2025年1月7日 · Pulmonary bullae (singular bulla) are gas-containing cystic structures formed by confluent destroyed and dilated airspaces (distal to terminal bronchioles).

Differentiation of a bulla from a loculated pneumothorax on a chest radiograph (CXR) can be challenging and misdiagnosis with subsequent mistreatment have been described in literature. Here we present a patient with VLS who was misdiagnosed as pneumothorax at first presentation.

3 天之前 · Bullous disease of the lungs-conventional radiograph and CT. Frontal and lateral views of the chest demonstrate numerous thin-walled, air-containing structures that represent the walls of numerous bullae. These lineal densities are characteristic for …

2025年3月25日 · On a standard chest X-ray, bullae appear as thin-walled, air-filled spaces within the lung tissue. They are typically seen as dark areas with well-defined borders. However, smaller bullae may be difficult to detect on X-rays alone, particularly if they are surrounded by normal lung tissue or obscured by other structures.

Pulmonary bullae are focal regions of emphysema with no discernible wall which measure more than 1 cm in diameter.

We emphasize how to differentiate between giant bullae and pneumothorax utilizing history, physical examination, and radiological studies, including computed tomography (CT) scan. 1. Background. The differentiation between pneumothorax and a giant bulla can be very difficult and often leads to inaccurate diagnosis and management.

2020年9月1日 · Bullous lung disease in pediatric patients is a rare entity. CT Scan of the chest provide important characteristics of the bulla and the condition of the underlying lung. Patients with Giant Pulmonary Bullae present with compressive symptoms mimicking tension pneumothorax. Bullectomy is the best option of management in patients with giant bullae.

2016年10月12日 · Bullae, cysts, and lung cavities are defined and described, including size criteria and imaging diagnosis across modality. The causes, complications, and implications of such pathology are discussed in detail. Differential diagnoses are discussed for each type of...

A pulmonary bulla is an air-filled space, greater than 1 cm in diameter, that develops within the lung due to emphysematous damage of the lung. Pulmonary emphysema itself causes destruction of the distal lung design with lasting expansion of the …

感染症之CXR 影像判讀,往往需要配合臨床病史、細菌學、以及一系列影像變化,另外注意是否有併發症。 若是單獨一次影像,無舊片可以比較,配合電腦斷層,可有較多資訊供判讀;其中: Pneumococcus, Klebsiella pneumonia, septic emboli, TB 有較特殊影像可供鑑別診斷。
