Two dogs, a 14‐year‐old, female American Eskimo dog and a 14‐year‐old, male Maltese dog, were presented with thalamic syndromes, including lowered levels of consciousness, poor postural responses and presence of masses in the neck region. In both dogs, magnetic resonance imaging revealed multiple masses inside the cranium, including the pituitary gland. One dog died from status epilepticus two days after magnetic resonance imaging and the other died two months after magnetic resonance imaging from respiratory failure. These dogs were histopathologically diagnosed with multiple metastases of thyroid cancer occurring inside the cranium, including the pituitary gland. To the authors’ knowledge, this is the first time this tumour pattern has been reported in dogs, but it is possible that it is not uncommon.
