Transient Focal Magnetic Resonance Imaging Abnormalities After Status Epilepticus Showed 11C-Methionine Uptake with Positron Emission Tomography in a Patient with Cerebral Cavernous Malformation

This case suggests that transient focal MRI abnormalities after SE may indicate reversible cortical brain edema. Accumulation of 11C-methionine on PET could occur in the corresponding lesion even if no malignant tumor is present. Because distinguishing transient MRI abnormalities after SE from a glioma is difficult, repeated imaging studies should be performed in patients with brain tumor-related seizures.
