Systemic lupus erythematosus with autoimmune neurological manifestations in a carrier of chronic granulomatous disease - a rare presentation.

Chronic granulomatous disease (CGD) is an uncommon genetic immunodeficiency disorder affecting neutrophil function, characterized by recurrent bacterial and fungal infections. X-linked carriers of CGD have an increased risk of autoimmune disorders, in particular lupus like disorders. We describe the case of a 37 years old female carrier of X-linked CGD, who presented with clinical features and serology consistent with a definite diagnosis of Systemic lupus erythematosus (SLE), with rare immune mediated neurological manifestations including secondary central nervous system (CNS) vasculitis and Longitudinally extensive transverse myelitis (LETM), responsive to immunomodulation.
