Breast cancer, with additional lung cancer patient. Metastasis workup. Due to significant motion artifacts, image quality has been degraded.There is focal mildly restricted diffusion area on the left middle temporal gyrus posterior aspect. The lesion shows subtle high signal intensity on FLAIR images but no susceptibility artifacts on gradient echo images, thought there were significant motion artifacts. Thus, this lesion is likely represent a subacute subcortical ischemic lesion.There is no large intracranial mass.Scattered high signal intensities on FLAIR images are non specific.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Possible subacute ischemic lesion on the left middle temporal gyrus posterior aspect.2. Non specific small vessel ischemic disease.3. No evidence of intra cranial mass or abnormal edema.Comment: if clinically indicated, brain MRI with and without contrast enhancement is recommended for metastasis work up.
