Abstract
Dyke-Davidoff-Masson syndrome is a rare neurological condition characterized by intractable seizures, cerebral hemiatrophy with contralateral hemiparesis. Our patient, a 38-year-old female, presented following a left focal seizure with secondary generalization. She had a history of epilepsy, associated with left-sided hemiparesis, beginning at the age of 7. Physical examination showed increased left-sided tone and brisk reflexes, with an extensor plantar reflex on the left. The MRI brain showed features suggestive of Dyke-Davidoff-Masson syndrome: right-sided cortical atrophy, calvarial thickening and dilated frontal sinus. Additional MRI findings were of right cerebral peduncle atrophy and left cerebellar atrophy. This case report intends to emphasize the importance of Dyke-Davidoff-Masson syndrome as an unusual cause of seizures in an adult complicated by poor social determinants of health, leading to its delayed diagnosis.

Abstract
Dyke-Davidoff-Masson syndrome (DDMS) is a rare neurological anomaly encompassing clinical features of seizures, contralateral hemiparesis, facial asymmetry, and intellectual dysfunction. Radiographic findings include cerebral hemiatrophy and ipsilateral calvarial thickening. We encountered an 11-year-old male who presented with new-onset seizures and a 4-year history of weakness in the abduction of his right arm, previously being managed as Erb's palsy. Brain MRI revealed atrophy of the left cerebral hemisphere with ipsilateral dilated ventricle and osseous thickening, consistent with the congenital form of DDMS. We present this case of an atypical presentation of DDMS.

Abstract
INTRODUCTION Dyke-Davidoff-Masson Syndrome (DDMS) is a clinical syndrome that causes different clinical symptoms and is defined by volume decrement in one cerebral hemisphere. In this study, we aimed to evaluate the involvement of the normal-appearing contralateral hemisphere in 16 pediatric patients with DDMS using diffusion-weighted imaging (DWI). MATERIALS AND METHODS Brain MRIs were retrospectively reviewed between January 2014 and January 2023. Sixteen pediatric patients radiologically compatible with DDMS were included in the study. Sixteen children who had undergone brain MRI, most commonly for headaches and whose MRI findings had been completely normal, were included as the control group. Apparent diffusion coefficient (ADC) values of the deep gray and white matter of the normal-appearing hemisphere in the patient group were calculated and compared with that of the control group. RESULTS The ADC values of the gray and white matters of the patient and control groups were not statistically different. However, in the patient group, the ADC values of the gray and white matters in males were remarkably lower than in females (p = 0.038, p = 0.037, respectively). CONCLUSION The difference in the ADC values of the contralateral hemisphere between females and males in the patient group suggests that the normal-appearing hemisphere may have been affected by DDMS. Although, the exact mechanism of this effect is not known. Therefore, in patients with DDMS, contralateral hemisphere involvement in cerebral hemiatrophy and hemispherectomy should be evaluated clinically and radiologically.

Abstract
INTRODUCTION Dyke-Davidoff-Masson syndrome (DDMS), or cerebral hemiatrophy, was first described in 1933. It is characterised by cerebral injury that causes hypoplasia in one of the cerebral hemispheres. The disease has different clinical degrees and two aetiologies: congenital and acquired. Radiological findings depend on the degree of injury and the patient's age at the time. OBJECTIVE To provide information on the main clinical and radiological characteristics of this disease. METHODS A systematic review of the PubMed, MEDLINE, and LILACS databases was conducted using only one keyword. Dyke-Davidoff-Masson syndrome. A total of 223 studies were identified, and the results are presented in tables and graphics. RESULTS The mean age of the patients was 19.44 (0-83 years), and the majority were male (55.32%). The most common types of epileptic seizures were generalised tonic-clonic seizures (31 cases), focal impaired awareness seizures (20 cases), focal motor seizures (13 cases), focal to bilateral tonic-clonic seizures (nine cases), and focal myoclonic seizures (one case). The main features of the disease were rapid deep tendon reflexes and extensor cutaneous-plantar tendon reflexes (30 cases - 16%), contralateral hemiparesis or hemiplegia (132 cases - 70%), gait alterations (16 cases - 9%), facial paralysis (nine cases - 5%), facial asymmetry (58 cases - 31%), limb asymmetry (20 cases - 11%), delayed developmental milestones (39 cases - 21%), intellectual disability (87 cases - 46%), and language/speech disorders (29 cases - 15%). Left hemisphere atrophy was the most prevalent. CONCLUSION DDMS is a rare syndrome, and several questions regarding this disease remain unanswered. This systematic review aims to elucidate the most common clinical and radiological aspects of the disease and emphasises the need for further investigation.

