New onset double vision, rule out intracranial mass History: new onset double vision. The left maxillary sinus is relatively small and there is a low-lying left orbital floor. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull and scalp soft tissues are grossly unremarkable.
1. The left maxillary sinus is relatively small and there is a low-lying left orbital floor, which may be developmental or post-traumatic in nature. Dedicated maxillofacial imaging may be useful for further evaluation.2. No evidence of intracranial hemorrhage, mass, or acute infarct.
