Abstract

Background: We reported the application of endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (FNA) in the local staging of lung cancer. Up to 16% of patients with lung cancer may have adrenal masses. The role of EUS in the characterization of the adrenal gland, as well as EUS-guided FNA of the adrenal gland, has not been described. Methods: The adrenal gland was characterized by EUS in 30 of 31 (97%) patients. EUS-guided FNA of an adrenal was performed in one patient. Anatomic correlation and ex vivo images were obtained. Results: The average dimension was 2.5 cm (range 1.4 to 3.5) × 0.8 cm (range 0.3 to 1.4) with two morphologic types: “seagull” and “elliptical.” One patient with lung cancer and a left adrenal mass with a nondiagnostic CT-guided FNA underwent EUS-guided FNA, which established the diagnosis of metastatic adenocarcinoma. Surgery was avoided. Conclusions: The left adrenal can be imaged by EUS in almost all patients. EUS-guided FNA may be useful when applied to left adrenal metastatic tumors for tissue diagnosis.

METHODS

EUS was performed in 31 consecutive patients for various indications (diagnosis and staging of gastrointestinal and lung malignancies). Of the patients in whom a final diagnosis was known by surgery or 6-month follow-up, 9 of 23 had benign lesions and 14 of 23 had malignant lesions. The left adrenal was specifically searched for in all patients. There were 11 male and 20 female patients with ages ranging from 38 to 92 years. EUS was done using the Olympus GF-UM20 echoendoscope (Olympus America

RESULTS

The left adrenal gland was detected and characterized in 30 of 31 (97%) patients. In one patient, the adrenal gland was not identified.

The echoendoscope was advanced through the esophagus into the proximal stomach. The abdominal aorta was first identified just below the gastroesophageal junction. The splenic vein was then isolated by advancing the transducer forward with a clockwise rotation. The splenic hilum was found by following the splenic vein laterally (further clockwise rotation and

DISCUSSION

The application of EUS in imaging the adrenal gland has not been described. Previously in our experience, if the adrenal was imaged, it was an incidental finding of no clinical significance. However, now that EUS may play a role in the lymph node staging of lung cancer (and adrenal metastasis occurs not infrequently), imaging the adrenal may have a clinical application.
