History of breast cancer, on chemotherapy, now with right-sided headache and blurry vision. Evaluate for metastases. There is no evidence of intracranial hemorrhage, edema or midline shift. Though no mass effect is present, evaluation for metastatic lesions is limited by a lack of intravenous contrast. If there is a high suspicion for metastases, an MRI with contrast is recommended.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. There is opacification of a few ethmoid air cells. The remaining visualized paranasal sinuses and mastoid air cells are normally pneumatized.
No acute intracranial abnormality. No mass lesions are identified. If there is strong clinical concern for intracranial metastases, an MRI with contrast may be considered for further evaluation.
