The aim of the work was to detect interstitial lung dis-ease at an early stage, to diagnose them correctly, to estab-lish proper treatment course and, as a result, to improve lifeexpectancy and quality in patients with this disorder.More than 200 acute and chronic conditions with inflam-matory and fibroproliferative changes consist of the groupof diffuse lung diseases. Definitive diagnosis cannot be madebased on chest X-ray only. DLD is hard to differentiate frombacterial lung diseases, such as pneumonia andtuberculosis,that frequently result in maltreatment, diseaseprogression and poor outcome. Stated factors emphasizethe importance of the issue. Professionals especially payattention to idiopathic forms of diffuse lung disease, whichis characterized by severe clinical course and poor progno-sis due to progressive fibrous processes. The right methodof approach is to exclude more common conditions, such asinfectious diseases of the lungs, structural abnormalities ofthe respiratory airway, immunodeficiencies, congenital heartdiseases, cystic fibrosis. Thus, DLD is a diagnostic chal-lenge for professional pediatricians and pulmonologists.Article presents the case report that was analyzed ac-cording to the diagnostic and management approach. It in-cludes anamnesis, clinical and diagnostic criteria of the dis-ease, established by multiple studies, different methods oftreatment
