Abstract:
Adrenal incidentalomas are typically monitored for tumor growth during follow-up visits. We report the case of a 70-year-old man with a non-functioning left adrenal mass that exhibited transient regression and was ultimately diagnosed as diffuse large B-cell lymphoma. The diagnosis was suspected based on elevated serum lactate dehydrogenase levels and left testicular enlargement, prompting an evaluation using fluorodeoxyglucose positron emission tomography/computed tomography and confirmation by radical orchiectomy. This case highlights the importance of considering malignant lymphoma when adrenal masses regress transiently and underscores the risk of adrenal insufficiency even after the completion of lymphoma treatment.
