An Atypical presentation of pulmonary embolism in a critically ill patient.

A pulmonary embolism (PE) occurs when a venous thrombotic material from the lower extremities embolizes to the pulmonary vasculature. Common presenting symptoms include shortness of breath and pleuritic chest pain with vital signs demonstrating hypoxia, tachycardia, and tachypnea. In this paper, we describe a unique presentation of a critically ill patient who developed a saddle pulmonary embolism despite being on prophylactic anticoagulation.

Pneumocephalus following sneeze suppression.

Pneumocephalus is defined as air in the intracranial space. It is commonly caused by traumatic skull fractures and is diagnosed by head plain computer tomography. Treatment involves initial stabilization of vital signs and surgical intervention if symptoms do not resolve. We report a unique case of pneumocephalus following sneeze suppression.

Endovascular Repair of an Iatrogenic Pulmonary Artery Pseudoaneurysm.

Pulmonary pseudoaneurysms have various causes and typically arise from the main pulmonary artery. Surgical and endovascular options may be considered for treatment. We report the case of a man with a pseudoaneurysm arising from the right pulmonary artery, treated with a septal occlusion device and percutaneous thrombin injection. (Level of Difficulty: Advanced.).
