Unidad de Radiología Pediátrica, Servicio de Radiodiagnóstico, Hospital Universitario y Politécnico La Fe, Valencia, Spain.

Cranial ultrasound (CUS) is an extremely valuable tool to evaluate the brain during the first year of life, in experienced hands. It is the initial screening imaging tool to evaluate the infants' brain and complementary to the use of computed tomography (CT) and magnetic resonance imaging (MRI). It is an accessible, inexpensive and harmless technique that can be used bedside as frequently as needed. Read More

Periventricular leukomalacia: an ophthalmic perspective.

Med J Armed Forces India 2021 Apr 15;77(2):147-153. Epub 2020 Jul 15.

Resident, Department of Ophthalmology, Armed Forces Medical College, Pune, India.

Periventricular leukomalacia (PVL) is a common magnetic resonance imaging (MRI) finding in cases of hypoxic ischemic encephalopathy. PVL, in MRI, is identified by the increased signal intensity of periventricular white matter on T2-weighted sequences which is more conspicuous in the posterior cortex. It occurs because of perinatal damage to the cerebral cortex. Read More

Magnetic Resonance Imaging Findings in Childhood Epilepsy at a Tertiary Hospital in Kenya.

Front Neurol 2021 12;12:623960. Epub 2021 Feb 12.

School of Medicine, Kenyatta University, Nairobi, Kenya.

Neuroimaging is important for determining etiology and guiding care in early childhood epilepsy. However, access to appropriate imaging in sub-Saharan Africa is modest, and as a consequence, etiological descriptions of childhood epilepsy in the region have been limited. We sought to describe MRI findings in children with epilepsy presenting to a tertiary hospital in Nairobi, Kenya, over a 6-year period of routine care. Read More

Department of Radiology, Children's Hospital of Philadelphia, University of Pennsylvania, 3401 Civic Center Blvd., Philadelphia, PA, 19104, USA.

Neurosonography is an essential imaging modality for assessing the neonatal brain, particularly as a screening tool to evaluate intracranial hemorrhage, hydrocephalus and periventricular leukomalacia. The primary advantages of neurosonography include portability, accessibility and lack of ionizing radiation. Its main limitations are intrinsic operator dependence and the need for an open fontanelle. Read More

Laboratory of Neuro Imaging at USC Stevens Neuroimaging and Informatics Institute, Keck School of Medicine of USC, University of Southern California, 2025 Zonal Ave, Los Angeles, CA 90033, USA.

Perinatal brain injuries in preterm neonates are associated with alterations in structural neurodevelopment, leading to impaired cognition, motor coordination, and behavior. However, it remains unknown how such injuries affect postnatal cortical folding and structural covariance networks, which indicate functional parcellation and reciprocal brain connectivity. Studying 229 magnetic resonance scans from 158 preterm neonates (n = 158, mean age = 28. Read More

Routine imaging of the preterm neonatal brain.

Paediatr Child Health 2020 Jun 10;25(4):249-262. Epub 2020 Jun 10.

Canadian Paediatric Society, Fetus and Newborn Committee, Ottawa, Ontario.

Routine brain imaging to detect injuries affecting preterm infants is used to predict long-term outcomes and identify complications that might necessitate an intervention. Although magnetic resonance imaging may be indicated in some specific cases, head ultrasound is the most widely used technique and, because of portability and ease of access, is the best modality for routine imaging. Routine head ultrasound examination is recommended for all infants born at or before 31+6 weeks gestation. Read More

Diagnosis of rhomboencephalosynapsis by MRI in a 5-year-old child.

Radiol Case Rep 2020 Jul 1;15(7):867-870. Epub 2020 May 1.

Radiology department, Shaio Clinic Foundation, University of La Sabana, Bogotá, Colombia.

Rhombencephalosynapsis is a rare defect in the development of the cerebellum, characterized by partial or total agenesis of the vermis, with fusion of the cerebellar hemispheres in the midline. It is usually related to Gómez-López-Hernández Syndrome (cerebellar-trigeminal dermal dysplasia) and VACTERL association (vertebral defects, vascular anomalies, anal atresia, cardiac anomalies, tracheoesophageal fistula with esophageal atresia, renal dysplasia and limb anomalies). A 5-year-old female patient with spastic cerebral palsy and hydrocephalus presented here, neuroimages documented the next features: absence of cerebellar vermis, periventricular leukomalacia, cerebellar tonsils descent and rhombencephalosynapsis.

