A 72-year-old man presented with weight loss, night sweats and haemoptysis and was hypotensive. CT imaging showed rapidly enlarging bilateral adrenal masses, and he was found to have primary adrenal insufficiency. An adrenal gland biopsy revealed the rare diagnosis of primary adrenal lymphoma. This unique case highlights possible rare causes of adrenal masses and adrenal insufficiency, their investigation and management principles.
