59-year-old male with memory loss. History of HIV. Bilateral scattered T2/FLAIR hyperintense foci within the subcortical and periventricular white matter without restricted diffusion.There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild encephalomalacia within the right posterior frontal lobe likely related to prior infarct. Overall the volume of the brain is relatively well-preserved. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.The pituitary gland measures 13 mm in height which is above normal limits and demonstrates heterogeneous enhancement.
1. No specific findings to account for the patient's memory loss.2. Mild encephalomalacia in the right frontal lobe likely related to prior infarct. Relatively mild chronic small vessel ischemic disease is present elsewhere.3. Incidental note is made of a mildly enlarged heterogeneous pituitary gland. Further evaluation with a dedicated MRI pituitary study is suggested.
