Malignant neoplasm of bronchus and lung, unspecified site [162.9], Reason for Study: ^Reason: rule out metastases History: ams, There is no evidence of acute ischemic or hemorrhagic lesion on this scan.There is a focal high signal intensity on the right post central gyrus (224, series 406) but it does not show restricted diffusion and shows high signal intensity on T2 and FLAIR indicate T2 shine through artifact. Several scattered high signal intensity foci on bilateral hemispheres on FLAIR images indicate non specific.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. 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.
No evidence of acute ischemic or hemorrhagic lesion on the scan.Non specific white matter lesions on FLAIR images as described above.If metastatic lesion is suspicious, MR exam should be repeated with Gadolinium enhancement.
