“…The most common of these rare disorders are PLCH and lymphangioleiomyomatosis. Less common causes include Pneumocystis jiroveci pneumonia, Birt–Hogg–Dubé syndrome, lymphocytic interstitial pneumonia, and amyloidosis [ 1 , 2 ]. HRCT is the most important diagnostic modality in PLCH [ 3 ], suggesting the diagnosis and displaying different stages of disease.…”

Pulmonary Langerhans cell histiocytosis (PLCH) affects mainly young, predominantly smoking adults with a peak at 20–40 years of age. Patients with PLCH often present with a nonproductive cough and/or dyspnea. High-resolution CT (HRCT) is the most important diagnostic modality in PLCH. The typical HRCT pattern combines small poorly limited nodules, cavitated nodules, and finally thick- and thin-walled cysts. In rare cases, HRCT enables PLCH to be diagnosed prior to the development of cysts.

“…HRCT produces images of great clarity and detail in different orientations, and is critical in the diagnostic evaluation. 2,3 In this regard, obtaining contiguous 1 or 1.5 mm sections using an edge-enhancing algorithm throughout the thorax in a single breath-hold is essential. This will precisely define the walls, extent and distribution of lucent lung lesions, and also generate high qualitycoronal and sagittal image reconstructions.…”

Cysts are commonly seen on CT scans of the lungs, and diagnosis can be challenging. Clinical and radiographic features combined with a multidisciplinary approach may help differentiate among various disease entities, allowing correct diagnosis. It is important to distinguish cysts from cavities because they each have distinct etiologies and associated clinical disorders. Conditions such as emphysema, and cystic bronchiectasis may also mimic cystic disease. A simplified classification of cysts is proposed. Cysts can occur in greater profusion in the subpleural areas, when they typically represent paraseptal emphysema, bullae, or honeycombing. Cysts that are present in the lung parenchyma but away from subpleural areas may be present without any other abnormalities on high-resolution CT scans. These are further categorized into solitary or multifocal/diffuse cysts. Solitary cysts may be incidentally discovered and may be an age related phenomenon or may be a remnant of prior trauma or infection. Multifocal/diffuse cysts can occur with lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, tracheobronchial papillomatosis, or primary and metastatic cancers. Multifocal/diffuse cysts may be associated with nodules (lymphoid interstitial pneumonia, light-chain deposition disease, amyloidosis, and Langerhans cell histiocytosis) or with ground-glass opacities (Pneumocystis jirovecii pneumonia and desquamative interstitial pneumonia). Using the results of the high-resolution CT scans as a starting point, and incorporating the patient's clinical history, physical examination, and laboratory findings, is likely to narrow the differential diagnosis of cystic lesions considerably.

“…63 The Fleischner Society describes honeycombing as clustered cystic air spaces, typically of comparable diameters of the order of 3 to 10 mm but occasionally as large as 2.5 cm. 64 Honeycombing is typically subpleural in distribution.…”