Abstract
Introduction Perinatal stroke (PS) is a focal vascular brain injury and the leading cause of hemiparetic cerebral palsy. Motor impairments last a lifetime but treatments are limited. Transcranial direct-current stimulation (tDCS) may enhance motor learning in adults but tDCS effects on motor learning are less studied in children. Imaging-based simulations of tDCS-induced electric fields (EF) suggest differences in the developing brain compared to adults but have not been applied to common pediatric disease states. We created estimates of tDCS-induced EF strength using five tDCS montages targeting the motor system in children with PS [arterial ischemic stroke (AIS) or periventricular infarction (PVI)] and typically developing controls (TDC) aged 6-19 years to explore associates between simulation values and underlying anatomy. Methods Simulations were performed using SimNIBS https://simnibs.github.io/simnibs/build/html/index.html using T1, T2, and diffusion-weighted images. After tissue segmentation and tetrahedral mesh generation, tDCS-induced EF was estimated based on the finite element model (FEM). Five 1mA tDCS montages targeting motor function in the paretic (non-dominant) hand were simulated. Estimates of peak EF strength, EF angle, field focality, and mean EF in motor cortex (M1) were extracted for each montage and compared between groups. Results Simulations for eighty-three children were successfully completed (21 AIS, 30 PVI, 32 TDC). Conventional tDCS montages utilizing anodes over lesioned cortex had higher peak EF strength values for the AIS group compared to TDC. These montages showed lower mean EF strength within target M1 regions suggesting that peaks were not necessarily localized to motor network-related targets. EF angle was lower for TDC compared to PS groups for a subset of montages. Montages using anodes over lesioned cortex were more sensitive to variations in underlying anatomy (lesion and tissue volumes) than those using cathodes over non-lesioned cortex. Discussion Individualized patient-centered tDCS EF simulations are prudent for clinical trial planning and may provide insight into the efficacy of tDCS interventions in children with PS.

Abstract
The Duke-Davidoff-Masson syndrome (DDMS) is a rare neurological condition with unknown prevalence, globally. To date, <100 cases have been reported worldwide. We report the case of an 18-year-old patient admitted for status epilepticus seizure, and who presented a right hemiparesis, body asymmetry, joints ankylosis, and mental retardation. Brain CT-scan revealed left hemisphere atrophy, skull bone thickening, and hyperpneumatization of the frontal sinuses; all consistent with DDMS. Seizures improved remarkably on Levetiracetam and Valproate. This is the first report of an unusual DDMS in Mali, and the diagnosis delay highlights the challenges for the management of these diseases in resource-limited settings.

Abstract
Symmetry of the face is one of the most important features for the perception of attractiveness. Asymmetry of the face means that the right and left sides of the face are not identical. Subclinical facial asymmetry is very common in the general population. Most people have some slight facial asymmetry, and this is the normal biological situation in humans. Abnormalities from soft tissue, dental, and skeletal elements lead to facial asymmetry. Asymmetry has many causal factors, and its aetiology includes both congenital and acquired conditions. Neurological facial asymmetry is scarcely addressed in the dental literature. In this narrative review, we focus on the most common neurological causes of facial asymmetry. From a neurological point of view, facial asymmetry can result from disturbances of the cranial nerves, developmental disorders, or myopathies. In the broad range of differential diagnostics of facial asymmetry, neurological abnormalities should be taken into consideration. The treatment must be related to the underlying cause. Complete knowledge of the aetiological factors and the character of the asymmetry plays a crucial role in formulating a treatment plan.

