Questioning abnormal findings on CT-scan: new daily persistent headache. There is a punctate focus of susceptibility effect in the right frontal lobe anterior periventricular white matter. There are also a few scattered punctate foci of high T2 signal predominantly in the white matter of the bilateral frontal lobes. There is no evidence of acute infarct. 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.
A punctate focus of susceptibility effect in the right frontal lobe anterior periventricular white matter corresponds to the nonspecific calcification demonstrated on the prior CT and may represent a cavernous malformation, for example. A few scattered punctate foci of high T2 signal predominantly in the white matter of the bilateral frontal lobes are also nonspecific.
