We report a 65-year-old man who was diagnosed with focal status epilepticus generating a dreamy state, delusions with anxiety, complex audiovisual hallucinations, elementary auditory hallucinations, and metamorphopsia with a growing large lateral temporal lobe lesion. After administrating anti-seizure drugs, all the symptoms disappeared, and brain magnetic resonance imaging revealed ipsilateral hippocampal sclerosis. To the best of our knowledge, this is the first report to present all the symptoms in one epilepsy case. On the basis of semiology, electroencephalography, and brain magnetic resonance imaging, we speculated that epileptic activities that have originated from the lateral lesion might have propagated to the ipsilateral mesial temporal lobe, causing hippocampal sclerosis.

We report on a 44-year-old woman who was diagnosed with toxic epidermal necrolysis (TEN) during the recovery phase from autoimmune limbic encephalitis with anti-glutamate receptor antibodies. Both, autoimmune limbic encephalitis and TEN are very rare diseases. The co-existence of the two diseases has not yet been reported. We speculate that the total of 18 drugs needed for the treatment of encephalitis might have increased the risk of TEN. Similar reports would be required to elucidate the pathophysiology of the co-existence.

This report describes a rare case presenting with dystonic seizures due to anti-N-methyl-D-aspartate (NMDA) receptor encephalitis. The patient was an 18-year-old woman with repeated right-dominant dystonic seizures even under sedation. Single-photon emission computed tomography (SPECT) showed intense hyperperfusion of the caudate nuclei, putamen, globus pallidus, thalamus, and insula on the left side, suggesting encephalitis. Antibodies against NMDA receptors were detected in the sera and cerebrospinal fluids. Immune-mediated treatments were administered. Three months later, the dystonic seizures disappeared. We diagnosed her with anti-NMDA receptor encephalitis. SPECT suggested that the main region of encephalitis was the basal ganglia. Therefore, we propose that the patient’s dystonic seizures may originate from the insula and be generated by intense hyperactivity of the basal ganglia.
