RESUMO

BACKGROUND: The cingulate gyrus (CG), a brain structure above the corpus callosum, is recognised as part of the limbic system and plays numerous vital roles. However, its full functional capacity is yet to be understood. In recent years, emerging evidence from imaging modalities, supported by electrical cortical stimulation (ECS) findings, has improved our understanding. To our knowledge, there is a limited number of systematic reviews of the cingulate function studied by ECS. We aim to parcellate the CG by reviewing ECS studies. DESIGN/METHODS: We searched PubMed and Embase for studies investigating CG using ECS. A total of 30 studies met the inclusion criteria. We evaluated the ECS responses across the cingulate subregions and summarised the reported findings. RESULTS: We included 30 studies (totalling 887 patients, with a mean age of 31.8±9.8 years). The total number of electrodes implanted within the cingulate was 3028 electrode contacts; positive responses were obtained in 941 (31.1%, median percentages, 32.3%, IQR 22.2%-64.3%). The responses elicited from the CG were as follows. Simple motor (8 studies, 26.7 %), complex motor (10 studies, 33.3%), gelastic with and without mirth (7 studies, 23.3%), somatosensory (9 studies, 30%), autonomic (11 studies, 36.7 %), psychic (8 studies, 26.7%) and vestibular (3 studies, 10%). Visual and speech responses were also reported. Despite some overlap, the results indicate that the anterior cingulate cortex is responsible for most emotional, laughter and autonomic responses, while the middle cingulate cortex controls most complex motor behaviours, and the posterior cingulate cortex (PCC) regulates visual, among various other responses. Consistent null responses have been observed across different regions, emphasising PCC. CONCLUSIONS: Our results provide a segmental mapping of the functional properties of CG, helping to improve precision in the surgical planning of epilepsy.

RESUMO

Background/aim: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder in children. Determination of risk factors for the development of OSA is essential for early diagnosis and treatment of the disease and decreases the risk of negative consequences. This study aimed to investigate the predictive values of Mallampati score, tonsillar size, and BMI z-score in the presence and severity of OSA in children. Materials and methods: This prospective cross-sectional study included 114 children with OSA symptoms. All children were assessed by BMI z-score, Mallampati score, and tonsillar size and underwent overnight polysomnography. They were consecutively selected and assigned to 4 groups as follows: Group 1 included normal-weight with a low Mallampati score; Group 2 involved normal-weight with a high Mallampati score; Group 3 included obese with a low Mallampati score; and Group 4 involved obese with a high Mallampati score. Results: Of the 114 included children, 58 were female and 56 were male, with a mean age of 13.1 ± 2.9 years. OSA frequency and apnea-hypopnea index were significantly higher in group 4 compared with other groups (p = 0.003 and p < 0.0001, respectively), whereas average and minimum spO2 were significantly lower (for both, p = 0.001). Mallampati score and BMI z-score were found to be significant for predicting OSA (odds ratio = 4.147, 95% CI: 1.440-11.944; p = 0.008 and odds ratio = 1.760, 95% CI: 1.039-2.980; p = 0.035, respectively). Among OSA patients, the Mallampati score, tonsillar size, and BMI z-score were found to be significant for predicting OSA severity (odds ratio = 4.520, 95% CI: 1.332-15.335, p = 0.015, odds ratio = 9.177, 95% CI: 2.513-33.514, p = 0.001, and odds ratio = 2.820, 95% CI: 1.444-5.508; p = 0.002, respectively). Conclusion: The coexistence of the Mallampati score and BMI z-score significantly increases the presence of OSA in children. Mallampati score, tonsillar size, and BMI z-score are promising parameters for predicting OSA severity.

RESUMO

PURPOSE: It has been suggested that the cause of the balance disorder seen in adolescent idiopathic scoliosis (AIS) originates from the central nervous system. However, the extent of the balance problem and the dysfunction of which part of the central nervous system has not been investigated in detail. This study aimed to correlate the values obtained by balance analysis and cerebellum volume measurement in female individuals with AIS with healthy individuals. METHODS: Cerebellum volume was calculated via the cloud-based software " https://volbrain.upv.es " using brain magnetic resonance images of 27 healthy and 26 individuals with AIS. The duration of stay in the test positions, the movement strategy used during this time and the amount of postural sway were analyzed by using a computer-assisted force platform and compared statistically. RESULTS: Significant differences were found between the AIS and control groups in cerebellum total volume, vermis cerebelli volume (cm3), and trunk oscillation velocity (mm/s) parameters (p < 0.05). Cerebellum and vermis cerebelli volumes were found to be lower and trunk oscillation velocity was found to be greater in patients with AIS. CONCLUSION: Balance problems in patients with AIS are correlated with decreased cerebellum volume and increased trunk oscillation velocity.

