Tumefactive demyelinating lesions: A literature review of recent findings.

Tumefactive demyelinating lesion is a variant of multiple sclerosis that is a diagnostic challenge. Tumefactive demyelinating lesion requires extensive work-up as its clinical and radiological features are often indistinguishable from other central nervous system lesions, such as tumors. Diagnosis is further complicated by the increasing recognition that tumefactive demyelinating lesions can occur alongside, evolve into, or develop from numerous conditions other than multiple sclerosis, pointing to a possible overlapping etiology.

The prevalence of major depression and generalized anxiety disorder in patients with multiple sclerosis in Saudi Arabia: a cross-sectional multicentered study.

Background: Multiple sclerosis (MS) is an autoimmune disease characterized by chronic, progressive neurodegeneration of the central nervous system (CNS), and it is the most common inflammatory neurological disease affecting young adults. Given the chronic, progressive nature of the disease, psychiatric disorders are more prevalent among these patients, as reported in the literature; however, data in Saudi Arabia are limited. This study aimed to estimate the prevalence of major depression and generalized anxiety disorder in patients with MS and their association with different patient demographics.

Saudi consensus recommendations on the management of Neuromyelitis Optica Spectrum Disorders (NMOSD).

This article focuses on the diagnosis and management of neuromyelitis optica spectrum disorder (NMOSD). NMOSD is an autoimmune, demyelinating condition characterized by inflammation of the optic nerve and/or the spinal cord, with symptoms that can range from mild impairment of movement to paralysis. The newly approved diagnostic criteria have improved the accuracy of NMOSD diagnosis.

Saudi consensus recommendations on the management of multiple sclerosis: MS management in children and adolescents.

Multiple sclerosis (MS) most commonly presents in young adults, although 3-5% of patients develop MS prior to the age of 18 years. The new and comprehensive consensus for the management of MS in Saudi Arabia includes recommendations for the management of MS and other CNS inflammatory demyelinating disorders in pediatric and adolescent patients. This article summarizes the key recommendations for the diagnosis and management of these disorders in young patients.

Isolated neurosarcoidosis mimicking multiple sclerosis.

Patients with isolated neurosarcoidosis (NS) can present with neurological symptoms that mimic other neurologic conditions, such as multiple sclerosis (MS). In this article, we present a case of 25-year-old man with a transverse myelitis. Magnetic resonance imaging (MRI) of the brain and spine showed several, periventricular, infratentorial, and spinal cord white matter lesions.

Alemtuzumab-induced simultaneous onset of autoimmune haemolytic anaemia, alveolar haemorrhage, nephropathy, and stroke: A case report.

Background: Alemtuzumab is a humanized anti-CD 52 monoclonal antibody approved as a disease-modifying therapy for active relapsing-remitting Multiple Sclerosis (MS). Alemtuzumab has been associated with several adverse effects, including infusion-associated reactions, infections, acquired autoimmune diseases, and malignancies.

Case Presentation: We report a case of Alemtuzumab-induced simultaneous onset of autoimmune haemolytic anaemia, alveolar haemorrhage, nephropathy and stroke in a 52-year-old man that occurred 8 months after initiation of alemtuzumab.

Delayed tacrolimus-induced optic neuropathy.

Tacrolimus is an immunosuppressant agent utilized for solid organ transplantations. It has been associated with rare neurotoxic effects. This case highlights one possible delayed neurotoxic effect.
