A case of neuropsychiatric lupus Erythematosus characterized by the Owl's eye sign: a case report

The Discrepancy of ANA and Compartment Bead Patterns Suggestive of a Neuropsychiatry Systemic Lupus Erythematosus (NPSLE)

Neuropsychiatric systemic lupus erythematosus (NPSLE) exhibits neurological and psychiatric manifestations in systemic lupus erythematosus (SLE) patients, which NPSLE diagnosis can be challenging for rheumatologists. An Indonesian female, 44 years old, complained of two times seizures with 10-min duration, which during seizures were stiff, eyes rolled up, foaming at the mouth, wet the bed, and fainting afterward. The patient also has a history of SLE and received cyclophosphamide therapy 5 years ago. Her clinical condition showed facial and lingual palsy, with central type on the right. Antinuclear antibody indirect immunofluorescence (ANA IF) positive using cytobead ANA with a homogenous pattern and cytoplasmic speckled titer 1/80. Confirmation beads showed positive of dsDNA only. ANA profile showed positive antinucleosome, antihistone, and AMA-M2, and also increased anticardiolipin antibody that supports the diagnosis of NPSLE. The difference in the pattern of ANA IF with confirmation beads suggests the presence of other autoantibodies in NPSLE.

A Longitudinally Extensive Spinal Cord Lesion Restricted to Gray Matter in an Adolescent Male

Longitudinally extensive spinal cord lesions (LECL) restricted to gray matter are poorly understood as are their neurodevelopmental repercussions in children. We herein report the critical case of a 13-year-old male presenting with progressive quadriparesis found to have cervical LECL restricted to the anterior horns. Challenged with a rare diagnostic dilemma, the clinical team systematically worked through potential vascular, genetic, infectious, rheumatologic, and paraneoplastic diagnoses before assigning a working diagnosis of acute inflammatory myelopathy. Nuanced consideration of and workup for both potential ischemic causes (arterial dissection, fibrocartilaginous embolism, vascular malformation) and specific inflammatory conditions including Transverse Myelitis, Neuromyelitis Optica Spectrum Disorders (NMOSD), Multiple Sclerosis (MS), Acute Disseminated Encephalomyelitis (ADEM), and Acute Flaccid Myelitis (AFM) is explained in the context of a comprehensive systematic review of the literature on previous reports of gray matter-restricted longitudinally extensive cord lesions in children. Treatment strategy was ultimately based on additional literature review of treatment-refractory acute inflammatory neurological syndromes in children. A combination of high-dose steroids and plasmapheresis was employed with significant improvement in functional outcome, suggesting a potential benefit of combination immune-modulatory treatment in these patients. This case furthermore highlights quality clinical reasoning with respect to the elusive nature of diagnosis, nuances in neuroimaging, and multifocal treatment strategies in pediatric LECL.

A Brain Ring-Enhancing Lesion

Neuropsychiatric systemic lupus erythematosus (NPSLE) presents a diagnostic challenge as there is no unified pathophysiological process driving its presentation. Case reports are limited in detailing manifestations and outcomes of NPSLE. This case highlights a unique presentation of NPSLE and discusses challenges associated with diagnosis. A 27-year-old man with systemic lupus erythematosus presented with altered mentation. Initial laboratory results and computed tomography of the brain were unremarkable, but magnetic resonance imaging of the brain revealed ring-enhancing lesions reported as NCC. This led to an extensive infectious disease evaluation, but ultimately there was no evidence of infection. The patient was diagnosed with NPSLE; treatment with intravenous glucocorticoids and cyclophosphamide led to dramatic clinical improvement. Repeat brain magnetic resonance imaging showed resolution of the ringed lesions. This case illustrates the importance of thorough evaluation in immunocompromised patients and warns of the risk of anchoring bias that can lead to diagnostic delays.
