An adult female hyacinth macaw (Anodorhynchus hyacinthinus) was presented for sudden onset of severe weakness in the legs. Neurologic examination revealed bilateral paresis of the pelvic limbs and decreased proprioception. Results of radiographs and computed tomography (CT) revealed variably sized soft tissue nodules throughout the lungs and invading into the spine and vertebral canal. Soon after the CT scan, the bird went into cardiorespiratory arrest and died. At necropsy, several yellow, coalescing nodules that were firm with a caseous component were present in the lungs, and a focus of similar tissue was attached to the vertebrae and invaded the spinal canal. On histologic examination, the diagnosis was primary pulmonary bronchial adenocarcinoma with spinal invasion.
