However, reports regarding <jats:italic>C. psittaci<\/jats:italic> infection-associated pancreatitis are rare. In this report, a patient with <jats:italic>C. psittaci<\/jats:italic> pneumonia complicated by acute pancreatitis is presented.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case description<\/jats:title><jats:p>The patient presented with acute upper abdominal pain and developed severe pyrexia and dyspnoea one day later. A chest computed tomography image revealed patchy consolidation in the left lung. The disease progressed rapidly, and the patient exhibited liver and kidney damage and type 1 respiratory failure within a short period of time. Metagenomic next-generation sequencing of alveolar lavage fluid revealed the presence of <jats:italic>C. psittaci<\/jats:italic>.
