-To illustrate and describe cystic lung diseases through the analysis of high-resolution computed tomography (HRCT) findings. -To differentiate truecystsfrom other cyst simulating lesions.
- A lung cyst is defined as a lucency of low attenuation with a fibrous/epithelial wall.
The presence of cysts or cyst simulating entities such as emphysema,
cavitations or honeycombing can change the harmonious lung architecture,
resulting in well described patterns of diseases. - HRCT of the thorax helps to define the distribution and morphology of the cysts. - In the past decades,
due to an marked increase in the use of HRCT,
radiologists came across into incidental pulmonar cysts in...
Findings and procedure details
- HRCT is the best imaging tool to assess the size and distribution of the cysts.
Sometimes the presence of lung cysts is only part of a pathological entity whose spectrum of imaging findings is broader and more varied. - In other cases,
the presence of pulmonary cysts is of paramount importance in the definition of the underlying entity.
The latter includes Langerhans cell histiocytosis,
lymphangioleiomyomatosis and tuberous sclerosis. - When it comes to the diagnosis,
one should ask if itis...
- Lung cysts are not a rare finding and the thorough search of its shapes and distribution is required. - HRCT may be enough to reach a diagnosis and may avoid the need of a lung biopsy thus being fundamental the aknowledgement of theassociatedimaging patterns.
