Background. Developmental disorders are failure or inability to acquire various age-specific skills at expected maturational age, which affects about 5–10% of preschool children. One of the most important methods for evaluation of developmentally delayed children is neuroimaging, especially, brain magnetic resonance imaging (MRI) that provides useful information regarding brain tissue structures and anomalies.Method and Material. In this study, hospital records of 580 developmentally delayed children (aged 2 months to 15 years) who admitted in pediatric ward of Golestan Hospital from 1997 to 2009 were selected. Information such as age, MRI findings were collected in the questionnaire and statistically analyzed.Results. Total, 580 children including 333 males (57.4%) and 247 females (42.6%) were studied. Abnormal brain MRI was observed in 340 (58.6%) cases (204 Males, 136 females). The finding includes nonspecific in 38 (6.6%), congenital and developmental anomalies of brain in 39 (6.7%), recognizable syndromes in 3 (0.5%), neurovascular diseases or trauma in 218 (37.6%), and metabolic or neurodegenerative diseases in 42 (7.2%) cases.Conclusion. Because 60% of all study groups showed abnormal brain MRI, using this method could be effective in diagnosis, management, and almost prognosis determination processes.

The goal of this study was to elucidate radiologic biomarker that can predict the outcome of cochlear implantation (CI) in congenital cytomegalovirus (cCMV) related deafness. A retrospective survey of speech perception after CI and an evaluation of brain magnetic resonance imaging (MRI) findings were performed in 10 cochlear implantees with cCMV-related prelingual deafness. Specifically, a special attention was paid to the degree of white matter (WM) abnormality shown in brain MRI, which was used to divide our cohort into two groups: The mild and severe pathology groups. Age-matched prelingual deaf patients with idiopathic sensorineural hearing loss were selected as controls. Subjects in mild pathology groups showed higher a Category of Auditory Performance (CAP) score (5.2 ± 0.8) than those with severe pathologies (3.4 ± 1.5) (P = 0.041). Importantly, speech performance from subjects with mild pathology was comparable to that of the control group (mean CAP score of 5.2 ± 0.8 vs. 5.1 ± 1.2) (P = 0.898). Mild pathologies related to the limited WM lesion in MRI not accompanied by severe MRI pathologies, such as diffuse WM abnormality, myelination delay, ventriculomegaly, migration abnormality, and cerebellar hypoplasia, can be tolerated and do not adversely affect the CI outcome in cCMV deafness.

Introduction: In neonatal period, brain magnetic resonance imaging (MRI) is the best neuroimaging to find etiology of seizure. The aim of this study was to evaluate brain MRI findings of neonates with clinical seizure and its effect on diagnostic and therapeutic interventions of newborn. Methods: In a retrospective study, medical records and brain MRI findings of neonates with clinical seizure admitted to Neonatal Intensive Care Unit or Pediatric Ward of Shahid Sadoughi Hospital, Yazd, Iran from September 2018 and before were evaluated. The data were analyzed using SPSS version 16 software , the required indicators and tables were prepared and Fisher exact test and Chi-square test were used to determine the relationship between qualitative variables and independent t-test was used to compare the means in the two groups Results: Twenty-five girls and 38 boys were studied. The cause of seizures was found in 94% and the most common cause of congenital hypoxia was in 22 infants (35%). The most common type of seizure was tonic in 23 infants (36.5%) and the most common type of generalized seizure was in 47 infants (75%). Brain MRI was abnormal in 19 neonates (30%). Based on the MRI results, there was a change in therapeutic interventions (brain surgery) in four infants (6.3%) and in diagnostic interventions (metabolic tests) in 19 infants (30%). Abnormal brain MRI was more frequent in neonates by cesarean section (46%)  than  normal vaginal delivery (19%), (p= 0.01) and also neonates with partial seizure (37.5%) had an abnormal MRI than  generalized seizure (21%), (p= 0.03). Mean of hospitalization days was longer in neonates with abnormal brain MRI (12.32±2.76 days) than neonates with normal MRI (8.57±2.82 days) (P = 0.02). Conclusion: Based on the results of this study, brain MRI might be useful in finding intracranial pathology that causes seizure in neonates by cesarean section to detect birth asphyxia and in newborns with partial seizure.

