Learning objectives To differentiate a cavity from other pulmonary lesions and describe its radiological characteristics. To review the diseases that present with cavitary lung lesions and their differential diagnosis, illustrated with cases from our hospital.
Read more Background Many diseases, both benign and malignant, can present with cavitary lung disease.Usually, a Chest Radiograph is the initial imaging technique when pulmonary pathology is suspected, with Computed Tomography (CT) being the preferred modality when a cavity is suspected.
Read more Findings and procedure details 1. INTRODUCTION AND ALGORITHMIC APPROACHA CAVITY is defined by the Fleischner Society as "a gas-filled space, seen as a lucency or low-attenuation area, within pulmonary consolidation, a mass, or a nodule ... usually produced by the expulsion or drainage of a necrotic part of the lesion via the bronchial tree". Typically, it has a wall thickness greater than 4 mm (Fig. 1 and 2). [fig 1] [fig 2] Due to the wide spectrum of clinical entities that may cause cavitary lung lesions, we should adopt...
Read more Conclusion The diagnosis of cavitary lung lesions is challenging due to their wide differential diagnosis. CT enable a detailed analysis of the radiological characteristics of these lesions.For an accurate diagnostic approach, a systematic assessment is necessary, taking into account the features of the lesion, the duration of the disease, and clinical context.
