Asymptomatic orbital cavernous hemangiomas.
Computed tomographic (CT) scanning and magnetic resonance imaging (MRI) are commonly performed to evaluate neurologic symptoms. Rarely are asymptomatic orbital tumors discovered, creating uncertainty about their management. Eleven patients are presented who were referred for asymptomatic orbital tumors discovered on either CT scanning or MRI performed for unrelated symptoms of headache, vertigo, peripheral numbness, seizures, stroke, or hallucinations. The asymptomatic orbital tumors were diagnosed clinically and radiologically as cavernous hemangiomas. All the patients were followed clinically and neuroradiologically for an average of 37 months (range, 8 to 120 months). None of the tumors enlarged during this time. The authors conclude that patients who have asymptomatic cavernous hemangiomas, discovered by coincidence during neuroimaging, that bear no relation to the indication for obtaining the CT scan or MRI, can be safely followed by observation as an alternative to surgical excision.
