We present a 47-year-old white woman who had a definitive diagnosis of systemic lupus erythematosus (SLE), and developed cerebellar ataxia of sudden onset. MR imaging showed changes characteristics of cerebellar infarct. Due to the absence of vascular risk factors and to the previous diagnosis of SLE, we postulate that the cerebellar infarct is related to SLE. We are not aware of previous descriptions of the MRI findings in lupus ataxia.

We report the case of a 24-year-old woman with systemic lupus erythematosus (SLE). The patient presented with cervical erythema and multiple arthralgia in December, 1996. Based on the high level of antinuclear antibody and the positivity for anti-double-stranded-DNA antibody, we diagnosed the patient as having SLE. Her symptoms improved and her condition was maintained following steroid treatment. In August 2000, the patient suddenly had headache, nausea, vertigo, cerebellar ataxia, fixation nystagmus, and intention tremor. She was negative for the anti-phospholipid antibody. The cerebrospinal fluid IgG index and the IL-6 level were high. MRI of the right cerebellar hemisphere showed an equal-signal-intensity region in the T 1-enhanced image, and a high-signal-intensity region with a diffuse undefined border in the T 2-enhanced image. The increased cerebral blood flow at the site corresponding to a cerebellar lesion detected by magnetic resonance imaging (MRI) was observed by brain single photon emission computed tomography (SPECT). The central nervous system (CNS) lupus was confirmed by the presence of a lesion in the cerebellum. The abnormalities detected in MRI and SPECT images of the brain disappeared immediately after the steroid pulse therapy, and symptoms such as ataxic gait were improved. This patient was diagnosed as having acute neuropsychiatric SLE with cerebellar symptoms that are rarely observed as a localized neural sign of SLE. The MRI and SPECT images suggested the presence of an inflammatory edematous lesion that was confined in the cerebellar hemisphere. This is considered to be due to the increase of vasopermeability.

Neuropsychiatric manifestations are commonly observed in systemic lupus erythematosus (SLE) patients; however, cerebellar involvement has rarely been reported. In the presence of acute cerebellar ataxia, etiologies related (focal edema and ischemia) and not related (infections, malignancy and paraneoplastic syndromes) to lupus have to be considered and they imply different treatment strategies. We report the clinical and radiological features of 3 SLE patients who presented with acute cerebellar ataxia. A review of the literature was performed by documenting cases of cerebellar ataxia in SLE and the importance of neuroimaging in the evaluation of these patients.

Acute cerebellar ataxia in patients with lupus is rare and occurs early in the course of disease. We report a case of acute cerebellar ataxia in a young adult female who recovered completely with intravenous high-dose steroid therapy.

Subacute cerebellar ataxia in combination with cerebellar atrophy has rarely been reported as one of the manifestations of lupus in the central nervous system (CNS). We describe a 27-year-old woman with systemic lupus erythematosus who developed subacute cerebellar ataxia. Computed tomography and magnetic resonance imaging of her brain showed cerebellar atrophy in both hemispheres, particularly on the right side. Moreover, increased antineuronal cell antibody levels were detected in her cerebrospinal fluid. The cerebellar ataxia improved markedly following high-dose corticosteroid administration. This suggests that a relationship exists between autoantibodies and subacute atrophic processes in CNS lupus.

A 59-year-old woman who had been diagnosed with systemic lupus erythematosus (SLE) was admitted to our hospital due to paralysis in all of her limbs. The patient presented with dysarthria, cerebellar ataxia and hypoxia. Magnetic resonance imaging (MRI) revealed vasogenic edema in the brain stem and the cerebellum. She was diagnosed with neuropsychiatric lupus syndrome (NPSLE) and pulmonary arterial hypertension (PAH), and was successfully treated using immunosuppressive therapy. To our knowledge, this is the first reported case of simultaneously developing NPSLE and PAH.

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.

<i>Inherited neurodegenerative disorders are debilitating diseases that occur across different species, such as the domestic dog (Canis lupus familiaris), and many are caused by mutations in the same genes as corresponding human conditions. In the present study, we report an inherited neurodegenerative condition, termed 'neuronal vacuolation and spinocerebellar degeneration' (NVSD) which affects neonatal or young dogs, mainly Rottweilers, which recently has been linked with the homozygosity for the RAB3GAP1:c.743delC allele. Mutations in human RAB3GAP1 cause Warburg micro syndrome (WARBM), a severe developmental disorder characterized predominantly by abnormalities of the nervous system including axonal peripheral neuropathy. RAB3GAP1 encodes the catalytic subunit of a GTPase activator protein and guanine exchange factor for Rab3 and Rab18 proteins, respectively. Rab proteins are involved in membrane trafficking in the endoplasmic reticulum, autophagy, axonal transport and synaptic transmission. The present study attempts to carry out a detailed histopathological examination of NVSD disease, extending from peripheral nerves to lower brain structures focusing on the neurotransmitter alterations noted in the cerebellum, the major structure affected. NVSD dogs presented with progressive cerebellar ataxia and some clinical manifestations that recapitulate the WARBM phenotype. Neuropathological examination revealed dystrophic axons, neurodegeneration and intracellular vacuolization in specific nuclei. In the cerebellum, severe vacuolation of cerebellar nuclei neurons, atrophy of Purkinje cells, and diminishing of GABAergic and glutamatergic fibres constitute the most striking lesions. The balance of evidence suggests that the neuropathological lesions are a reaction to the altered neurotransmission. The canine phenotype could serve as a model to delineate the disease-causing pathological mechanisms in RAB3GAP1 mutation. </i>.

Neuropsychiatric manifestations are commonly observed in systemic lupus erythematosus (SLE) patients. In particular, neurological involvement is known to be more common in patients with positive anticardiolipin antibodies and lupus anticoagulants. Nevertheless, cerebellar ataxia has rarely been reported, especially as the first clinical manifestation of this systemic autoimmune disorder. Cerebral vascular infarction or ischemia, vasogenic oedema and antibody-mediated cerebral vasculopathy or vasculitic process have been supposed as possible aetiologies of acute cerebellar ataxia related to SLE. We report the clinical and radiological features of a woman who developed a rapidly progressive cerebellar syndrome as first sign of SLE; no other cause explaining her cerebellar ataxia was found. The patient improved after high-dose steroids. The appearance of a cerebellar syndrome with unknown aetiology with associated features of possible systemic autoimmune dysfunction, should be taken into account in clinical practice for appropriate diagnostic workup in order to provide effective therapeutic options.
