Concurrent myasthenia gravis and neuromyelitis optica spectrum disorder: a rare intersection of autoimmune pathologies.

This case report describes a woman in her 50s with a rare coexistence of neuromyelitis optica spectrum disorder (NMOSD) and myasthenia gravis (MG), highlighting the diagnostic challenges and therapeutic considerations. Initially diagnosed with acetylcholine receptor antibody-positive MG, she later developed progressive visual impairment, leading to a diagnosis of NMOSD. Rituximab treatment was effective in managing both conditions, demonstrating the benefits of targeted therapies in reducing complications related to polypharmacy.

Beyond conventional therapies: IVIG in treating severe fingolimod-rebound in a postpartum patient with MS.

This case report details a female patient with multiple sclerosis in her 30s, who experienced a significant fingolimod rebound syndrome post partum, characterised by worsening neurological symptoms and severe demyelinating lesions. Traditional treatments, including steroids and plasmapheresis, were ineffective.
