Syncope and collapse [R55], Reason for Study: ^Reason: eval brain History: new onset seizure No evidence of acute ischemic or hemorrhagic lesion.There are, however, 3 focal low signal intensity lesions on anterior aspect of upper medulla and left cerebellar hemisphere on T2 image (series 601, image 24). Those lesions are not seen on coronal T2 image, nor on FLAIR images and not showing susceptibility artifacts on Gradient echo image. Therefore, they are most likely to be artifacts.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, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear. Left maxillary sinus retention cyst.
