Skeletal Radiol 2024; 53:1507-1515. [PMID: 38363418 PMCID: PMC11194195 DOI: 10.1007/s00256-024-04609-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 01/30/2024] [Accepted: 01/30/2024] [Indexed: 02/17/2024]
Abstract
OBJECTIVE To investigate the CT features of incidental rib enhancement (RE) and to summarize the CT characteristics for distinguishing the RE from sclerotic metastasis (SM) in patients with malignancies. MATERIAL AND METHODS This retrospective observational study enrolled 79 patients with RE (involved 133 ribs) during October 2014 and December 2021. Another 53 patients with SM (160 SM) in the same period were selected randomly for comparison. The location, enhancement patterns of RE were reviewed. The CT values of RE regions and SM were measured and statistically analyzed. RESULTS Most REs (70 patients, 88.6%) were in the 1st to 6th ribs. 50 patients had solitary RE and 29 with multiple REs in a regional distribution. All the REs were closely connected to the intercostal venous plexus (ICVP) ipsilateral to the injection site. No visible abnormalities on unenhanced scans were detected in all REs. One hundred and twenty REs (90.2%) had nodular/patchy enhancement. The CT value of RE regions in the venous phase was lower than that in the arterial phase (589.8 ± 344.2 HU versus 1188.5 ± 325.3 HU, p < 0.001). During the venous phase, most REs (125, 94.0%) shrank or disappeared. SM appeared similar on both contrast-enhanced and unenhanced scans in terms of shape and CT values. CONCLUSION The RE demonstrated characteristic CT features. The manifestations of nodular/patchy enhancement in the arterial phase, decreased density and shrinkage or disappearance during the venous phase, and no abnormality on unenhanced scans, as well as a close connection with the ICVP, may help differentiate RE from SM.

Abstract
Superior vena cava (SVC) syndrome comprises a constellation of clinical signs and symptoms caused by obstruction of blood flow through the SVC. The management of patients with life-threatening SVC syndrome is evolving from radiation therapy to endovascular therapy as the first-line treatment. There is a paucity of data and societal guidelines with regard to the management of SVC syndrome. This paper aims to update the practicing interventionalists with the contemporary and the evolving therapeutic approach to SVC syndrome. In addition, the review will focus on endovascular techniques, including catheter-directed thrombolysis, angioplasty, and stenting, and their associated complications.

Abstract
Superior vena cava syndrome (SVCS) often relates to malignant causes such as lung tumors, metastatic cancer, or lymphomas. While the diagnosis relies nowadays on the use of contrast-enhanced thoracic computed tomography, ultrasonography may have an important value as a first-line imaging technique, particularly when used in point-of-care office-based settings. Here, we report the case of a 67-year-old male presenting with SVCS in whom ultrasound contributed to diagnosis.
