ] but is probably caused by the displacement of the brainstem stretching and tearing perforating branches of the basilar artery to the pons; venous ...
