[Bilateral adrenal hemorrhage due to adrenal metastasis of lung cancer].

A 58-year-old man presented with nausea and left flank pain. The patient was referred to our hospital based on clear detection of anemia and computed tomography findings of bilateral adrenal tumors with hemorrhage and a mass in the apex of the left lung. Right adrenal artery embolization had no effect on enlargement of the right adrenal hematoma or advanced anemia. Right adrenalectomy was then performed in an attempt to control hemorrhaging and make a definitive diagnosis, and the patient's anemia improved following the operation. Histopathological diagnosis suggested adrenal metastasis of lung adenocarcinoma, which was subsequently diagnosed given similarities in transbronchial biopsy findings to those in the right adrenal gland. Adrenal hemorrhage due to metastasis of lung cancer is an extremely rare condition; indeed, to our knowledge, the present case is only the 26th reported worldwide. However, prognosis for this mortal condition may be improved should patients receive adrenalectomy followed by an appropriate treatment regimen.
