What is the best approach to a cavitary lung lesion?

What is the best approach to a cavitary lung lesion?

Bottom Line. The best approach to a patient with a cavitary lung lesion includes assessing the clinical presentation and risk factors, differentiating infectious from noninfectious causes, and then utilizing this information to further direct the diagnostic evaluation.

What type of lung infection is most commonly associated with cavitating lesions on the chest radiograph?

Of these, the most common is pulmonary embolism. While pulmonary embolism is usually associated with nonspecific radiographic changes or even a normal chest radiograph (402), pulmonary infarction and necrosis may result in a cavitary lesion.

What are Cavitating lesions?

Keywords: Cavitary lung lesion, CT, Pulmonary infection, Pulmonary malignancy. A cavity is defined in the Fleischner glossary as “a gas-filled space, seen as a lucency or low-attenuation area, within pulmonary consolidation, a mass, or a nodule” [1].

What is Cavitary neoplasm?

Introduction. Cavitary lung lesions are radiologically defined as air-containing lesions with a wall within an area of a surrounding density, mass, or nodule. Cavitary Mycobacterium xenopi infection is more commonly reported in Canada, the United Kingdom, and Europe.

Which carcinoma does not cause cavitation?

Multiple cavitary lesions in primary lung cancer are rare, however, multifocal bronchoalveolar cell carcinoma can occasionally have multiple cavitary lesions (Figure 3). Small cell carcinoma is never known to cavitate.

What causes a noninfectious cavitary lung lesion?

Upon identification of a cavitary lung lesion, noninfectious etiologies must also be entertained. Noninfectious etiologies include malignancy, rheumatologic diseases, pulmonary embolism, and other causes.

Where are the cavitary lesions in the chest?

CT scan of the chest revealed multiple new cavitary lesions bilaterally with the largest lesion in the left lower lobe ( figure 3 ). Infectious diseases, rheumatology and pulmonology consultants recommended an extensive workup including mycobacterial, autoimmune, HIV and fungal tests that were negative.

How to treat cavitary lung lesions due to covid-19?

Common causes of cavitary lung lesions must be investigated appropriately in all patients. Clinicians must be aware of evolving CT findings of COVID-19 and must arrange appropriate follow-up of convalescent patients with COVID-19 to ensure complete recovery.

How are diffuse cystic and cavitary lung diseases different?

The differential diagnosis of diffuse cystic or cavitary diseases is limited compared with that of focal or multifocal involvement. Diffuse cystic disease is classically associated with 2 uncommon lung diseases, LAM and PLCH (Table 2).
