Intercostal Artery Pseudoaneurysm Due to Thoracentesis: Diagnosis With Three-Dimensional Computed Tomographic AngiographyLong, Svati Singla MD; Johnson, Pamela T. MD; Fishman, Elliot K. MDJournal of Computer Assisted Tomography: January/February 2012 - Volume 36 - Issue 1 - p 100–102 doi: 10.1097/RCT.0b013e318243250a Thoracic Imaging Abstract Author Information 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.