RESUMO

Intraoperative electrocorticography (ECoG) is a useful technique to guide resections in epilepsy surgery and is mostly performed under general anesthesia. In this systematic literature review, we seek to investigate the effect of anesthetic agents on the quality and reliability of ECoG for localization of the epileptic focus. We conducted a systematic search using PubMed and EMBASE until January 2019, aiming to review the effects of anesthesia on ECoG yield. Fifty-eight studies were included from 1016 reviewed. There are favorable reports for dexmedetomidine and remifentanil during ECoG recording. There is inadequate, or sometimes conflicting, evidence to support using enflurane, isoflurane, sevoflurane, and propofol. There is evidence to avoid halothane, nitrous oxide, etomidate, ketamine, thiopental, methohexital, midazolam, fentanyl, and alfentanil due to undesired effects. Depth of anesthesia, intraoperative awareness, and surgical outcomes were not consistently evaluated. Available studies provide helpful information about the effect of anesthesia on ECoG to localize the epileptic focus. The proper use of anesthetic agents and careful dose titration, and effective communication between the neurophysiologist and anesthesiologist based on ECoG activity are essential in optimizing recordings. Anesthesia is a crucial variate to consider in the design of studies investigating ECoG and related biomarkers.

RESUMO

BACKGROUND: Agenesis of the corpus callosum (ACC) is the most frequent commissural malformation of the brain. It continues to be an important cause of the pregnancy termination associated with the central nervous system (CNS). OBJECTIVE: The aim of the study is to provide a comprehensive assessment of fetuses with diagnosis of complete ACC, as well as postnatal neurodevelopmental outcomes. METHODS: The data of 75,843 fetuses were screened for evaluation of complete ACC between 2003 and 2017, and a total of 109 cases with complete ACC were included in the study. ACC was considered isolated when no additional anomalies were detected, and ACC was considered complex when additional anomalies were present. RESULTS: The prevalence of complete ACC was 9.4 per 10,000 live births, and the incidence was ranged from 1.8 to 16.6 per 10,000 person-years. Patients with isolated ACC had a significantly higher survival when compared with patients with complex ACC (97.4%, n = 38/39 vs. 68.8%, n = 22/32, P = 0.001).The most important cause of death were congenital heart disease and/or respiratory failure during neonatal period. Developmental and intellectual disabilities were significantly higher in the complex ACC cases (P < 0.001). Postnatal neurodevelopmental outcomes were completely normal in 79.4% of cases with isolated ACC. CONCLUSIONS: Isolated complete ACC is usually associated with a favorable outcome. The most important prognostic factors are the presence or absence of associated congenital anomalies.

RESUMO

OBJECTIVE: To identify causes of the autosomal-recessive malformation, diencephalic-mesencephalic junction dysplasia (DMJD) syndrome. METHODS: Eight families with DMJD were studied by whole-exome or targeted sequencing, with detailed clinical and radiological characterization. Patient-derived induced pluripotent stem cells were derived into neural precursor and endothelial cells to study gene expression. RESULTS: All patients showed biallelic mutations in the nonclustered protocadherin-12 (PCDH12) gene. The characteristic clinical presentation included progressive microcephaly, craniofacial dysmorphism, psychomotor disability, epilepsy, and axial hypotonia with variable appendicular spasticity. Brain imaging showed brainstem malformations and with frequent thinned corpus callosum with punctate brain calcifications, reflecting expression of PCDH12 in neural and endothelial cells. These cells showed lack of PCDH12 expression and impaired neurite outgrowth. INTERPRETATION: DMJD patients have biallelic mutations in PCDH12 and lack of protein expression. These patients present with characteristic microcephaly and abnormalities of white matter tracts. Such pathogenic variants predict a poor outcome as a result of brainstem malformation and evidence of white matter tract defects, and should be added to the phenotypic spectrum associated with PCDH12-related conditions.

