White Out

 

Lung Cancer, Tension Hydro/Hemothorax, and Atelectasis
85-year-old female with a history of lung cancer, presents with a dyspnea and hypotension. CXR shows “white out” of the right hemithorax with pressure effect characterised by narrowing of the distal trachea cardio-mediastinal shift and atelectasis in the left lower lobe. The lateral examination shows silhouetting of the right hemidiaphragm.

Lung Cancer, Tension Hydrothorax, and Atelectasis
85-year-old female with a history of lung cancer, presents with a dyspnea and hypotension. CT scan shows a large right pleural effusion under pressure, with mediastinal shift to the right. In addition, there is compression of the heart with back up of venous return due the pressure effect on the heart and vascular structures. Among the structures showing venous distension are the SVC (blue arrowhead, a) right sided upper limb veins (blue arrowhead b) and the left upper pulmonary veins (red arrowhead, b. The effusion in the right pleural cavity with atelectatic lung herniates into the left hemithorax, (white arrowhead, c). There is a dense sediment in the pleural fluid (red arrowhead, d) suggesting blood in the pleural cavity. The left atrium is compressed (maroon arrowhead, d)

Occluded Main Stem Bronchus, Atelectasis of the Right Lung, and Pleural Effusion
59F shows total white out caused by collapse of right lung with an
occluded right main step bronchus associated with a
large right sided effusion. The occlusion is likely due to proximal cancer. A pigtail drain has been placed to drain the effusion

Occluded Main Stem Bronchus, Atelectasis of the Right Lung, and Pleural Effusion
59F shows total collapse of right lung with an
occluded right main step bronchus(top right image)associated with a
large right sided effusion. The occlusion is likely due to proximal cancer

Left Lung Collapse and Large Effusion s/p Stent
82-year-old female with dyspnea presents with an obstructing lesion of the left main stem bronchus and total atelectasis of the left lung and associated effusion. White out of the left lung with mediastinal shift are noted on the scout film (top left) and the axial images confirm complete collapse of the left lung with a large effusion. A proximal malignancy was found, and the left mainstem bronchus stented, unsuccessfully.

  • Left Lung Collapse From a Mucus Plug

    68 year old ICU patient has an Xray at 2:30pm to check tube position .  4 hours later he presents with a acute respirtatory difficulty and the re is a white out of the left lung (middle image).  After suction, a repeat CXR approximately 2 hours later shows improving aeration.  The rapid response to suction usually infers obstruction from  a mucus plug or inhalation of a foreign body with removal .
