Abstract:
To evaluate the features of mediastinal tuberculous lymphadenopathy in adults on CT, especially on enhanced CT scan. Methods Seventeen patients with adult mediastinal tuberculous lymphadenopathy proved by operation, biopsy, and (or) anti tuberculous therapy were evaluated on chest film and CT scan, and 6 patients were performed with enhanced CT scan. Results The chest film finding was intrathoracic mass and (or) hilar mass only in 6 patients, but CT detected 37 enlarged nodes in all patients. Most of the enlarged nodes were located in 2R and (or) 4R (59.4%). 30 nodes (81 1%) presented as low density in the center of nodes, and there were marked enhancement at the periphery areas of the nodes after enhancement in all 6 patients (100 0%). Conclusion CT scan, especially the enhanced CT scan, is the first method of choice to diagnose the mediastinal tuberculous lymphadenopathy in adults.