RESUMO

BACKGROUND: Disorders of intracellular cobalamin (Cbl) metabolism are classified from A to J according to biochemical phenotype, and genetic and complementation analyses. CblD-deficient patients present with developmental, hematologic, neurologic, and metabolic findings. CLINICAL OBSERVATION: An 11-year-old boy presented with neutropenia, increased mean corpuscular volume, psychomotor retardation, and seizures. His plasma total homocysteine and urinary methylmalonic acid levels were elevated, and a homozygous nonsense mutation [p. R250X (c.748C>T] leading to premature termination of translation was identified in the MMADHC gene, which was compatible with CblD defect. CONCLUSION: In the presence of increased mean corpuscular volume and other hematologic manifestations, such as leukopenia, thrombocytopenia, and megaloblastic anemia, with severe nonspecific or mild neurologic symptoms, Cbl synthesis defects should be considered.

RESUMO

Ischemic stroke is a significant health condition, whose frequency in childhood is increasing day by day. Although many factors are effective in development of the stroke, it has been showed that individuals having risk factors have a genetic predisposition. The aim of the study is to determine whether distinct genetic mutations are risk factors for children with history of ischemic stroke. Our sample data is taken from 58 patients (29 male and 29 female) who applied our hospital between 2012 and 2016 with diagnosis of acute or chronic arterial stroke and from 70 healthy children (32 male and 38 female) with similar particularities in the sense of age and sex, who have not any chronical disease. Blood samples are taken from each child participated in the study to conduct genetic analysis. It has been examined whether a mutation exists in gene locations of CDKN2B-AS1 (Rs2383206), HDAC9 (Rs11984041), NINJ2 (Rs12425791), NAA25 (Rs17696736). Moreover, whether there are significant difference between patient and control group has been investigated. In the genetic analysis of patients and control groups, no significant difference has been found for any of the genes. Mutations in gene locations of CDKN2B-AS1 (Rs2383206), HDAC9 (Rs11984041), NINJ2 (Rs12425791), NAA25 (Rs17696736) are not risk factors for ischemic stroke in childhood. However this study showed us, the patients who inherit CDKN2B-AS1 and HDCA9 gene mutations had poor prognosis. However, this study should be replicated for a wider sample of patient population.

RESUMO

Background Wilson's disease (WD) is a copper metabolism disorder that causes hepatolenticular degeneration. It is important to diagnose WD before central nervous system involvement. Purpose To demonstrate the early susceptibility changes associated with the copper accumulation in the brain of neurologically asymptomatic pediatric patients with WD using quantitative susceptibility mapping (QSM). Material and Methods Twelve patients with neurologically asymptomatic WD (mean age = 13.7 ± 3.3 years) and 14 age-matched controls were prospectively examined using a 1.5-T clinical scanner. Routine magnetic resonance (MR) sequences and a three-dimensional multi-echo spoiled gradient echo (GRE) sequence were used and QSM maps were reproduced. The quantitative susceptibility of corpus striatum, thalamus, substantia nigra, and pons were analyzed with the region of interest analysis on QSM maps. The susceptibility values of two groups were statistically compared using a two-sample t-test. Results Conventional MR images of the patients and control group were similar. However increased magnetic susceptibility in the thalamus, pons and left posterior putamen were observed in the patients compared to the control group ( p < 0.05). Conclusion We observed statistically increased susceptibility values in the brains of neurologically asymptomatic patients with WD although the conventional MR images were normal. This might be compatible with early brain impairment, before neurological symptoms occur.

RESUMO

Background Familial Mediterranean fever (FMF) is an inherited inflammatory disorder characterized by attacks of fever with polyserositis. Objective The purpose of this study was to evaluate pediatric patients with FMF who had central nervous system (CNS) findings. Materials and Methods Our medical records database for 2003 to 2014 was screened retrospectively. In total, 104 patients with FMF were identified, 22 of whom had undergone neurological examination for CNS symptoms. Results Neurological findings included headache in 16 patients (72.7%), epilepsy in 6 patients (27.3%), pseudotumor cerebri in 2 patients (9.1%), tremor in 2 patients (9.1%), and multiple sclerosis in 1 patient (4.5%). The most common MEFV gene mutation was homozygous M694V (40.9%). Conclusions Patients with FMF can present with various CNS manifestations. Further studies that include large populations are needed to elucidate the neurological manifestations of FMF.

