A chest radiograph showed extensive left hemithorax opacification, a left apical cavitary lesion, and right apical nodular lesions.
Severe left hemithorax hypoexpansion, homolateral hemidiaphragm superelevation and presence of a large polylobulated mass, with faint enhancement and extraparietal extension.
If unrecognized and untreated, aortic dissection results in a 90% mortality with in the first 3 months, usually due to acute aortic insufficiency, major branch vessel occlusion, or rupture into the pericardium, mediastinum, or left hemithorax [10].
Sequences were divided equally between the right and left hemithorax.
Chest radiography on admission showed an opaque left hemithorax with calcified lesions in mid zone and ipsilateral mediastinal shift.
Our main objective was to evaluate the rate of correct identification (accuracy) of the presence or absence of LS in the right and left hemithorax.
Furthermore, ultrasound examination revealed a mixed echogenic mobile structure with a diameter of around 2 cm floating within the pleural fluid of the left hemithorax close to the pericardium.
Ultrasound scanning of the anterior and the lateral chest was obtained on the right and left hemithorax, from the second to the fourth fifth intercostal space from parasternal to midaxillary line.
An ultrasonography of the thorax revealed a moderate pleural effusion, irregularly thickened parietal pleura, and a mixed echogenic mobile structure of around 2 cm in diameter, floating in the pleural fluid of the left hemithorax close to the pericardium.
There was a high degree of symmetry on lung US examinations of PCP patients, while there was always differences between the right and left hemithorax among other etiologic pneumonia (P < 0.001).
Left upper lobe collapse can present as a radiographic veil-like opacity projected over the left hemithorax, this subtle opacity is a result of anterior collapse of the left upper lobe, which produces a subtle opacity rather than a sharp interface with aerated lung as the X-ray beam crosses the abnormality en face rather than tangentially (Fig. 22).
