Case Of the Week (COW) 05 Jan 2014
Answer:
Orbital Lymphangioma.
Findings:
Multiseptate, multilobulated lesion T2 hyperintense lesion seen in left orbit with multiple fluid-fluid levels within multiple locules.
Discussion:
Lymphangioma is a vascular tumor of the orbit with a propensity for recurrent hemorrhage. These tumors may be difficult to diagnose in young patients who present with sudden proptosis due to hemorrhage into a previously unrecognized lesion. Magnetic resonance imaging (MRI) should be ideally suited for evaluating lymphangioma due to the unique ability of MRI to characterize hemorrhage because of the paramagnetic qualities of hemoglobin.
