Male, 67 years old, with history of surgery on the optic nerve in 1986, presenting with visual field alteration. Periventricular T2 hyperintensity, particularly at the level of the atria, is stable to at most minimally progressed when compared to the prior examination. Encephalomalacia of the left gyrus rectus is unchanged. T2 signal abnormality seen on the prior examination within the left anterior temporal lobe has resolved.No evidence of restricted diffusion, mass effect or significant parenchymal edema is seen. No acute intracranial hemorrhage or any new abnormal extra-axial fluid collection is observed. Postcontrast images show no pathologic parenchymal or extra-axial enhancement.Please note this examination was not tailored for the assessment of the orbits. Within this limitation, enophthalmos of the left globe is a stable finding. The left optic nerve is not visualized, nor is the left superior rectus, findings which also appear unchanged from prior.
1.Periventricular T2 hyperintensity is stable to minimally progressed. This is a nonspecific finding which may reflect chronic microvascular ischemic disease.2.Stable encephalomalacia of the left gyrus rectus. Signal abnormality seen on the prior examination within the left anterior temporal lobe has resolved.3.No new areas of parenchymal signal abnormality or pathologic enhancement are seen.4.Although not protocoled as a dedicated orbital examination, enophthalmos of the left globe, along with inability to visualize the left optic nerve and left superior rectus muscle, are stable findings.
