- Abstract
<bold>Objectives: </bold>We aimed to define central venous stenosis (CVS) caused by sternocostoclavicular hyperostosis as a feature of synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome on routine contrast-enhanced computed tomography (CT) images. The relationship between SAPHO syndrome and CVS without venous thrombosis caused by anterior chest wall compression has not been investigated. Therefore, the present study evaluated CVS in patients with SAPHO syndrome at our hospital.<bold>Methods: </bold>We retrospectively reviewed contrast-enhanced CT images of ten patients with suspected or diagnosed SAPHO syndrome between January 2007 and November 2015. The patients were assessed by contrast-enhanced CT using 16-, 64- or 128-detector row scanners. Two radiologists independently assessed the presence of CVS or obstruction and SAPHO syndrome in a retrospective review of CT images.<bold>Results: </bold>Six of the ten patients had findings of CVS with SAPHO syndrome. The mean diameter and patency rate at the site of CVS were 1.88 mm and 27.2%, respectively. Stenosis was more significant in terms of the mean diameter of CVS sites than of stenotic sites that crossed the anteroposterior vein (p < 0.05).<bold>Conclusions: </bold>Radiologists who routinely assess contrast-enhanced CT images should be aware that sternocostoclavicular hyperostosis with SAPHO syndrome could cause secondary CVS.<bold>Key Points: </bold>• SAPHO syndrome can cause central venous stenosis. • Radiologists should consider central venous stenosis in patients with SAPHO syndrome. • Early diagnosis of central venous stenosis due to SAPHO syndrome is challenging.
