A 7-year-old, spayed female Chihuahua with dyspnea, intermittent cyanosis, and dermal plaques was diagnosed with hyperadrenocorticism. Thoracic radiographs showed markedly hyperdense alveoli in multiple lung lobes. Computed tomography (CT) images showed lung mineralization confined to the lung parenchyma and pituitary macroadenoma. Pulmonary mineralization secondary to hyperadrenocorticism is commonly found on histopathologic examination. However, those lesions are rarely identified radiographically. We describe obvious pulmonary mineralization secondary to hyperadrenocorticism found on radiographs and present the first report regarding CT imaging of the mineralization. Pulmonary mineralization should be considered when a dog affected by hyperadrenocorticism shows diffuse lung mineralization on radiographs.

An 11-year-old, intact male Shih Tzu presented with obesity, thin hair coat, and abdominal distention. The patient had previously received corticosteroid therapy for dermatitis. Thoracic radiographs showed incidental findings of a generally diffuse bronchointerstitial pattern and markedly radiolucent pleural lines between the middle and caudal lung lobes, but clinical signs related to the thoracic radiographic findings were absent. Echogenicity of the hepatic parenchyma was increased and bilateral adrenal glands were not enlarged on ultrasonography. On computed tomography, the central regions of the lung lobes showed ground-glass attenuation, the peripheral regions of the lung lobes were relatively hypoattenuated compared with the central regions, and hyperattenuated nodules were distributed throughout the pulmonary parenchyma. Iatrogenic hyperadrenocorticism and secondary pulmonary mineralization was diagnosed on the basis of diagnostic imaging and adrenocorticotropic hormone stimulation test.
