Cavernous hemangioma is a frequent and the most common, primary, benign tumor of the orbit in adults. It is typically single and unilateral, considered not to recur after having been completely excised. Multiple orbital cavernous hemangiomas without signs of hemangiomatosis are rare. Multiple cavernous hemangiomas may recur after a complete excision and may exist with concurrent systemic tumors. Tumor recurrence is supposed to develop from vasculature that is present already in response to a proliferate stimulus.
