Unspecified convulsions [R56.9], Reason for Study: ^Reason: r/o stroke vs mas lesion History: 1st onset seizure Motion artifacts degraded exam quality.No evidence of acute ischemic or hemorrhagic lesion on the scan.On FLAIR images especially coronal scan, there are relatively diffuse high signal intensities on bilateral hippocampi (left side more prominent than right). However, on axial FLAIR images those increased signal intensities were not as conspicuous as those of coronal FLAIR images. In addition, there is no evidence of hippocampal volume loss or deformity. Thus, this finding may suggest possible post ictal status or artifacts. 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, 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 bilateral mastoid air cells show opacifications. Mucosal thickening on the left maxillary sinus.
1. Diffuse bilateral hippocampal high signal intensity on FLAIR coronal images which may indicate acute post ictal status or artifact. Follow up scan can be considered for further imaging evaluation.2. No evidence of acute ischemic or hemorrhagic lesion. No mass lesion identified.
