They are typically discovered incidentally during imaging for other conditions. We report an unusual case of adrenal cavernous hemangioma identified during adrenalectomy surgery. A 60-year-old woman was diagnosed with a left adrenal mass found on a lung CT scan performed due to dyspnea, attributed to bronchiectasis. The imaging revealed a 40 mm adrenal mass with heterogeneous enhancement and calcification. Although adrenal function tests excluded pheochromocytoma, the manipulation of the adrenal gland during surgery unexpectedly triggered a hypertensive crisis. Postoperatively, the patient required intensive monitoring but stabilized and was discharged without the need for antihypertensive medications. Histopathological examination confirmed the diagnosis of cavernous hemangioma. Adrenal cavernous hemangiomas are rare benign tumors typically diagnosed after adrenalectomy by histological examination. Their distinct radiological features on CT scans can be helpful for diagnosis and may prevent unnecessary overtreatment in some cases. https://www.caspjs.com/article_727592_e90396e29c80acb64d8f632452c35a19.pdf
