title: [Differential diagnosis problem of pulmonary changes in ulcerative colitis].
abstract: BACKGROUND
  Inflammatory intestinal diseases are often accompanied with extraintestinal and even pulmonary manifesStations. The treatment of these intestinal diseases includes sulphasalazine and mesalazine, which may have undesirable allergic and other side effects, including hypersensitive pneumonitis.
  
  
  METHODS
  Having performed colonoscopy due to abdominal pains and mushy stools, the diagnosis of ulcerous colitis was established in a 20-year-old female patient and the treatment with mesalazine initiated. However, the patient developed slimy and bloody stools, slightly increased body temperature, dry cough and bilateral lung lesions. The bronchological exploration established interstitial and organizing pneumonia. Despite the treatment with antibiotics, corticosteroids and mesalazine, dry cough, fever and bloody stools persisted, accompanied with bilateral inhomogeneous lesions of the pulmonary parenchyma. Upon discontinuation of the treatment with mesalazine, clinical symptoms and pulmonary lesions disappeared.
  
  
  CONCLUSIONS
  The differential diagnosis of pulmonary lesions in patients with ulcerous colitis may be a problem. In the reported case, pulmonary lesions were interpreted as interstitial pneumonitis accompanying ulcerous colitis. However, they are most probably a consequence of allergic response to mesalazine.
