Male, 69 years old, with progressive altered mental status, assess for metastatic disease. No evidence of edema, mass effect or pathologic enhancement is seen to suggest intracranial metastatic disease.Moderate confluent T2 hyperintensity is seen along the lateral ventricular margins bilaterally with a few additional scattered patchy foci including in the brain stem. These findings are nonspecific.No evidence of restricted diffusion is seen. No findings to suggest intracranial hemorrhage or any abnormal extra-axial fluid are detected. The ventricles are slightly prominent but not out of proportion to the degree of sulcal widening.
1. No evidence of intracranial metastatic disease.2. No definite acute intracranial abnormalities.3. White matter signal abnormality primarily in the periventricular regions is a nonspecific finding which may represent the sequelae of chronic microvascular ischemia or an effect of therapy among other etiologies.
