dc.description.abstractBACKGROUND CONTEXT: Superior vena cava (SVC) obstruction can cause the development of collateral vessels. During contrast-enhanced thoracic computed tomography (CT), contrast material may reflux into the collaterals such as paravertebral venous plexus. However, an unusual pseudopathologic vertebral body enhancement on CT in the presence of SVC obstruction has not been studied previously. PURPOSE: To demonstrate clinical presentation and imaging findings of pseudopathologic vertebral body enhancement in patients with SVC obstruction. STUDY DESIGN: Retrospective study of diagnostic CT images examined at our clinic. PATIENT SAMPLE: From March, 2009 to September, 2012, a retrospective radiologic database review was performed to identify patients with obstruction of SVC causing contrast reflux into collateral vessels and presented with an unusual vertebral body enhancement on thoracic CT. Thirteen patients (11 men, mean age 51.4 years) with vertebral body enhancement were enrolled. OUTCOME MEASURES: Enhancement patterns of vertebral bodies were classified as nodular enhancement with round shape occupying less than one-third of vertebral body or polygonal enhancement occupying greater than or equal to one-third of vertebral body on axial image. The locations of enhanced areas within vertebral bodies were described using right lateral/central/left lateral, anterior/posterior, and upper/middle/lower in the x-, y-, or z-axis directions, respectively. MATERIALS AND METHODS: Enhancement patterns, locations, and the presence of a connection between vertebral body enhancement and the paravertebral venous plexus were evaluated. RESULTS: A total of 39 vertebral body enhancements were found in the 13 patients, involving cervical (n=12), thoracic (n=25), or lumbar (n=2) vertebrae. Vertebral body enhancements showed a nodular (n=19) or a polygonal (n=20) pattern. The central portions of vertebral bodies were more frequently involved. The connection to the paravertebral venous plexus was observed in 34 lesions (87.2%). CONCLUSIONS: Patients with SVC obstruction with extensive collateral vessels might exhibit a pseudopathologic vertebral enhancement. They tended to involve the central portion of the vertebral body, and most of them showed connection to the paravertebral venous plexus. (C) 2015 Elsevier Inc. All rights reserved.-
