Paratracheal air cysts: prevalence and relevance to pulmonary emphysema and bronchiectasis using thoracic multidetector CT.

PURPOSE We aimed to determine the prevalence of paratracheal air cysts (PTACs) and the relationship of PTACs with emphysema and bronchiectasis through retrospective analysis of multidetector computed tomography (MDCT) findings. METHODS MDCT findings of 1027 consecutive patients who underwent routine thorax examination between January 2012 and January 2013 were evaluated retrospectively for th...

An investigation into the prevalence of paratracheal air cysts revealed on multidetector computed tomography

Paratracheal air cysts (PTACs) are frequently and incidentally found on computed tomography (CT) examinations of the chest, neck, and spine. Aetiology, pathophysiology, clinical and radiological relevance, and accompanying airway and parenchymal pathologies of PTACs are not known. A limited number of studies have discussed the association between PTACs and radiological or clinical abnormalities...

Paratracheal Air Cysts: Sonographic Findings in Two Cases

We report two cases of paratracheal air cyst discovered incidentally at neck ultrasonography and confirmed at CT. The cysts were located at the inferoposterior aspect of the right lobe of the thyroid. Ultrasonography revealed an ill-defined hypoechoic mass containing hyperechoic foci which mimicked calcifications. Neck CT confirmed the presence of an ill-defined air pocket which communicated wi...