Global developmental delay / intellectual disability are common pediatric conditions. Brain magnetic resonance imaging (MRI), although an important diagnostic tool in the evaluation of these patients, often requires general anesthesia. Recent literature suggests that unnecessary general anesthesia exposure should be avoided in early years because of possible long-term negative neurodevelopmental sequelae. This study sought to identify clinical clues associated with brain MRI abnormalities in children with global developmental delay / intellectual disability in an attempt to provide guidance to physicians on selecting patients who would benefit from an MRI. Retrospective chart review analysis was conducted for patients presenting to a pediatric neurology tertiary care center between 2014 and 2017 for a first clinic evaluation for global developmental delay / intellectual disability. Detailed clinical history and physical examination findings were analyzed and correlated with brain MRI findings. The majority (218/327, 67%) of children referred for evaluation of global developmental delay / intellectual disability underwent complete clinical and radiologic evaluations. Mean age was 37.9 months (±32.5 standard deviation) and 116 were males (53%). Motor deficits were predominant in most subjects (122/218, 56%). Abnormal MRI findings were observed in 153 children (70%), with the most prevalent abnormalities noted within the white matter (104/153, 68%), corpus callosum (77/153, 50%), and the hippocampus (50/153, 33%). Abnormal MRI findings were prevalent in children with predominant motor delay (84, 69%) and cognitive disability (3, 100%) as well as those with visual and hearing impairment ( P < .05). The presence of facial dysmorphisms (57/71, P = .02); cranial nerve abnormalities (79/100; P = .007) and abnormal reflexes (16, P = .01) on examination also correlated significantly with increased MRI abnormalities.

Few Data

In the present study, the results of brain magnetic resonance imaging (MRI) in girls with central precocious puberty (CPP) were compared those in with girls evaluated for headaches. A total of 295 girls with CPP who underwent sellar MRI were enrolled. A total of 205 age-matched girls with chronic or recurrent headaches without neurological abnormality who had brain MRI were included as controls. The positive MRI findings were categorized as incidental non-hypothalamic–pituitary (H–P), incidental H–P, or pathological. Positive MRI findings were observed in 39 girls (13.2%) with CPP; 8 (2.7%) were classified as incidental non-H–P lesions, 30 (10.2%) as incidental H–P lesions, and 1 (0.3%) as a pathological lesion (tuber cinereum hamartoma). The prevalence of positive MRI findings in girls with CPP did not differ from girls with headaches (13.2% vs. 12.2%, p = 0.74). The prevalence of incidental H–P lesions in girls with CPP <6 years of age, 6–6.9 years of age, and 7–7.9 years of age was 21.2%, 13.5%, and 9.6%, respectively (p = 0.21). Known pathological lesions were detected in only one (3.0%) girl with CPP aged <6 years and in no girls with CPP aged 6–7.9 years. Microadenomas were detected in no girls with CPP aged <6 years and in 5 (1.9%) girls with CPP aged of 6–7.9 years. Our findings call into question the routine use of brain MRI in girls with CPP, especially in girls 6 years or older. Current guidelines recommend a follow-up MRI in cases of microadenoma, but few data exist to support this recommendation for children.

Abstract Background We aimed to find the clinical significance of brain abnormalities on magnetic resonance imaging (MRI) in epilepsy and the lateralization of these findings with electroencephalogram (EEG). Methods We retrospectively analyzed the results of all EEGs and brain MRIs of 600 consecutive epilepsy patients from 1998 to 2020. Results Data were available for 563 cases (267 females). Ninety percent of the patients were 18 years old or younger. A total of 345 patients (61.3%) had focal epilepsy, 180 (32%), generalized, and 38 (6.7%), inconclusive. In 187 (33.2%), the first MRI was abnormal and in 81 (out of 108 repeated MRI), the second was pathological. The most frequent brain abnormalities were cortical dysplasia in 41 (18.1%), other structural abnormalities in 25 (11%), various phacomatoses in 23 (10.1%), and mesial temporal sclerosis in 17 (7.5%). Among 226 patients with abnormal MRI, 171 (75.6%) had focal epilepsy when compared with 36 (15.9%) with generalized epilepsy (p <0.001). In 121 patients (53.5%), the result of the abnormal MRI contributed significantly to the understanding of the epilepsy etiology. The side of abnormality was lateralized to the EEG focus in 120 cases (53%); in 10/15 cases with infantile spasms (66%), MRI was significantly abnormal. In 33, in whom the first MRI was normal, a second MRI revealed a significant abnormality. Conclusion Brain MRI is an important tool in epilepsy diagnosis, mainly in focal seizures and infantile spasms. A repeat MRI is mandatory in intractable focal cases to improve the yield of this test.

