Lupus Cerebellitis Presenting With Ataxia: A Case Report

We report a case of a woman with a history of systemic lupus erythematosus who developed persistent ataxia and was diagnosis with lupus cerebellitis. Magnetic resonance imaging of the brain showed T2/FLAIR signal hyperintensity within the cerebellar vermis without mass effect. The patient's condition improved with pulse IV methylprednisolone. This case highlights unique imaging findings within the cerebellum, our diagnostic and treatment regimen, and compares this case to previous literature on similar cases.

Movement disorders in systemic autoimmune diseases: Clinical spectrum, ancillary investigations, pathophysiological considerations

With the advances in neuroimmunology especially due to the discovery of new neuronal antibodies, the recognition of treatable antibody-related movement disorders has recently received much attention. In contrast, the identification and characterisation of movement disorders associated with systemic autoimmune diseases remains a substantially unexplored area. Beyond the classic few associations such as chorea and antiphospholipid syndrome, or ataxia and coeliac disease, movement disorders have been reported in association with several systemic autoimmune diseases, however a clear image of clinical phenotypes, investigations, and treatment outcomes in these conditions has never been drawn. In this review, we analyse data from approximately 300 cases and summarise the epidemiological, clinical and diagnostic features of movement disorders associated with systemic autoimmune diseases, and the available knowledge about treatment and outcomes. We highlight that movement disorders in systemic autoimmune conditions are frequently the only or among a few presenting manifestations and are mostly treatable disorders responding to immunotherapy or dietary modifications. We point out the pertinent combination of clinical features and investigations which can suggest the underlying autoimmune nature of these movement disorders, and thus address the most appropriate treatment.

Cerebellar ataxia as a primary manifestation of neuropsychiatric systemic lupus erythematosus

Acute cerebellar ataxia is a rare primary manifestation of neuropsychiatric systemic lupus erythematosus (NPSLE). We report a case of a 22-year-old woman who presented with gait instability, behavioural changes and new-onset seizures. The tempo of disease progression was explained by an autoimmune cause, eventually fulfilling the criteria for systemic lupus erythematosus. The patient's neurological symptoms improved markedly following administration of steroids and immunomodulators. A review of literature on cerebellar ataxia in NPSLE and a summary of all reported cases to date are also presented.

Functional Improvement after Taking Rehabilitation Program in Cerebellar Ataxia in a Patient with Systemic Lupus Erythematosus: a Case Report

Cerebellar involvement in systemic lupus erythematosus (SLE) is rare, occurring in less than 2% of cases, with cerebellar atrophy on brain imaging even rarer. We describe a case of cerebellar atrophy in a patient with a history of SLE who underwent an intensive rehabilitation program and achieved functional improvement. A 26-years-old female with SLE felt difficult in balancing as well as dizziness and she took magnetic resonance imaging which showed cerebellar atrophy and positron emission tomography-computed tomography which showed markedly decreased signal intensity at bilateral temporal, parietal lobes, cerebellum and moderately at bilateral frontal lobes. A neurological examination showed bilateral nystagmus, intention tremor, bilateral dysmetria, and bilateral dysdiadochokinesia. Prior to the rehabilitation program, the patient's scores on the Berg Balance Scale (BBS) and Modified Barthel Index (MBI) were 4/56 and 37/100, respectively. The patient was hospitalized twice for rehabilitation treatment, which consisted of physical therapy, occupational therapy, therapeutic pool therapy, and robotic-assisted gait training. At discharge, the patient's BBS score was 9/56, and her MBI score was 46/100, and she was able to walk more than 20 m using an anterior walker. In the final 2 weeks before discharge, the patient was trained in the use of an electric wheelchair for outdoor activity.

Movement and Other Neurodegenerative Syndromes in Patients with Systemic Rheumatic Diseases: A Case Series of 8 Patients and Review of the Literature

Patients with rheumatic diseases can present with movement and other neurodegenerative disorders. It may be underappreciated that movement and other neurodegenerative disorders can encompass a wide variety of disease entities. Such disorders are strikingly heterogeneous and lead to a wider spectrum of clinical injury than seen in Parkinson's disease. Therefore, we sought to stringently phenotype movement and other neurodegenerative disorders presenting in a case series of rheumatic disease patients. We integrated our findings with a review of the literature to understand mechanisms which may account for such a ubiquitous pattern of clinical injury.Seven rheumatic disease patients (5 Sjögren's syndrome patients, 2 undifferentiated connective tissue disease patients) were referred and could be misdiagnosed as having Parkinson's disease. However, all of these patients were ultimately diagnosed as having other movement or neurodegenerative disorders. Findings inconsistent with and more expansive than Parkinson's disease included cerebellar degeneration, dystonia with an alien-limb phenomenon, and nonfluent aphasias.A notable finding was that individual patients could be affected by cooccurring movement and other neurodegenerative disorders, each of which could be exceptionally rare (ie, prevalence of ∼1:1000), and therefore with the collective probability that such disorders were merely coincidental and causally unrelated being as low as ∼1-per-billion. Whereas our review of the literature revealed that ubiquitous patterns of clinical injury were frequently associated with magnetic resonance imaging (MRI) findings suggestive of a widespread vasculopathy, our patients did not have such neuroimaging findings. Instead, our patients could have syndromes which phenotypically resembled paraneoplastic and other inflammatory disorders which are known to be associated with antineuronal antibodies. We similarly identified immune-mediated and inflammatory markers of injury in a psoriatic arthritis patient who developed an amyotrophic lateral sclerosis (ALS)-plus syndrome after tumor necrosis factor (TNF)-inhibitor therapy.We have described a diverse spectrum of movement and other neurodegenerative disorders in our rheumatic disease patients. The widespread pattern of clinical injury, the propensity of our patients to present with co-occurring movement disorders, and the lack of MRI neuroimaging findings suggestive of a vasculopathy collectively suggest unique patterns of immune-mediated injury.

Cerebellar ataxia in a young patient: A rare path to lupus

Cerebellar ataxia is a rare manifestation of neuropsychiatric systemic lupus erythematosus (SLE). Development of vasculitic infarcts in the cerebellum is the most plausible reason of this manifestation. We report the case of a patient who presented with characteristic skin rashes of lupus along with cerebellar signs. Imaging of brain in this patient revealed prominent cerebellar atrophy. She was treated with mycophenolate mofetil and oral corticosteroid, and there was no further progression of her neurological signs after the initiation of therapy. In the clinical context of varied presentations of neurolupus, this is one of the rare sightings and our treatment protocol holds promise as first-line therapy in future.
