Sequence of Rare Diagnoses in a Young Patient: Altitude Barotrauma Hemopneumothorax and Desquamative Interstitial Pneumonia.

We present the case of a 35-year-old patient without pathological history who developed hemopneumothorax due to altitude barotrauma during a commercial airline flight. The computed tomography (CT) of the chest identified the presence of right hydropneumothorax and emphysema "blebs" and bubbles. After the therapeutic insertion of a drain tube, the patient returned to the country by land transport. Three weeks later, he was diagnosed with right-sided pleurisy based on a CT scan with contrast material. A surgical intervention was then performed, and three biopsy samples were taken; the histopathological result highlighted suggestive elements for the diagnosis of desquamative interstitial pneumonia (DIP).

Hepatopulmonary syndrome: an unusual cause of dyspnea in the pulmonology ward - case presentation.

Hepatopulmonary syndrome is one of the possible complications of chronic liver disease, defined clinically by impaired oxygenation. The underlying cause of the respiratory failure is the presence of intrapulmonary shunting, as a result of abnormal vascular dilatations in the lungs. We report the case of 52-year-old male, exsmoker, with a history of pulmonary TB and also of heavy drinking, who was admitted to the pulmonology ward for dyspnea at rest and limb cyanosis. His clinical exam was suggestive of liver cirrhosis, with signs of pneumonia, but also chronic lung disease. Variations in SaO2 with posture were noted: platypnea and orthodeoxia. Arterial gas assessment revealed severe hypoxemia, only partially corrected by high-flow oxygen therapy, while plethysmography showed only a mild obstructive syndrome, but with severely impaired alveolar-capillary diffusion. The suspicion of a hepatopulmonary syndrome was raised and a contrast echocardiography confirmed the diagnosis by revealing the presence of an intrapulmonary shunt. Although it is believed to be a fairly common complication of chronic liver disease, it is possible for a case of hepatopulmonary syndrome to be admitted solely for respiratory symptoms. The patient's poor socio-economic status is the main reason for both the lack of proper followup for his liver disease and the limited therapeutic options.
