Male, 52 years old, with hyponatremia. Assess for causes of SIADH, pituitary lesion. A few scattered T2 hyperintense lesions are seen within the periventricular white matter without mass effect or edema. No restricted diffusion is seen. The cerebral sulci and the cerebellar fissures are prominent compatible with parenchymal volume loss.No evidence of intracranial hemorrhage or any abnormal extra axial fluid collection is seen. The ventricles are slightly prominent related to volume loss but are otherwise unremarkable. Postcontrast images are degraded by motion, but within this limitation, no pathologic parenchymal or extra-axial enhancement is observed.Although this is not a dedicated pituitary examination, no gross or large pituitary lesions are suspected. Please note, however, that this examination is not adequate for the detection of small pituitary lesions.
1.Scattered nonspecific small white matter lesions are seen.2.Volume loss of the brain and cerebellum is seen, greater than expected for age.3.No acute intracranial abnormalities are noted.4.No gross or large pituitary lesions are seen, though please note that this nondedicated examination is not adequate for the assessment of small pituitary lesions.
