Case Images
Diagnosis
Hemangioma
Findings
MR – Sagittal and axial T1, axial fat suppressed T2 and axial post-gadolinium fat suppressed T1 images demonstrate an enhancing microlobuted which is isointense onT1 and hyperintense on T2.
Discussion
Hemangiomas are the most common tumor of infancy. It is estimated that they occur in 1%–2% of the population in general and in up to 10% of Caucasians. Periorbital hemangiomas are often imaged to assess the extent of retro-orbital involvement and the potential for compromise of orbital movement and vision. Typically, proliferating hemangiomas are isointense relative to muscle on T1-weighted images, have high signal intensity on T2-weighted images, demonstrate homogeneous enhancement, and have internal flow voids. The flow voids are highly suggestive but not a specific feature of hemangiomas.
