| Abstract: | An 11-year-old cat with a 4-month history of lethargy, inappetence, dysphagia, partial
mandibular paralysis and weight loss, was euthanized due to the rapid deterioration of his
condition. Post-mortem radiographic examination revealed severe bone lysis of the left
zygomatic arch, temporal and parietal bones. Magnetic resonance imaging of the head showed
a large isointense mass of the left side of the skull associated with extensive lysis of
the parietal and temporal bones and destruction of the adjacent tympanic bulla. Gross and
histological examinations revealed a pulmonary adenosquamous carcinoma of the left lung,
with metastases to the spleen, liver, mesenteric lymph nodes, mesentery, diaphragm,
abdominal aorta, left orbit and calvaria. No limb or digit metastases were detected. |
