Clinical question: History of right parietal hemorrhagic stroke. Signs and symptoms: Left-sided weakness. Nonenhanced head CT:Subacute old right parietal and posterior stroke is again identified. There is only subtle mass effect of the adjacent cortical sulci in portions of the stroke. No evidence of hemorrhage. The cortical sulci, ventricular system and CSF cisterns are otherwise unremarkable. There is a small focus of increased density measuring 5.8 times 4-mm in size in the AP lateral to the right head of caudate nucleus. Review of prior limited MRI examination (only diffusion weighted images were obtained) reveals no abnormality. This finding may represent a small nonspecific calcification. Possibility of small hemorrhage cannot be ruled out however this is not associated with any edema of adjacent brain parenchyma.
