피부염 치료를 위해 스테로이드를 처방받은 경력이 있는 11년령 수컷 시추가 비만, 얇은 피모, 복부 팽만으로 내원하였다. 방사선 사진상 폐야 전반에 기관지-간질패턴과 뚜렷한 흉막음영이 관찰되었으나 신체검사상 이와 관련한 증상은 보이지 않았다. 복부 초음파상 부신은 정상크기이며 간실질의 에코성 상승을 나타내었다. 컴퓨터 단층촬영상 폐 중앙부는 간유리음영을 나타내었으며 변연부는 중앙부에 비해 저감약성을 띄고, 고감약성 결절음영이 폐 실질전반에 산재되어 있었다. 영상진단학적 소견과 부신피질자극 호르몬 검사결과를 바탕으로 의인성 부신피질기능항진증과 속발성 폐 석회화로 진단하였다.
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.
