Metastasis to adrenal glands from primary pulmonary carcinoma is quite a common occurrence. In most cases, the diagnosis is made based on an imaging evaluation done because of chronic non-specific pulmonary symptoms. Further evaluation to determine the type of carcinoma is done using histopathological evaluation of the primary lung lesion. Here, we have described a case of a 60-year-old man who presented with chest pain and was incidentally detected with a lower lung mass and a bulky left adrenal gland in the upper abdominal cuts on a CT of the thorax. As the evaluation of the fine needle aspiration (FNA) sample from lung lesion couldn't be successfully performed, sampling from the left adrenal gland was attempted under the guidance of conventional endoscopic ultrasound using an endobronchial ultrasound probe (EUS-B). When the technique failed to localise the left adrenal gland, a modification was made and the gland was localised using the spleen as a marker. This case further presented a challenge, when due to the unfolding of rugae, the FNA needle wasn't able to reach up to the left adrenal gland. Further adjustment was made and the maximum depth of the gland from the margin was measured and the needle was fully freed. Multiple jabs were made and sampling was successfully done. Cellblock confirmed the presence of adenocarcinoma of pulmonary origin, positive for thyroid transcription factor 1 (TTF-1). The patient remained stable and did not present with any early or late post-procedural complications. The patient was started on appropriate chemotherapy for the disease. He has received three cycles of carboplatin and pemetrexed till now and is doing well.