Abstract
Background DDMS is a rare disease diagnosed by clinical and radiological characteristics. But the complexity of radiological and clinical manifestations of DDMS has become a challenge diagnostically. To date, the reported cases with DDMS had highly varied clinical manifestations including seizures, contralateral hemiplegia/hemiparesis, facial asymmetry, mental retardation, etc. In addition to typical clinical findings, some new characteristics have been recently added to the spectrum of DDMS. However, few cases have been reported to be associated with neuropsychiatric symptoms according to the literature. This study aimed to investigate the neuropsychiatric manifestations associated with Dyke-Davidoff-Masson syndrome (DDMS) and related imaging findings. Methods This study included 7 patients diagnosed with DDMS between 2014 and 2020. The clinical characteristics, neuropsychiatric manifestations, and radiological results were retrospectively evaluated. Results Seven patients (five males and two females) with a mean age of 28.0 ± 9.73 (range 15.0–41.0) years were included. Five patients were admitted to the psychiatric unit due to psychological and behavioral disorders. Two patients were referred to the neurology unit mainly due to epilepsy. Six patients had epileptic seizures, 4 had hemiplegia, 3 had mental retardation, 2 patients had external ear deformities, and 2 had facial asymmetry. Neuropsychiatric symptoms were presented in 6 (85.7 %) cases. Cases 2–6 developed affective disorders. Deficits in verbal communication, impairment of social interaction, lack of insight, adulia and hypobulia appeared in cases 1–4. Schizophrenia with apathy, and epileptic schizoid psychosis were observed in cases 4 and 5 respectively. Case 6 had behavioral disorders, hyperactivity, tic disorder, mental retardation, anxiety, catatonic symptoms and suicidal tendency. Case 7 had seizures and mental retardation, and no psychiatric symptoms were presented. Radiological examinations showed unilateral cerebral atrophy, enlarged lateral ventricles, and various compensatory hypertrophy of the skull in all cases. The midline structure has shifted to the affected side in 5(71.4 %) cases. Atrophy of the basal ganglia or brain stem was observed in 4(57.1 %) cases. Conclusions The hallmark imaging manifestations of DDMS facilitated the diagnosis in most cases. This study illustrated that a variety of psychoneurotic disorders and ear abnormalities were correlated with DDMS.

Abstract
Birds and their ornithodiran ancestors are unique among vertebrates in exhibiting air-filled sinuses in their postcranial bones, a phenomenon called postcranial skeletal pneumaticity. The factors that account for serial and interspecific variation in postcranial skeletal pneumaticity are poorly understood, although body size, ecology, and bone biomechanics have all been implicated as influencing the extent to which pneumatizing epithelia invade the skeleton and induce bone resorption. Here, I use high-resolution computed-tomography to holistically quantify vertebral pneumaticity in members of the neognath family Ciconiidae (storks), with pneumaticity measured as the relative volume of internal air space. These data are used to describe serial variation in extent of pneumaticity and to assess whether and how pneumaticity varies with the size and shape of a vertebra. Pneumaticity increases dramatically from the middle of the neck onwards, contrary to previous predictions that cervical pneumaticity should decrease toward the thorax to maintain structural integrity as the mass and bending moments of the neck increase. Although the largest vertebrae sampled are also the most pneumatic, vertebral size cannot on its own account for serial or interspecific variation in extent of pneumaticity. Vertebral shape, as quantified by three-dimensional geometric morphometrics, is found to be significantly correlated with extent of pneumaticity, with elongate vertebrae being less pneumatic than craniocaudally short and dorsoventrally tall vertebrae. Considered together, the results of this study are consistent with the hypothesis that shape- and position-specific biomechanics influence the amount of bone loss that can be safely tolerated. These results have potentially important implications for the evolution of vertebral morphology in birds and their extinct relatives.

