Multiple cavernous hemangiomas in the orbit: A case report and review of the literature

RATIONAL: Cavernous hemangiomas are one of the most common benign primary orbital lesions. These tumors are insidious in onset, slowly progressive and present more often in middle aged women. Multiple orbital cavernous hemangiomas are extremely rare, and only a few cases have been reported in the published literature. PATIENT CONCERNS: Here, we report the diagnosis and treatment of multiple cavernous hemangiomas in the right orbit of a female patient with impaired visual acuity and proptosis of the eye for more than 10 years. DIAGNOSIS: Magnetic resonance imaging of the orbit showed a giant and irregular soft mass filling the intraconal and extraconal space of the right orbit, compressing the right optic nerve. After tumor resection, histopathological examination confirmed the diagnosis of cavernous hemangioma. INTERVENTIONS: A lateral orbitotomy was performed and a total of 13 tumors were excised, with the largest tumor measuring approximately 2.5 × 3.0 cm. OUTCOMES: The visual acuity of the patient was preserved, with only a slightly dilated pupil of the right eye. The follow-up period was 6 months with no signs of recurrence. LESSONS: Multiple cavernous hemangiomas in the orbit is rare and should be excised surgically as soon as possible.
