There is a left orbital intraconal rim-enhancing fluid collection measuring up to 1.0 cm that abuts the left optic nerve with surrounding stranding/inflammatory changes. There is asymmetric edema and enhancement involving the left lateral and inferior rectus muscles, There is redemonstration of a 4.0 cm rim-enhancing collection along the floor of the anterior cranial fossa, extending to the left middle cranial fossa rim-enhancing collection with associated regional dual thickening. There is asymmetric fullness and enhancement of the left cavernous sinus, The collection abuts the left orbital apex/canalicular and prechiasmatic segments of the left optic nerve, There is prominent adjacent edema in the left greater than right frontal lobes with regional mass effect. There is up to 8 mm rightward midline shift at the level of the anterior inter-hemispheric fissure. There is suggestion of trace inflammatory changes and enhancement in the left retrobulbar fat, Otherwise, the right ocular globe, optic nerve, and extra-ocular muscles appear normal, Post-surgical changes are seen related to left submandibular and masticator space abscess drainage with regional Penrose drain and surrounding edema/enlargement of the muscles of mastication. There is asymmetric subtle edema and enhancement along the left parotid gland.
