Linear probe 19-gauge endobronchial ultrasound diagnosis of a benign chondroid hamartoma

We report a case of a 68-year-old gentleman, found to have a right hilar soft tissue mass whilst undergoing CT staging for prostate cancer. MRI imaging showed a heterogenous, enhancing solid mass without evidence of fat content. A linear probe endobronchial ultrasound-guided transbronchial needle aspiration was performed using a 19G needle. This confirmed the diagnosis of a benign chondroid hamartoma, avoiding the need for more invasive surgical biopsy.

High Diagnostic Yield

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive modality for mediastinal lymph node staging in lung cancer patients as well as for the diagnosis of mediastinal and hilar adenopathy. The high diagnostic yield of EBUS-TBNA for lymph node staging has been shown in systematic reviews and meta-analysis. It has attracted physicians and surgeons as an alternative modality to surgical biopsy for the assessment of patients with enlarged mediastinal and/or hilar lymph nodes. Cell blocks obtained by EBUS-TBNA can be applicable not only for pathologic diagnosis but also for further investigations such as immunohistochemistry and fluorescence in situ hybridization. In addition, samples obtained by EBUS-TBNA can also be used for molecular analysis. Unlike regular bronchoscopy, EBUS-TBNA uses the convex probe EBUS with an ultrasound probe on the tip of a flexible bronchoscope. It is important for the bronchoscopist to fully understand the mediastinal anatomy and be able to correlate it with the ultrasound images for a successful EBUS-TBNA. The dedicated transbronchial needle used for EBUS-TBNA is somewhat different from an ordinary transbronchial biopsy forceps. Training is mandatory for achieving high diagnostic yield without complications. The learning curve of EBUS-TBNA is different from each physician, and continuous training program will be needed for impartiality. This article explains the detailed techniques of EBUS-TBNA to master this innovative procedure.

Acute Pericarditis

A 27-year-old man was diagnosed with inflammatory myofibroblastic tumor, and multiple lymph node and subcutaneous metastases. After several administrations of anti-tumor therapy, he underwent mediastinal lymph node biopsy using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to confirm tumor relapse. Five weeks later, he complained of chest pain, then rapidly developed shock due to acute pericarditis. Although he was treated with antibiotics for anaerobic bacterial infection and cardiac drainage, mediastinal lymph node abscess and pericarditis did not improve. After the surgical procedure, his physical condition dramatically improved and he was treated with another molecularly targeted therapy. Pericarditis associated with EBUS-TBNA is extremely rare. In this case, salvage was achieved by surgical drainage of the lymph node abscess and pericarditis, and long survival was obtained with further administration of anti-tumor treatment.
