Localized swelling, mass and lump, head [R22.0] / Cellulitis of face [L03.211], Reason for Study: ^Reason: eval infection History: abscess Re-demonstration of right paraorbital sinus inflammation with subperiosteal abscess formation along the lamina papyracea with proptosis. There is 8.8mm x 33mm sized extra axial fluid collection with internal air at the right anterior cranial fossa just above the cribriform plate with peripheral enhancement indicating extension of ethmoid sinus lesion extension. Right frontal and temporal area dura and the left frontal dural enhancement indicating local inflammatory reaction.Subtle high signal intensity on FLAIR/T2 at the right mesial orbital gyrus indicating possible reactive inflammatory changes of the brain parenchyme. There is no evidence of acute ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.
1. Right paraorbital-paranasal abscess with intracranial extension results right side anterior cranial fossa extra-axial fluid collection as described above associated with reactive changes of right mesial orbital gyrus and overlying dura.2. No evidence of brain parenchymal abscess, no acute ischemic or hemorrhagic lesion.
