Intramuscular hemangioma (IMH) is rare in the ocular adnexa and is uncommonly found in infants. We describe a 1-month-old female infant with an unremarkable birth history presented with subacute onset of right upper eyelid swelling. Clinical examination revealed a purplish subcutaneous mass over the right upper eyelid causing mechanical ptosis. MRI revealed a well-defined subcutaneous mass, which was hyperintense on the T1 weighted images and showed intense enhancement after administration of intravenous gadolinium. Our working diagnosis was infantile capillary hemangioma, and the patient received two intralesional steroid injections without diminishing the lesion size. The lesion had become static in size and the subsequent MRI 14 years later revealed the same lesion had become hyperintense on the T1 weighted image. An excisional biopsy revealed mixed type IMH. IMH should be considered among young patients with upper eyelid swelling, particularly in those who show a poor response to steroid treatment.
