Abstract :
Background
The aim of this study was to evaluate sensitivity and specificity of mediastinal sonography, and
compared with CT, in detection of anterior mediastinal neoplasms.
Materials and Methods
The sonography with convex probes (5.0 and 7.5 MHz) was done prospectively for 34 patients
(from 2 to 25 years old) with mediastinal mass. The results were compared with the results of
contrast computed tomogphy.
Results
Standard protocol of mediastinal ultrasonography showed a high diagnostic accuracy. In our
study the sensitivity of ultrasonography in detection of anterior mediastinal adenopathies in
compared with CT was 84.6% (CI95% 65.2-100). Its specificity, PPV and NPV were 90.5%
(CI95% 77-100), 84.6% and 90.5%, respectively.
Conclusion
Trasonography may have a good role in detection of anterior mediastinal
adenopathies, so that, it may be used to complement CT, and allowing a reduction of
frequency of in patients.
