Abstract
Objectives To describe the MR imaging features and patterns of local extension of hemangiomas of the eyelid in correlation with the clinical presentation. Patients and methods Retrospective study including 21 MRI (GE, 1.5T, T1 ± Gadolinium, T2 ± fat saturation, 3 planes) examinations performed for eyelid hemangiomas with occlusion > 50% and/or ocular deviation. All examinations were reviewed by two observers using a standardized list of criteria. Results All hemangiomas had a heterogeneous signal described as “salt and pepper” on T2W sequences. The extension was extra-orbital in 8 cases, intra-orbital in 13 cases, extra-conal in 9 cases, intra-conal in 4 cases. The “fat sat T2” sequence provided the best anatomical details. There was a strong correlation between ocular deviation at clinical examination and intra-orbital extension, but no correlation between the extent of eyelid involvement and orbital location of the hemangioma. Dysplastic cerebellum anomalies related to the PHACES syndrome were present in 3 patients. Conclusion MRI of the brain and orbits provides information that appears essential for optimal management of infants with hemangioma of the eyelid.
