Giant frontal mucocele presenting with displacement of the eye globe

Abstract

In this case, a 70-year-old female patient presented with large forehead swelling that occurred 2 years prior, with slow progressive enlargement that mimicked the behavior of a neoplasm. There was severe inferior displacement of the right orbital globe to the level of the nares. Brain computed tomography showed a large expansive lesion in the right frontal sinus with bony wall thinning without destruction or erosion. Brain magnetic resonance imaging showed high signal intensity of the contents in T1- and T2-weighted images with only peripheral enhancement after contrast administration. These features were consistent with a typical right frontal mucocele. Keywords: Giant, Frontal, Mucocele, CT, MRI, Displacement
