Maple syrup urine disease Radiology Case Radiopaedia

Background: Maple syrup urine disease (MSUD) is secondary to a deficiency of deshydrogenase complex of a cetoacid of branched-chain. This disease has a recessive autosomic inheritance, with an incidence of 1/185,000 newborns [1], without differences between male and female Maple syrup urine disease (MSUD) is a rare autosomal-recessive disorder that affects branched-chain amino acid (BCAA) metabolism. It is characterized by accumulation of BCAAs and corresponding branched-chain keto acids of leucine, isoleucine, and valine in plasma, urine, and cerebrospinal fluid Purpose: We aimed to evaluate the magnetic resonance imaging (MRI) and clinical features of maple syrup urine disease (MSUD). Methods: This retrospective study consisted of 10 MSUD patients confirmed by genetic testing. All patients underwent brain MRI Maple syrup urine disease: diffusion MRI, and proton MR spectroscopy findings A 7-month-old boy is reported with acute metabolic crisis of maple syrup urine disease. A reversible intramyelinic type of edema was noted by diffusion MRI which completely resolved in 3 months in accordance with good clinical outcome Tandem mass spectroscopy showed elevated branched chain amino acids suggesting maple syrup urine disease (MSUD). MRI on day 14 revealed findings typical of MSUD (figures 1 and 2). The characteristic pattern of restricted diffusion, attributed to intramyelinic edema, corresponds to areas that are myelinating at birth

Ten infants with classical maple syrup urine disease (MSUD) and two with variant MSUD had a total of 26 CT scans and 13 MR examinations of the brain during different stages of their disease. We found that inter- and intrapatient analyses of CT and MR findings at times ranging from 3 days to 7 months were typical enough to suggest the MSUD diagnosis Ten infants with classical maple syrup urine disease (MSUD) and two with variant MSUD had a total of 26 CT scans and 13 MR examinations of the brain during different stages of their disease. We found that inter- and intrapatient analyses of CT and MR findings at times ranging from 3 days to 7 months Author information: (1)Department of Radiology, Bambino Gesu Children's Hospital, Rome, Italy. We performed serial cranial ultrasonography in four newborns affected by maple syrup urine disease. Symmetric increase of echogenicity of periventricular white matter, basal ganglia (mainly pallidi), and thalami was detected in the acute stage Maple syrup urine disease (MSUD) is an autosomal recessive inherited metabolic disorder, caused by branched-chain alpha-ketoacid dehydrogenase (BCKD) deficiency, leading to toxic accumulation of branched-chain amino acids (BCAAs) including leucine, isoleucine and valine and their corresponding a-ketoacids Since 1972, eighteen patients (10 females/8 males) have been detected by newborn bloodspot screening (NBS) with neonatal-onset Maple Syrup Urine Disease (MSUD) in Ireland. Patients were stratified into three clusters according to clinical outcome at the time of data collection, including development

More than 20 instances of maple syrup urine disease (MSUD) have been described since 1954. Most were infants, who manifested in the first month of life a maple syrup odor in their urine and a clinical pattern of fits, episodic rigidity, lethargy, and poor suck. When measured, their blood and urine.. Understanding Maple Syrup Urine Disease What is Maple Syrup Urine Disease (MSUD)? MSUD is a genetic disease that affects your body's natural ability to break down protein. • Our bodies need 20 different building blocks to make protein. These building blocks are called amino acids. They play an important role in building muscles, bone In maple syrup urine disease, when the enzyme is missing, protein cannot be fully broken down for use by the body. Because these amino acids do not get broken down completely, high levels accumulate in the blood, urine and sweat. The byproduct of isoleucine has a characteristic sweet smell, which gives the disorder its name..

Maple syrup urine disease, inherited metabolic disorder involving leucine, isoleucine, and valine (a group of branch chain amino acids). Normally, these amino acids are metabolized, step by step, by a number of enzymes, each of which is specific for each step in the metabolism of each amino acid.One of the metabolic steps consists of the decarboxylation of the α-keto acids of leucine. Maple syrup urine disease is an inherited (genetic) condition that prevents the body from processing proteins correctly. Your body breaks down the protein you eat into parts called amino acids. Your body then uses those amino acids to make other proteins that it needs to function. Certain enzymes break down a specific type of amino acid called branched-chain amino acids