TÓM TẮT U mỡ trong xương là khối u lành tính hiếm gặp, thường gặp ở các xương dẹt, hiếm gặp ở xương nền sọ, đặc biệt là xương bướm. Trong đa số các trường hợp, u mỡ trong xương bướm thường được phát hiện tình cờ qua chụp cắt lớp vi tinh (CLVT) hoặc cộng hưởng từ (CHT) sọ não. Đây là một khối u phát triển chậm, ít gây ra triệu chứng, một số trường hợp gây triệu chứng khi khối u to chèn ép vào cấu trúc lân cận như tuyến yên hoặc dây thần kinh thị. Trong bài này, chúng tôi báo cáo một trường hợp u mỡ trong xương bướm không triệu chứng được phát hiện tình cờ và được chẩn đoán dựa vào phim chụp cộng hưởng từ sọ não. Bệnh nhân được khuyến nghị theo dõi định kỳ bằng cộng hưởng từ mà không phải tiến hành bất kỳ phương pháp điều trị nào. Từ khóa: U mỡ, xương bướm, MRI, cộng hưởng từ sọ não, chẩn đoán hình ảnh. ABSTRACT INTRAOSSEOUS LIPOMA OF SPHENOID BONE: A RARE CASE REVIEW Intraosseous lipoma is very rare, usually benign tumor of flat bones. The incidence of an intraosseous lipomalocated basal skull bones is extremely rare, especially in sphenoid bone. Radiological imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) are used to detect the intraosseous lipoma by accident. These tumors are slow growing and usually asymptomatic, in some cases causing symptoms when the large tumor presses on nearby structures such as pituitary gland or the optic nerve. We present a rare case of lipomaof the sphenoid bone discovered incidentally with brain magnetic resonance imaging. The patient has been followed-up by magnetic resonance imaging without the need for surgery. Keywords: Intraosseous lipoma, sphenoid bone, MRI, brain MRI, diagnostic radiology

Abstract 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 ?-ketoacids. The diagnosis of MSUD is based on elevated BCAAs and allo-isoleucine in plasma, and branched-chain hydroxyacids and ketoacids in urine. The identification of alloisoleucine >5 µmol/L is considered pathognomonic. Moreover, brain magnetic resonance imaging (MRI) showing atypical signal intensity and oedema is characteristic of MSUD. Recognition of the classical neuro-radiological findings of MSUD is particularly useful in local settings as many healthcare facilities lack the resources to measure Plasma Amino Acids (PAA). We report three cases of MSUD, in whom the disorder was strongly suspected at presentation, based on classical brain MRI findings, which was urgently confirmed by PAA analysis Continuous...

ABSTRACT Purpose: To evaluate the contribution of conventional brain magnetic resonance imaging (MRI) for the determination of intracranial aneurysms. Materials and Methods: Brain MRI and computed tomography angiography (CTA) of 45 patients (29 women and 16 men; age range, 32–80 years) with aneurysm were analyzed. A comparison was made between brain MRI and CTA based on size and presence of aneurysm. The comparisons between MRI and CTA were investigated through Bland-Altman graphics, receiver operating characteristic curve, and Kappa statistics. Results: Fifty-seven aneurysms were evaluated. Forty-five percent of 57 aneurysms on CTA were detected on conventional brain MRI. A significant correlation was found between CTA and brain MRI in the diagnosis of aneurysm (P < 0.05). In an analysis of the size measurement, a significant correlation was observed between CTA and brain MRI. Seventy-seven percent of aneurysms <4 mm was not detected and the efficiency of MRI in the detection of aneurysms <4 mm was found to be low. Conclusion: Aneurysms can also be appreciated on conventional brain MRI, and vascular structures should be reviewed carefully while analyzing brain MRI.
