Clinical question: Please evaluate for old infarct or other cause for long-term change in memory. Signs and symptoms: Memory change. Enhanced CT of brain:Examination demonstrate a partially calcific and likely enhancing (no pre-infusion study available) left frontal lobe tumor which extends superiorly and involves the left basal ganglial/caudate nucleus. There is no evidence of edema, hemorrhage or mass-effect with this finding. There is ex vacuo dilatation of left frontal horn. This may be the result of a prior stroke. On coronal reformatted images this mass measures 23-mm in cranial cephalad access and 18.7-mm in transverse axis. On axial image 10 the tumor measures 16mm in AP access and 16-mm in transverse axis. This lesion may represent a cavernoma. Follow-up exam in an MRI is recommended. CT examination of brain is otherwise unremarkable.