RESUMO

Objective Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness, cataplexy, hypnagogic and/or hypnopompic hallucinations, and sleep paralysis. It is one of the most important causes of excessive daytime sleepiness in the pediatric population. The aim of this study is to present the clinical and laboratory findings, and treatment results of pediatric patients with narcolepsy. Materials and Methods We studied five unrelated consecutive children with narcolepsy, focusing on clinical and laboratory features, the therapy and outcome over the 33-month follow-up period. Results The study subjects included two boys and three girls. The mean age at diagnosis was 11.8 ± 3.3 years (range: 8-16 years). Three patients had cataplexy. There were no hypnagogic hallucinations and/or sleep paralysis in any patients. All patients were educated about sleep hygiene, appropriate nutrition, and regular exercise. Three patients were treated with modafinil, while two patients received methylphenidate. Sodium oxybate was added to existing treatment in patients with cataplexy. Cataplexy attacks did not respond well to the treatment in one patient; therefore intravenous immunoglobulin therapy was given. Conclusions Early diagnosis is important to help narcoleptic patients in improving their quality of life. A combination of pharmacological treatment and nondrug interventions can greatly improve children's clinical symptoms.

RESUMO

INTRODUCTION: Syncope is one of the most common clinical problem in children. This disorder is characterized by transient, spontaneously self-terminating loss of consciousness with brief duration and complete recovery. This situation is usually alarming for the families of patients. The mechanism of syncope is transient global brain hypoperfusion to levels below those tolerated by cerebrovascular autoregulation. Syncope can occur with many different etiologies in the pediatric population. CLASSIFICATION: Syncopes are divided into three major categories as neurally mediated syncope, cardiovascular-mediated syncope, and non-cardiovascular syncope. CLINICAL FEATURES: The major challenge in the assessment of children with syncope is that most children are asymptomatic at the time of their presentation, therefore making a careful and detailed history and a comprehensive physical examination essential in all patients. A trigger stimulus is detected in some cases, and this is an important clinical clue for the diagnosis. Cardiac causes of syncope in children are rare but can be life threatening and have the highest risk of morbidity and mortality. Misdiagnosis of epilepsy is common in patients presenting with syncope; therefore, the differential diagnosis between epileptic seizures and syncope is very important. It should be remembered that the evaluation of syncope in children is costly and diagnostic workup has a limited diagnostic yield. CONCLUSION: The aim of this article is to present different types of syncope and to provide new practical clinical approaches to the diagnosis, investigation, and management in the pediatric population.

RESUMO

BACKGROUND: Moyamoya disease is an uncommon, progressive, and occlusive cerebrovascular disorder, predominantly affecting the terminal segment of the internal carotid arteries and its main branches. This occlusion results at the formation of a compensatory collateral arterial network (moyamoya vessels) developing at the base of the brain. The c.14576G>A variant in ring finger protein 213 (RNF213) was recently reported as a susceptibility gene for moyamoya disease. METHODS: We describe two Turkish pediatric siblings with moyamoya disease born to consanguineous, unaffected Turkish parents. RESULTS: The first patient (proband) is a 2-year-old boy who presented with afebrile focal seizures, moderate psychomotor retardation, paresis in the left upper and lower extremity, multiple infarctions of the brain, stenosis of the bilateral internal carotid artery and the middle cerebral artery, and stenosis of the right posterior cerebral artery. The second patient is a 10-year-old girl who is an elder sister of proband. She showed normal psychomotor development, millimetric signal enhancement without diffusion limitation of the brain, and stenosis of the bilateral internal carotid artery. CONCLUSION: We herein report pediatric sibling patients of moyamoya disease who have homozygous wild-type c.14576G>A variant in RNF213, showing different clinical course and disease severity. This is the first report of pediatric siblings with moyamoya disease from Turkey validating the genetic background of most frequent variant in East Asian patients with moyamoya disease.

RESUMO

Tyrosinemia type II is a rare autosomal recessive disorder caused by deficiency of tyrosine aminotransferase (TAT). It may occur with ocular and cutaneous symptoms with or without mental retardation, but epileptic seizure is a rare presentation of this disease. Herein we report the clinical, biochemical and genetic features of a 4-year-old boy who presented with afebrile seizure and photophobia. Genomic DNA was obtained from peripheral blood leukocytes from the whole family. Sequencing analysis was performed using the MiSeq next-generation sequencing platform. Sequencing of TAT indicated two new homozygous mutations p.L312P (c.935T>C) and p.T408M (c.1223C>T) for the proband and his asymptomatic sister. During a 2 year follow-up period, the patient had overall poor compliance with protein-restricted diet, but his asymptomatic sister had good compliance with the diet. Cognitive function of the patient worsened steadily, but his asymptomatic sister maintained normal mental status. Tyrosinemia type II should be considered in the differential diagnosis of children presenting with epileptic seizure and photophobia; furthermore, early diagnosis and protein-restricted regimen are important to reduce the risk of long-term complications of tyrosinemia type II such as mental disability.

