The main indications of endobronchial ultrasound (EBUS) include staging of lung cancer patients and diagnosis of enlarged mediastinal lymph nodes or lesions. It can usually be done as a day care procedure under conscious anesthesia. This modality has largely replaced the use of gold standard surgical mediastinoscopy for diagnosis because of its high efficacy, safety, low cost, and wider availability. As Guarize et al.[1] showed, EBUS had a sensitivity and specificity of 91.7% and 93.6%, respectively, and there were no major complications related to the procedure. With the increasing expertise in and availability of EBUS, clinicians are now exploring its use for sampling substernal goiter lesions, posteriorly located pericardial effusion, paraspinal lesions as well as difficult to access lesions.[2] Sinha et al.[3] had reported EBUS-guided paraspinal sampling (from the tracheobronchial tree) after failing to obtain tissue via computed tomography (CT)-guided approach and bone marrow aspirate and biopsy from the spine. We report a similar case which was approached by endoscopic ultrasound fine-needle aspiration with an echobronchoscope (EUS-B-FNA).

Our patient is a 21-year-old male who had been diagnosed as a case of chronic granulomatous disease (CGD) at the age of 17 years, when he developed lower respiratory tract disease, pyomyositis, and multiple abscesses over his back. He had responded to treatment with intravenous antibiotics, and subsequently, reactive oxygen species stimulation index was found to be low suggestive of CGD.

Now, he presented with complaints of mid-back ache and significant loss of weight and appetite for the last 6 months. However, there was no fever. On examination, he had a few subcentimetric cervical lymph nodes. The rest of the systemic examination was within normal limits.

His routine blood investigations were normal. Chest X-ray showed T7 vertebral body collapse. Contrast-enhanced CT chest revealed a prevertebral heterogeneously enhancing lesion, suggestive of partially organized collection extending from T5 to T9 vertebrae [Figure 1]. The radiological picture was suggestive of a chronic infective process like tuberculosis. For determining the exact etiology, sampling and microbiological investigati ons were planned. The position of the lesion made it difficult for a transthoracic approach. As the lesion abutted the tracheobronchial tree and the esophagus around the carina, a decision was made to approach with the help of EBUS. However, the lesion could only be partially visualized at the carina, and on rapid on-site evaluation (ROSE), the sample was deemed unsatisfactory. Hence, endoscopic ultrasound with echobronchoscope (EUS-B) approach was used, and after identifying the usual landmarks of liver and heart, the scope was positioned to clearly visualize the lesion [Figure 2] and aspirate was taken. Two passes were taken and ROSE showed lymphoid tissue with necrotic background [Figure 3]. Cartridge-based nucleic acid amplification test from aspirate showed Mycobacterium tuberculosis sensitive to rifampicin and cytology showed abundant necrosis and stained positive for acid-fast bacilli [Figure 4].

Based on the above reports, the patient was diagnosed as a case of tuberculosis of the spine. He was started on antitubercular therapy with isoniazid, rifampicin, pyrazinamide, and ethambutol. The patient now has improved weight and appetite, and back pain has resolved.

In our case, the paraspinal collection could not be visualized properly with EBUS approach, so next EUS-B was done and the lesion could be successfully visualized and sampled. Dhooria et al.[4] and Oki et al.[5] had showed efficacy and safety of EUS-B where EBUS approach failed or was contraindicated. This case highlights the utility of the EUS-B approach in sampling mediastinal lesions not accessible by transthoracic or transbronchial route.
