Clinical question: History of breast cancer in right breast. Signs and symptoms: Evaluate for progression of disease. Nonenhanced head CT:Examination demonstrates diffuse subtle subcortical and periventricular foci of low attenuation which are nonspecific although concern patient's age are highly suspected for minimal small vessel ischemic disease of indeterminate age.There is no evidence of intracranial hemorrhage, edema, mass effect, midline shift or hydrocephalus. This non-infused examination demonstrate no evidence of any findings to suggest metastatic lesions however lack of intravenous contrast significantly reduces the sensitivity of the exam for detection of small metastatic disease to the brain or leptomeninges. Falloff in infuse the study or an enhanced MRI should be considered.The cortical sulci, ventricular system and CSF cisterns remain already normal.Visualized mastoid air cells and paranasal sinuses are unremarkable.Images through the orbit demonstrate evidence of prior cataract surgery.Calvarium is intact.
1.Negative non-infused head CT for metastatic disease. Recommend further studies will an enhanced CT or an enhanced MRI is recommended.2.Small vessel disease of indeterminate age.3.Negative calvarium, paranasal sinuses and mastoid air cells.
