Introduction:
Mediastinal syndrome is suspected on the basis of clinical symptoms and is generally confirmed by chest radiography or computed tomography (CT). However, also grey scale ultrasound (US) and contrast enhanced US (CEUS) are useful in this hematologic emergency as they provide the possibility to perform US-guided biopsy and histological diagnosis.
Materials And Methods:
15 Patients affected by mediastinal syndrome were prospectively studied using B-mode US and CEUS; 13 of these patients, who had no other lesions, were proposed for US-guided biopsy of the mediastinal mass, but only in 12 patients biopsy was technically possible.
Results:
In this study, B-mode US reached an excellent sensitivity (100%) in evidencing the lesions but a low specificity which did not exceed 30-40%. CEUS reached an elevated specificity identifying neoplastic pathologies if both the early and the late phases are considered (90-86.6%). US-guided biopsy was possible in 92.3% of lesions showing a diagnostic adequacy of 91.66%.
Conclusions:
B-mode US associated with CEUS and US-guided biopsy reached an elevated accuracy in the diagnosis of mediastinal masses. If these results are confirmed by further studies, this diagnostic procedure could be included in the routine management of mediastinal syndrome.
