Introduction: Mediastinal lymphadenopathy is expected to be the common mediastinal masses because this is caused by high prevalent diseases like tuberculosis, lung cancer metastasis, lymphoma and sarcoidosis etc. Mediastinal lymphadenopathies are difficult to biopsy since they are nearer to major vessels and airways and located commonly in the middle compartment. Hence mediastinal lymphadenopathy is under represented in many studies since unable to obtain tissue diagnosis. The newer techniques EBUS and EUS are made easier to approach the mass like lymphadenopthy in middle mediastinum with less complication. Objective: To know the effectiveness of real-time EBUS in the evaluation of mediastinal lymphadenopathy. Methodology: In our study 50 cases of mediastinal lymphadenopathy diagnosed by CT scan chest which were subjected to EBUS guided real time TBNA of mediastinal nodes. TBNA Specimens were sent for histopathological examinations and reports were collocated and analyzed. Results: Among 50 cases of mediastinal lymphadenopathy, arrived diagnosis in EBUS TBNA in 42 cases and inconclusive results in other 8 cases. Among 42 cases, tuberculosis in 17 cases [34%], malignancy in 16 cases [32%], sarcoidosis in 8 cases [16%], sub acute inflammation in 1 case [2%]. Conclusion: Before the advent of EBUS, Percutaneous transthoracic needle biopsy/FNAC (under CT or ultrasound guidance) or surgical procedures [VATS or Mediastinoscopy] were considered as the initial method of choice in evaluation of mediastinal lesions. EBUS techniques has demonstrated utility in the diagnosis of mediastinal lymphadenopathy secondary to malignancy, tuberculosis and sarcoidosis and easier and lesser complication than more invasive procedures like VATS or mediastinoscopy.
