What is the most common benign orbital tumor in adults?

Explanation:
The most common benign orbital tumor in adults is a cavernous hemangioma. This lesion is a slow-growing vascular tumor that typically sits in the intraconal space and presents as unilateral, progressive, painless proptosis in middle-aged adults. Capillary hemangiomas are predominantly infantile and not common in adults. Lymphangiomas are congenital malformations that usually appear in childhood and may enlarge with hemorrhage, making them far less common in adults. Meningiomas, while a recognized adult orbital tumor (often optic nerve sheath meningiomas), are not as common as cavernous hemangiomas when ranking benign orbital tumors in adults.
