Vascular malformations may occur during the development of the arterial, venous, and lymphatic systems in isolation or in combination. Orbital venolymphatic malformations (OVLM) are particularly challenging to treat because they infiltrate and remodel normal structures within the tight orbital space and lead to substantial ocular discomfort, visual disability, and facial disfigurement. Herein, we report two cases of OVLMs with different presenting clinical features and treatment options. We compare the image qualities among computed tomography and 1.5T and 3T magnetic resonance imaging and discuss how better anatomical resolution in the latter aid in the management of OVLM.
