Cystic Lung Diseases Flashcard

Front

Which of the following best describes cystic lung diseases (CLDs)?

Back

A heterogeneous group of pathophysiological entities comprising gas-filled lesions with imperceptible walls throughout the lung parenchyma.

Front

What is an essential tool in the evaluation of cystic lung diseases (CLDs)?

Back

High-resolution computed tomography (HRCT)

Front

Which of the following is NOT considered a pulmonary lucency separate from cysts according to the Fleischner Society criteria? Options: Fibrous wall, Pneumatoceles, Emphysema, Honeycombing

Back

Fibrous wall

Front

What is the defining feature of a pulmonary cyst as seen on radiographs or HRCT?

Back

A gas-filled round or irregularly shaped parenchymal transparency/low-attenuating area with a thin wall (<3 mm)

Front

Why is a multidisciplinary approach important in the evaluation of cystic lung diseases?

Back

Because CLDs may be associated with many different processes and require comprehensive diagnostic strategies.

Front

What is emphysema defined as?

Back

A permanent enlargement of alveolar spaces with disruption of septa and compression of surrounding parenchyma.

Front

Which of the following is NOT a form of cyst aetiology mentioned in the text?

• Check-valve obstruction by proliferation of smooth muscle cells
• Ischaemia
• Remodeling induced by matrix metalloproteinases
• Viral infection of alveolar cells

Back

Viral infection of alveolar cells

Front

Which imaging finding is associated with pulmonary fibrosis seen in severe interstitial lung disease?

Back

Honeycombing

Front

What is the main difference between cysts and other solid organs according to the text?

Back

Cysts do not develop simple structures like solid organs.

Front

Diagnostic steps for suspected lung disease?

Back

Complete history, physical examination, laboratory tests, and CXR
