Imaging Procedures and Findings

An intraconal lesion with low signal intensity at T1 and intermediate signal intensity at T2 is noted. Proptosis of left eye and a left maxillary sinus retention cyst are also evident. Optic nerve is intact.

Discussion

Hemangiomas can be classified into two distinct entities: cavernous and capillary. They are seen in different age groups: cavernous hemangiomas are seen in young adults, most commonly between the second and fourth decades of life, whereas capillary hemangiomas are seen in young pediatric patients. Cavernous hemangiomas are the most common adult orbital mass lesion . They are actually venous malformations rather than true neoplasms. They tend to be well encapsulated with distinct margins and are usually intraconal. On CT imaging, they are often hyperdense. Phleboliths may be present. On MR images, signal on Tl-weighted images are variable, but hyperintensity may be associated with thrombosis. Cavernous hemangiomas are usually hyperintense on T2-weighted images. Intense enhancement is usually seen with both CT and MRI. Capillary hemangiomas often are found in infants during the first year of life. They tend to regress with age. Prominent arterial supply from the external or internal carotid arterial systems usually is seen. On CT and MR!, they present as an intensely enhancing lobulated mass, with low intensity to isointensity on Tl-weighted images and hyperintensity on T2-weighted images.

Final Diagnosis

Hemangioma of orbit
