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...
متن کاملIncidental Paratracheal Air Cysts on Thoracic CT and Their Association with Chronic Inflammatory Lung Disease
Purpose. To determine the association between the progression of upper lung fibrosis and paratracheal air cysts (PACs) size. Materials and Methods. The thoracic CT images of 4573 patients were reviewed for the prevalence, size, and location of PACs and their communication with trachea. In addition, the presence of upper lung fibrosis, emphysema, and bronchiectasis was evaluated in patients with...
متن کاملVoice Change Due to Paratracheal Air Cysts
Paratracheal air cysts are a rare entity in which cystic formation occurs adjacent to the trachea. Most patients with paratracheal air cysts are asymptomatic, and the cysts are detected incidentally on chest radiograph or computed tomography (CT) scan. Most symptomatic patients complain of pulmonary symptoms or repeated respiratory infection. Rarely, the air cysts can lead to paralysis of the r...
متن کاملAn 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...
متن کاملParatracheal 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...
