CXR Spontaneous Pneumothorax
20-year-old female presents with acute left sided chest pain. She has a narrow A-P diameter exemplified in the lateral projection (below) and the asthenic build raises the suspicion for spontaneous pneumothorax. Frontal CXR shows a small subtle pneumothorax characterised by a thin pleural line and relative lucency of the left apex compared to the right

51 year old male with recent trauma with multiple rib fractures on the left resulting in flail chest. Rib fixation hardware is present on the left. Fractures are also present on the right and there are bilateral chest tubes.
A subpulmonic pneumothorax is present with the displaced pleura noted (b, white arrowheads) and the basal pneumothorax (b blue arrowhead). Note the patient is in the semi-upright position and likely more supine than upright based on the position of the pneumothorax

SLE PE Bronchopleural Fistula and Loculated Pneumothorax

24 year old male with SLE presented with chest pain and dyspnea and initial CT showed occlusive pulmonary emboli to the right lower lobe initially associated with a wedge shaped ground glass region. 2 weeks later this evolved into a bronchopleural fistula, with a loculated pneumothorax in the right lower lobe (green star in a,b,c,d).with an air fluid level (yellow arrowhead in a,c,d) and a region of compressive atelectasis (white arrowhead a,c,d).

Venous Reflux and
Benign Pneumatosis Coli

65 year old male s/p MVA presents in shock. Scout film (top left) shows left sided tension pneumothorax with rightward mediastinal shift. Axial CT through the liver (top right) shows expanded pneumothorax at the left lung base with reflux of contrast into the IVC.. Contrast also refluxes into the right renal vein (bottom left) and into the internal iliac veins (bottom right) Associated pneumatosis intestinalis in the sigmoid colon is present as well and likely secondary to the tension pneumothorax
