Visual field defect, unspecified [368.40], Reason for Study: ^Reason: Bitemporal hemianopia History: Bitemporal hemianopia Orbit MRIThe globes, optic nerves, extraocular muscles and retroglobal spaces are symmetric and normal. The lacrimal glands are normal. There is no evidence of signal abnormality, mass, or abnormal contrast enhancement. Optic chiasm appears to be normal.Brain MRI No evidence of acute ischemic or hemorrhagic lesion on the scan.Scattered high signal intensities on FLAIR imaging on periventricular white matter indicate nonspecific small vessel ischemic disease.There is a well-circumscribed about 7 mm sized pineal gland cyst without evidence of mass effect toward surrounding structures.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra- or extra-axial fluid collection, hemorrhage, restricted diffusion/acute ischemia or abnormal contrast enhancement. 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. Mucosal thickening on bilateral maxillary sinuses, frontal sinus and ethmoid sinuses and there is small retention cyst on the right maxillary sinus.
1. Normal orbit MRI scan.2. No evidence of acute ischemic or hemorrhagic lesion on the scan. No abnormal enhancement.3. Minimal nonspecific small vessel ischemic disease.
