Left frontoorbital tumor with skull base extension POD#1 s/p left craniotomy, left orbitotomy with reconstruction and orbitization of left frontal sinus and reconstruction of orbital rim with particular bone graft and pericranial flap and with resuspension of left temporalis muscle . There are recent postoperative findings related to left craniotomy and orbitotomy with reconstruction and obliteration of the left frontal sinus and reconstruction of orbital rim with diffuse overlying scalp and periorbital swelling. There is graft material and a subperiosteal postoperative fluid collection in the superior left orbit that measures up to 8 mm in thickness with mild flattening of the orbital contents. There is unchanged mild asymmetric thickening of the roof of the left orbital apex. There is mild protrusion of the intracranial contents into the obliterated left frontal sinus. There is persistent bowing of the lateral wall of the left orbit associated with a middle cranial fossa arachnoid cyst that measures up to 18 mm in width. There is mild left proptosis. There is no evidence of intraorbital mass lesions. The bilateral optic nerves appear to be intact. There is mild left cerebral convexity dural postoperative enhancement. There is mild edema in the left orbitofrontal gyri. The ventricles are unchanged in size and configuration, with a left choroid fissure cyst. There is no midline shift or herniation. There is moderate right maxillary sinus mucosal thickening and a left sphenoid sinus retention cyst. There is minimal fluid signal in the right mastoid air cells.
1. Recent postoperative findings related to left superior orbital wall reconstruction and left frontal sinus decompression with unchanged mild asymmetric thickening of the roof of the left orbital apex and a superior left orbit subperiosteal postoperative fluid collection that measures up to 8 mm in thickness, but no evidence of intraorbital mass lesions otherwise.2. Persistent bowing of the lateral wall of the left orbit associated with a middle cranial fossa arachnoid cyst that contributes to proptosis.
