55-year-old female. Evaluate for metastatic brain lesions, hydrocephalus and posterior fossa. Signs and symptoms: Recurrent falls Findings of the extensive white matter low attenuation is noted. These findings are nonspecific however was noted on prior CT examination from 6 -- 6 and 2009 and MRI examination from 5 -- 15 -- 2009. Findings may represent residual edema from patient's multiple previously noted (not present on the current exam) enhancing metastatic lesions). Post infusion images demonstrate no evidence of any abnormal enhancement of the brain parenchyma or the leptomeninges. No metastatic lesions to the brain, leptomeninges or the calvarium is detected. Cortical sulci and ventricular system are within normal size. Follow-up exam with an MRI is highly recommended to exclude other etiologies for a white matter abnormalities.90 CC of Omnipaque 350 was utilized for this a study.
1.No evidence of metastatic lesion to the brain, leptomeninges or calvarium.2.Extensive periventricular and subcortical low attenuation without enhancement as detailed above.
