(A) Facial paranasal sinus computed tomography reveals a homogeneous high-density cyst-like lesion over the left lacrimal sac (arrow). Marked periosteal mucosal thickening of the nasal cavity with polypoid lesions is also noted. (B) Head orbits postgadolinium T1-weighted magnetic resonance imaging (MRI) reveals an iso- to hyperintense homogeneous lesion (17 mm × 12 mm × 20 mm) with contrast enhancement over left lacrimal sac. Paranasal sinusitis is also noted. (C) T2-weighted MRI reveals slightly hyperintense signal of the lesion.
