Pulmonary Infarction: Right Upper Quadrant Pain as a Presenting Symptom With Review of Typical Computed Tomography Imaging Features.

The purpose of this case presentation is to discuss right upper quadrant pain as an atypical presenting symptom in pulmonary infarction and review the typical computed tomography (CT) imaging features of pulmonary infarction to improve diagnostic accuracy. Pulmonary infarction results from occlusion of distal arterial vasculature within the lung parenchyma leading to ischemia, hemorrhage, and ultimately necrosis. Patients with lung infarction typically present with pleuritic chest pain and may have associated signs or symptoms of pulmonary thromboembolism or deep vein thrombosis.
