Toxic and Metabolic Disorders

Abstract

AbstractMetabolic diseases are mostly congenital inborn errors leading to functional defects in metabolic pathways, whereas toxic and metabolic diseases in adults are usually acquired. MRI is the cornerstone in the assessment of these patients. The final diagnosis is often established in combination with laboratory findings and/or genetic analysis. Imaging patterns are almost invariably bilateral and often symmetric or nearly symmetric. The basal ganglia and thalami are often involved in acquired metabolic and toxic diseases. This chapter focuses on the most common inborn errors of metabolism that can present or persist into adulthood, as well as on the most common acquired metabolic and toxic disorders, relevant to daily clinical practice.