RESUMO

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare, life-threatening hypersensitivity drug reaction. Patients present with cutaneous rash, fever, lymphadenopathy, hematologic abnormalities with eosinophilia and atypical lymphocytes, and visceral organ involvement. The prognosis of DRESS syndrome is related to the degree of end-organ damage, and the mortality rate is approximately 10%. CASE REPORT: We report a 9-year-old girl treated with only levetiracetam because of intracranial space occupying mass-related seizures. The patient developed pharyngitis accompanied by exudative membrane, bilateral cervical lymphadenopathy, tender hepatomegaly, skin rash, and fever after 19 days of levetiracetam therapy. Laboratory findings revealed leukocytosis, lymphocytosis with an atypical lymphocytosis, eosinophilia, thrombocytopenia, and elevated serum transaminases. Serologic studies of viruses were negative. The patient was diagnosed with DRESS syndrome and antiepileptic therapy was ceased immediately. The systemic signs and symptoms of the patient were improved after systemic steroid and antihistamine therapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important that emergency physicians be aware of the possibility of DRESS syndrome when attending children that present with clinical viral infections. We would like to emphasize that obtaining a careful and detailed medication history is an essential part of clinical assessment for the diagnosis of DRESS syndrome.

RESUMO

OBJECTIVES: The purpose of this study was to characterize patients who were diagnosed with glucose transporter protein 1 deficiency syndrome (Glut1D), and also to assess the efficacy of ketogenic diet (KD) therapy on seizure control, cognitive functions, and other neurological disorders. PATIENTS AND METHODS: We studied six unrelated patients with the classical phenotype of Glut1D, focusing on clinical and laboratory features, the KD therapy and outcome over the 25-month follow-up period. RESULTS: Five patients became seizure-free with the onset of ketosis, and anticonvulsants were discontinued. Other neurological features such as ataxia, spasticity, and dystonia showed a less striking improvement than seizure control. There was no significant change in the intelligence quotient (IQ) level or microcephaly. In all patients, alertness, concentration, motivation, and activity resulted in a moderate improvement of variable degree. The early-onset adverse effects of KD were observed in five patients. The KD regimen failed in one patient, therefore, his diet was changed with an alternative to KD. CONCLUSIONS: Treatment with KD resulted in a marked improvement in seizures and cognitive functions but its effect appeared to be less striking on the other neurological disorders of the patients. When the classic KD is not tolerated, an alternative to KD may be helpful.

RESUMO

Tangier disease (TD) is a rare, autosomal recessive inherited disorder caused by a mutation in the adenosine triphosphate-binding cassette transporter 1 (ABCA1) gene, which results in a decrease in plasma high-density lipoprotein (HDL) levels. Peripheral neuropathy can be seen in approximately 50% of patients with TD, which usually occurs after the age of 15 years, and is characterized by relapsing-remitting mono- or polyneuropathy or syringomyelia-like neuropathy. Herein, we report a 16-year-old female patient who was initially diagnosed with peripheral neuropathy at the age of 13 years. Whole exome sequencing was performed, and a nonsense mutation (p.Arg1817X) in ABCA1 was identified. The patient was investigated for systemic findings of TD after the genetic diagnosis was made, and low (< 5 mg/dL) levels of HDL cholesterol were detected by lipid electrophoresis. Other family members were reexamined after the diagnosis of the proband, and asymptomatic sister of the proband was diagnosed with TD. We would like to emphasize that TD should be considered in the differential diagnosis of pediatric patients presenting with peripheral neuropathy; furthermore detection of HDL levels by lipid electrophoresis is a simple but indicative diagnostic test.

