Esophageal ultrasound with ultrasound bronchoscope (EUS-B) guided left adrenal biopsy: Case report with review of literature()

A 45-year old man, chronic smoker with a pancoast tumor due to squamous cell carcinoma has been described. The initial diagnosis of lung carcinoma was based on a scant tissue so the exact cell typing was not possible. The initial treatment consisted of platinum based chemotherapy and radiotherapy. He developed a left adrenal lesion on treatment. There was a possibility of metachronous primary. Also, a large tissue sample was required for tumor markers. The lung mass was difficult to access and was static on treatment. A left adrenal biopsy was considered to be more appropriate. A novel approach for left adrenal lesion with esophageal ultrasound using ultrasound bronchoscope (EUS-B) was successfully performed. This article is aimed at describing the use of EUS-B for transdiaphragmatic structures.
