Abstract:
Intercostal artery pseudoaneurysm is extremely rare, with only a few case reports in the literature. Presented in this case report is a patient who developed an intercostal artery pseudoaneurysm after thoracentesis for recurrent pleural effusion. Diagnosis traditionally required arteriography; however, as shown in this case, the resolution of current multidetector computed tomography scanners and the routine acquisition of isotropic data sets with 3-dimensional visualization enable identification and detailed characterization of small vascular lesions such as these.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