Abstract
Dyke-Davidoff-Masson syndrome (DDMS) is a rare neurological disorder that results from brain injury in intrauterine or early years of life. Prominent cortical sulci, dilated lateral ventricles, cerebral hemiatrophy, hyperpneumatization of the frontal sinus, and compensatory hypertrophy of the skull are the characteristic findings. We describe a male patient who presented with generalized tonic-clonic seizure and left-sided body weakness and neuroimaging findings of cerebral hemiatrophy, dilatation of right lateral ventricle, right frontal sinus hyperpneumatization, and asymmetric calvarial thickening. Knowledge of its features on imaging enables timely and accurate diagnosis, allowing appropriate management.

Abstract
Introduction The loss of parenchymal brain volume per normative age comparison is a distinctive feature of brain atrophy. While the condition is the most prevalent to elderly, it has also been observed in pediatric ages. Various causes such as trauma, infection, and malnutrition have been reported to trigger the loss of brain tissues volume. Despite this literature based knowledge of risk factors, the magnitude of brain atrophy in pediatric age group is scantly addressed in most developing countries including Tanzania. The current study aims to understand the magnitude of brain atrophy in children residing in Northern Zone, Tanzania. Methods A cross-sectional hospital survey was performed in which 455 children who were presented with various brain pathologies from the year 2013 to 2019 and whose brains examined by Computerized tomography (CT)-Scanners were recruited in the study. The brain statuses were examined using three linear radiological methods including the measure of sulcal-width, Evans index, and lateral ventricular body width. Results Results showed a significant number of atrophied brains among children in Northern Tanzania and that the condition was observed to have a 1:1 male to female ratio. The prevalence of pediatric brain atrophy was found to be 16.04%. Conclusion The cortical subtype of brain atrophy presented as the most prevalent type of brain volume loss. The findings of this study suggest existence of considerable trends of brain atrophy in children which need special attention and mitigation plans.

Abstract
Dyke-Davidoff-Masson syndrome (DDMS) was first described in 1933 as a clinical condition characterized by hemiatrophy, hyperpneumatization of paranasal sinuses, contralateral hemiparesis, facial asymmetry, seizures, and mental retardation.1 DDMS can be of 2 types: congenital and acquired. The congenital type can be caused by various conditions experienced during fetal or early childhood development, including ischemia, infarction, trauma, infections, and hemorrhage. The acquired type is mostly associated with hemorrhage, trauma, and infections experienced after 1 month of age. DDMS can manifest alone or can be accompanied by crossed cerebellar atrophy (CCA) which is a newly discovered radiological marker characterized by prominent cortical sulci and loss of cerebellar parenchyma. The congenital type of DDMS is known to be accompanied by ipsilateral cerebellar atrophy and the acquired type is known to be accompanied by contralateral cerebellar atrophy.2,3 Supratentorial events may lead to destruction in the cortico-ponto-cerebellar pathways, mostly in the contralateral side of the body (80%) due to decussation.4 In this report, we present 2 cases of DDMS accompanied by CCA to emphasize the possibility that the DDMS cases with severe intrauterine hemorrhage can be accompanied by contralateral CCA and migratory abnormalities rather than ipsilateral CCA and clinical survey.

Abstract
Background Dyke-Davidoff-Masson syndrome is a rare condition of unknown frequency resulting from brain injury due to a multitude of causes; especially in early life. Characteristics include cerebral hemiatrophy/hypoplasia, contralateral hemiparesis, seizures, and compensatory osseous hypertrophy. Case presentation We present a case of a 13-year-old girl who initially presented with headaches, followed by episodic complex-partial seizures; which was controlled via medication. She also had right sided hemiparesis. Computed tomography (CT) showed evidence of left parieto-temporal infarct with cerebral atrophy. Complementary magnetic resonance imaging (MRI) did not reveal additional information. Workup for young stroke was negative. Upon further evaluation by Neuroradiology, features suggesting Dyke-Davidoff-Masson syndrome were confirmed. Patient has been under Neurology follow up since. Conclusions Due to its rarity, Dyke-Davidoff-Masson syndrome may easily be missed by the majority of treating clinicians. Knowledge of its features on imaging enables timely and accurate diagnosis – allowing appropriate management.

