Abstract
The clinical features of neuropsychiatric systemic lupus erythematosus (NPSLE) are heterogeneous. Furthermore, therapeutic decision-making for NPSLE depends on the recognition of clinical syndromes that have not been sufficiently studied. This report describes the case of a 36-year-old woman with NPSLE who exhibited severe cognitive dysfunction and affective psychosis with persistent nihilistic delusions such as those described in the Cotard delusion. The patient insisted for several months that she was already dead. CSF analysis showed elevated levels of anti-ribosomal P antibodies and a positive determination of oligoclonal bands. Additionally, 18F-FDG PET/CT imaging revealed severe bilateral frontal hypermetabolism suggestive of brain inflammation and occipital hypometabolism. Results from the Systematic Lupus Erythematosus Disease Activity Index 2000 and the Systemic Lupus Erythematosus Disease Activity Score were consistent with an active state of the immunological disease. We then determined by an algorithm that this neuropsychiatric event could be attributed to the activity of the underlying immunological disease. Despite immunosuppressive and symptomatic treatment, only a partial improvement in cognition was achieved. The psychopathological features of the Cotard delusion remained unchanged 4 months after onset. However, we observed rapid remission of affective psychosis and significant improvement in cognition following electroconvulsive therapy. Subsequent follow-up examinations showed a sustained remission. This case describes a protracted form of the Cotard delusion, the diagnostic challenges that arise in the context of SLE, and treatment dilemmas that necessitate collaboration between neurology, psychiatry, and rheumatology.

Abstract
Autoimmune encephalitis is a relatively novel nosological entity characterized by an immune-mediated damage of the central nervous system. While originally described as a paraneoplastic inflammatory phenomenon affecting limbic structures, numerous instances of non-paraneoplastic pathogenesis, as well as extra-limbic involvement, have been characterized. Given the wide spectrum of insidious clinical presentations ranging from cognitive impairment to psychiatric symptoms or seizures, it is crucial to raise awareness about this disease category. In fact, an early diagnosis can be dramatically beneficial for the prognosis both to achieve an early therapeutic intervention and to detect a potential underlying malignancy. In this scenario, the radiologist can be the first to pose the hypothesis of autoimmune encephalitis and refer the patient to a comprehensive diagnostic work-up - including clinical, serological, and neurophysiological assessments.In this article, we illustrate the main radiological characteristics of autoimmune encephalitis and its subtypes, including the typical limbic presentation, the features of extra-limbic involvement, and also peculiar imaging findings. In addition, we review the most relevant alternative diagnoses that should be considered, ranging from other encephalitides to neoplasms, vascular conditions, and post-seizure alterations. Finally, we discuss the most appropriate imaging diagnostic work-up, also proposing a suggested MRI protocol.

Abstract
Anti-N-methyl-D-aspartate receptor-associated encephalitis (NMDARE) is a rare immune-mediated neuroinflammatory condition characterized by the rapid onset of neuropsychiatric symptoms and autonomic dysfunction. The mechanism of pathogenesis remains incompletely understood, but is thought to be related to antibodies targeting the GluN1 subunit of the NMDA receptor with resultant downstream dysregulation of dopaminergic pathways. Young adults are most frequently affected; the median age at diagnosis is 21 years. There is a strong female predilection with a female sex predominance of 4:1. NMDARE often develops as a paraneoplastic process and is most commonly associated with ovarian teratoma. However, NMDARE has also been described in patients with small cell lung cancer, clear cell renal carcinoma, and other benign and malignant neoplasms. Diagnosis is based on correlation of the clinical presentation, electroencephalography, laboratory studies, and imaging. Computed tomography, positron emission tomography, and magnetic resonance imaging are essential to identify an underlying tumor, exclude clinicopathologic mimics, and predict the likelihood of long-term functional impairment. Nuclear imaging may be of value for prognostication and to assess the response to therapy. Treatment may involve high-dose corticosteroids, intravenous immunoglobulin, and plasma exchange. Herein, we review the hallmark clinicopathologic features and imaging findings of this rare but potentially devastating condition and summarize diagnostic criteria, treatment regimens, and proposed pathogenetic mechanisms.

Abstract
Paraneoplastic neurologic syndromes (PNSs) are rare in pediatrics and are understood to be consequences of cross-reactivity against various neuroendocrine antigens expressed on cancer cells. Here, we report a case of autoimmune encephalitis, a type of PNS associated with a case of adrenocortical carcinoma (ACC), that had a clinical response to immunosuppressive therapy. ACC is a rare tumor with controversial tissue of origin but expresses various neuroendocrine antigens that could be the possible mechanism for this rare yet interesting association.

Abstract
OBJECTIVE To identify the timelines of magnetic resonance imaging (MRI) abnormalities and their relationships with the clinical outcomes of patients with new-onset refractory status epilepticus (NORSE). METHODS This retrospective observational study enrolled patients with NORSE who were admitted from March 2008 to July 2018. MRI abnormalities were analyzed visually with the readers blinded to the clinical characteristics of the patients. Poor functional outcome was defined as a Glasgow Outcome Scale score ≤ 3 at discharge. Subsequent pharmacoresistant epilepsy was defined as seizures not controlled by two or more anti-seizure medications 6 months after discharge. RESULTS Among 39 patients with NORSE, 32 (82.1%) exhibited an MRI abnormality. The most common abnormalities were persisting mesial temporal lobe signal abnormality (51.3%); initial diffuse leptomeningeal enhancement within 16 days from seizure onset (15/35, 42.9%); and hippocampal atrophy, which started to appear 26 days after seizure onset (15/26, 57.7%). Only three patients had claustrum abnormalities. Patients with insular involvement had longer treatment delay than those without (24.0 vs 5.5 hours, respectively, P = .02). Duration of status epilepticus (SE) tended to have a linear association with hippocampal atrophy (P = .055). Patients with diffuse leptomeningeal enhancement were more likely to have a poor functional outcome and to develop subsequent pharmacoresistant epilepsy than those without this finding (93.3% vs 15.0%, P < .001; 75.0% vs 22.2%, P = .004, respectively); the results were significant even after adjusting for age, sex, and duration of SE. Hippocampal atrophy and diffuse cortical atrophy were also significantly associated with poor functional outcomes (P = .001 and P = .002, respectively), and patients with these conditions were more likely to develop subsequent pharmacoresistant epilepsy than those without these conditions, after adjusting for age and sex (P = .035 and P = .048, respectively), but not after adjusting for duration of SE. SIGNIFICANCE Initial diffuse leptomeningeal enhancement and later hippocampal atrophy were associated with a poor functional outcome and subsequent pharmacoresistant epilepsy.
