Background. Few studies have investigated whether endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) can be conducted without a balloon for a definitive diagnosis of mediastinal lymphadenopathy. Case 1. A woman in her 70s with an allergy to rubber gloves. During an examination for uveitis, CT showed multiple enlarged lymph nodes in #4R and #7. Case 2. A man in his 40s presented with an allergy to rubber gloves. Follow-up CT after the surgical treatment of lung adenocarcinoma revealed an enlarged lymph node (#7). Results. EBUS-TBNA was performed in these two cases to definitively diagnose enlarged mediastinal lymph nodes without a balloon. In Case 1, #7 and #4R had short diameters of 10 mm and 15 mm, respectively, while in Case 2, #7 had a short diameter of 17 mm. The lesion was delineated and punctured without a balloon. Case 1 was diagnosed with sarcoidosis, and case 2 was diagnosed with recurrent lung adenocarcinoma. Conclusions. It is crucial to carefully assess whether the target lesion is puncturable before the examination when performing EBUS-TBNA without a balloon.