RESUMO

PURPOSE: The aim of this study is to investigate the spectrum of underlying disease in children with torticollis. METHODS: We investigated the spectrum of underlying disease and to evaluate the clinical features of the children presented with torticollis in the last 2 years. RESULTS: Of the 20 children (13 girls and 7 boys with the mean age of 8 years, ranging 2 months-12 years), eight of them have craniospinal pathologies (cerebellar tumors in three, exophytic brain stem glioma, eosinophilic granuloma of C2 vertebra, neuroenteric cyst of the spinal cord, Chiari type 3 malformation, arachnoid cysts causing brainstem compression, and cerebellar empyema), followed by osseous origin in five (congenital vertebral anomalies including hemivertebrae, blocked vertebra, and segmentation anomalies), two muscular torticollis (soft tissue inflammation due to subclavian artery catheterization, myositis ossificans with sternocleidomastoid muscle atrophy), and ocular (congenital cataract and microphthalmia), Sandifer syndrome, paroxysmal torticollis, retropharyngeal abscess each in one patients were detected. Ten patients underwent surgery; two patients received medical therapy for reflux and benign paroxysmal torticollis; and one patient with torticollis due to muscle spasm and soft tissue inflammation was treated with physiotherapy. CONCLUSIONS: Various underlying disorders from relatively benign to life-threatening conditions may present with torticollis. The first step should be always a careful and complete physical examination, which must include all systems. Imaging must be performed for ruling out underlying life-threatening diseases in children with torticollis, particularly, if acquired neurological symptoms exist. Besides craniospinal tumors, ophthalmological problems and central nervous system infections should also be kept in mind. Moreover, early diagnosis of these disorders will reduce mortality and morbidity. Therefore, alertness of clinicians in pediatric and pediatric neurosurgery practice must be increased about this alert symptom.

RESUMO

PURPOSE: Vitamin K deficiency bleeding is one of the most common causes of acquired hemostatic disorder in early infancy. Although vitamin K is practiced routinely after every birth in Turkey, children with type of vitamin K deficiency bleedings (L-VKDB) can be encountered. We aimed to evaluate the clinical features of the children with L-VKDB reported from Turkey. METHODS: Between 1995 and 2013, 48 studies reporting 534 children with L-VKDB were evaluated in this study. RESULTS: Of the 534 reported children (178 girls, 356 boys), 486 (91 %) were extremely breastfed. The most common bleeding sites were intracranial hemorrhage, gastrointestinal, and umbilical in 414 (77.4 %), 33 (6.2 %), and 33 (6.2 %) children, respectively, and 35 (6.6 %) children had been diagnosed incidentally without any bleeding. The etiology of 399 (74.7 %) children were classified as idiopathic, whereas 135 (25.3 %) were secondary. Intramuscular vitamin K was administered in 248 (46.4 %), not administered in 228 (42.7 %), and the administration of vitamin K were not determined in 58 (10.9 %) children. The outcomes of Turkish cohort showed that 111 (20.8) children died, 257 (48.1 %) cases developed neurologic deficit (mainly epilepsy and psychomotor retardation), and only 166 (31.1 %) patients recovered without squeal. CONCLUSIONS: The compliance of prophylactic measures in Turkey does not seem to be satisfactory. As a further measure of tomorrow, we vigorously emphasize that a national surveillance program may be initiated. An additional intramuscular dose or oral supplementation of vitamin K especially for exclusively breast-fed infants may reduce this catastrophic problem in our country.

RESUMO

INTRODUCTION: Torticollis can be congenital or may be acquired in childhood. Acquired torticollis occurs because of another problem and usually presents in previously normal children. The causes of acquired torticollis include ligamentous, muscular, osseous, ocular, psychiatric, and neurologic disorders. OBJECTIVE: We performed this study to evaluate the underlying causes of torticollis in childhood. MATERIAL AND METHODS: Ten children presented with complaints of torticollis between April 2007 and April 2012 were enrolled in this study. The additional findings of physical examination included neck pain, twisted neck, walking disorder, imbalance, and vomiting The identified etiologies of the enrolled children was acute disseminated encephalomyelitis in a 2.5-year-old boy, posterior fossa tumor in a 10-month-old boy, spontaneous spinal epidural hematoma in a 5-year-old hemophiliac boy, cervical osteoblastoma in a 3-year-old boy, arachnoid cyst located at posterior fossa in a 16-month-old boy, aneurysm of the anterior communicating artery in a 6-year-old girl, pontine glioma in a 10-year-old girl, and a psychogenic torticollis in a 7-year-old boy were presented. CONCLUSION: There is a wide differential diagnosis for a patient with torticollis, not just neurological in etiology which should be considered in any patient with acquired torticollis. Moreover, early diagnosis of etiological disease will reduce mortality and morbidity. Therefore, clinicians managing children with torticollis must be vigilant about underlying neurological complications.
