Right intranasal mass asses for intracranial invasion: right nasal congestion. There is a lobulated and heterogeneous mass within the right nasal cavity that measures up to 55 mm in length. There is mucosal thickening and fluid in the right maxillary and ethmoid sinuses, as well as mucosal thickening in the right frontal sinus, a left maxillary sinus retention cyst, and fluid in the bilateral sphenoid sinuses. There is deviation of the nasal septum to the left. There are secretions in the nasopharynx. There are bilateral lens implants. There is a chronic lacunar infarct in the right basal ganglia and scattered foci of nonspecific cerebral white matter T2 hyperintensity.
1. Preoperative planning MRI demonstrates a mass centered in the right nasal cavity with superimposed obstructed sinonasal inflammatory disease, likely both acute and chronic.2. Chronic lacunar infarct in the right basal ganglia.
