MRI
MRI of the face demonstrated a well-circumscribed expansile mass centered around the left nasal passage with heterogenous serpiginous internal enhancement. The mass was hypointense on T1-weighted images (T1WI) and hyperintense on T2-weighted images (T2WI) with linear internal hypodensities that demonstrated loss of signal on fat-saturated images. It did not restrict diffusion. Contrast enhanced images demonstrated a heterogeneously enhancing mass with internal separations and areas of low signal intensity. It exerted mass effect on the surrounding structures with mild deviation on the left medial rectus muscle and rightward deviation of the nasal septum