State-of-the-art neonatal cerebral ultrasound: technique and reporting.

Pediatr Res 2020 03;87(Suppl 1):3-12

Department of Neonatology, Helios Klinikum Berlin Buch, Berlin, Germany.

In the past three decades, cerebral ultrasound (CUS) has become a trusted technique to study the neonatal brain. It is a relatively cheap, non-invasive, bedside neuroimaging method available in nearly every hospital. Traditionally, CUS was used to detect major abnormalities, such as intraventricular hemorrhage (IVH), periventricular hemorrhagic infarction, post-hemorrhagic ventricular dilatation, and (cystic) periventricular leukomalacia (cPVL).

Preterm white matter injury: ultrasound diagnosis and classification.

Pediatr Res 2020 03;87(Suppl 1):37-49

Department of Neonatology, Helios Klinikum Berlin Buch, Berlin, Germany.

White matter injury (WMI) is the most frequent form of preterm brain injury. Cranial ultrasound (CUS) remains the preferred modality for initial and sequential neuroimaging in preterm infants, and is reliable for the diagnosis of cystic periventricular leukomalacia. Although magnetic resonance imaging is superior to CUS in detecting the diffuse and more subtle forms of WMI that prevail in very premature infants surviving nowadays, recent improvement in the quality of neonatal CUS imaging has broadened the spectrum of preterm white matter abnormalities that can be detected with this technique.

Cerebral palsy in children: a clinical overview.

Transl Pediatr 2020 Feb;9(Suppl 1):S125-S135

Hadassah Hebrew University Medical Center, Jarusalem, Israel.

Cerebral palsy (CP) is a disorder characterized by abnormal tone, posture and movement and clinically classified based on the predominant motor syndrome-spastic hemiplegia, spastic diplegia, spastic quadriplegia, and extrapyramidal or dyskinetic. The incidence of CP is 2-3 per 1,000 live births. Prematurity and low birthweight are important risk factors for CP; however, multiple other factors have been associated with an increased risk for CP, including maternal infections, and multiple gestation.

Compound heterozygous mutations in the gene cause Sjögren-Larsson syndrome: a case report.

Int J Neurosci 2020 Nov 29;130(11):1156-1160. Epub 2020 Jan 29.

Department of Neurology, Affiliated Hospital of Jining Medical University, Jining, Shandong, 272000, China.

Sjögren-Larsson syndrome is a rare, autosomal, recessive neurocutaneous disorder caused by mutations in the gene, which encodes the fatty aldehyde dehydrogenase enzyme. Deficiency in fatty aldehyde dehydrogenase results in an abnormal accumulation of toxic fatty aldehydes in the brain and skin, which cause spasticity, intellectual disability, ichthyosis, and other clinical manifestations.

Neuroradiological findings in three cases of pontocerebellar hypoplasia type 9 due to mutation: typical MRI appearances and pearls for differential diagnosis.

Quant Imaging Med Surg 2019 Dec;9(12):1966-1972

Department of Radiology, Great Ormond Street Hospital NHS Foundation Trust, London, UK.

Pontocerebellar hypoplasia type 9 (PCH9) is a rare autosomal recessive neurodegenerative disorder with prenatal onset caused by mutations in adenosine monophosphate deaminase 2 (). PCH9 patients demonstrate severe neurodevelopmental delay with early onset and typical magnetic resonance imaging (MRI) findings consisting in: pontine hypoplasia or atrophy with dragonfly cerebellar atrophy appearance on coronal images, reduction in size of the pons and middle cerebellar peduncles, abnormal midbrain describing a figure of "8" on axial images, diffuse loss of cerebral white matter with striking periventricular leukomalacia (PVL), and absence or extreme thinning of the corpus callosum. A review of the literature on PCH9 shows that the MRI phenotype observed in the series herein presented is similar to the eleven cases of PCH9 previously reported. Read More
