Abstract
A 4-year-old, 3.5-kg, entire male cat was presented with severe lethargy and increasing dyspnoea and respiratory distress, nasal discharge, excessive salivation, loss of appetite and weight loss, over the past few days. He was an indoor-outdoor cat and was fed a homemade diet.
 On physical examination, severe laboured abdominal breathing, nasal discharge and excessive salivation were evident. Mucous membranes were slightly hyperaemic, with no jaundice or cyanosis observed. There was no jugular distension. Gingival capillary refill time was 2 seconds. Body temperature was 39.2 °C. On palpation, the mandibular lymph nodes were mildly enlarged, while no abdominal mass was detected. On thoracic auscultation, bronchial crackles in the right lung lobe and dysphonia in the left lobe were noted. The cat was initially stabilised with oxygen therapy (10 L/min) by oxygen chamber. Venous blood (jugular venepuncture), urine (mid-stream free-flow) and faecal samples (rectal swab) were taken for laboratory analysis. Abdominal ultrasonography, thoracic and abdominal radiography, and thoracic computed tomography (CT) were performed.
Highlights
Accompanied by necrotic areas and Cryptococcus, and it was concluded that the management protocol which was performed in the present case would be beneficial for clinicians
A definitive diagnosis of a diffuse granulomatous pneumonia with severe mediastinal shift caused by pulmonary Cryptococcosis was established based on clinical, laboratory and necropsy findings
Since the mediastinum is in contact with the facial surfaces of the neck and retroperitoneal space, pneumomediastinum, diaphragmatic hernia, pleural effusion, atelectasis and masses can be detected in the presence of mediastinal shift (Blaxter, 1986; Cohn 2009)
Summary
Accompanied by necrotic areas and Cryptococcus, and it was concluded that the management protocol which was performed in the present case would be beneficial for clinicians. Based on the pulmonary imaging findings, differential diagnoses considered were focal pneumonia, granulomatous lesions, primary or metastatic lung tumors. A definitive diagnosis of a diffuse granulomatous pneumonia with severe mediastinal shift caused by pulmonary Cryptococcosis was established based on clinical, laboratory and necropsy findings.