Abstract
Radiological findings of Dyke-Davidoff-Masson syndrome (DDMS) in patients with different etiologies are presented in our study. The study included 12 patients (seven females, five males) for whom radiological examinations were requested due to reasons such as epilepsy, mental retardation, and/or hemiplegia. CT was performed in 12, MRI in 6, MRA in 1, and DSA in 1 patient. Following imaging findings were evaluated: cerebral and cerebellar involvement (laterality, encephalomalacia), affected territories, ventricular enlargement, sulcal enlargement, calvarial thickening, and paranasal sinus enlargement hyperaeration. Age range of the patients was 5-62 (mean 34.1 ± 21.7). Left hemicrania was affected in eight patients, right hemicrania in four. Ipsilateral calvarial thickening and lateral ventricular dilatation were observed in all patients. 11 patients had ipsilateral frontal sinus hyperaeration, sulcal enlargement and encephalomalacia. Wallerian degeneration of the mesencephalon and middle fossa hypoplasia was seen in ten patients, mastoid hyperaeration, third ventricular enlargement and thalamic involvement in nine, and corpus callosum, basal ganglion injury, and sphenoid sinus hyperaeration in eight. MCA, ACA, and PCA territories were involved in six patients. Only MCA territory involvement was seen in four patients. Cerebellar atrophy was contralateral in two patients. Symmetric bilateral atrophy was observed in one patient. DDMS can be encountered with different radiological findings based on cerebral damage formation process and the extent of damage. Patients may have different levels of cerebral hemiatrophy, ipsilateral carvarial thickening, and lateral ventricular dilatation.

Abstract
Dyke-Davidoff-Masson syndrome (DDMS) is characterized by cerebral hemiatrophy, seizure, contralateral hemiplegia/hemiparesis, and mental retardation. In this study, clinical and radiological investigations of seven patients who were diagnosed with DDMS as adult age were evaluated and discussed. Seven patients (four male, three female) were included. The mean age ± SD of the patients was 46 ± 21 years. Clinical presentation of six patients was epileptic seizure. One patient was presented with head trauma due to a fall. Two patients had complex partial seizures, three patients had generalized tonic-clonic seizures (GTC), and one had GTC and myoclonic seizure. Mental retardation was in five patients. A congenital cause was detected in one patient in the etiologic investigation and acquired causes in two patients. In four patients, the etiology was not identified. We observed left-hemisphere involvement in four patients and right-hemisphere involvement in three patients. Brain imaging was performed by CT only in four patients and by MRI only in three patients. All patients were diagnosed with DDMS at adulthood. Atrophy in basal ganglia was detected in five patients, and atrophy in brain stem in four patients. Calvarial thickening was observed in four patients. Three patients had hyperpneumatization in mastoid cells. Sinus hyperpneumatization, including the paranasal and frontal sinuses, was seen in six patients. DDMS can also be diagnosed in adulthood symptomatically (mild-severe) or asymptomatically in adulthood. As a result, DDMS is a syndrome with wide clinical and radiological spectra that can be variably symptomatic at different stages of life.

Abstract
Dyke-Davidoff-Masson syndrome (DDMS) is a rare disorder characterized by recurrent seizures, facial asymmetry, contralateral hemiplegia, radiologic features of cerebral hemiatrophy, and ipsilateral compensatory hypertrophy of the skull bone and sinuses. We describe three cases of children with DDMS, who initially presented with refractory seizure to the pediatric department of North Bengal Medical College and Hospital, India. In each case, the clinical features noted along with computed tomography or magnetic resonance imaging helped confirm the diagnosis of DDMS. DDMS should be considered as a differential diagnosis of refractory seizures in children. We seek to emphasize the importance of thorough clinical and neuroimaging workup of seizure disorder in children for the proper management of the condition.

Abstract
Dyke-Davidoff-Masson syndrome (DDMS) refers to atrophy or hypoplasia of one cerebral hemisphere, due to an insult to the developing brain in fetal or early childhood period. Age of presentation depends on the time of neurologic insult, and characteristic changes may be seen only in adolescence. Male gender and left hemisphere are more frequently involved. A 17-year-old female adolescent with a history of recurrent refractory seizures, hemiplegia and mental retardation reported to Department of Radiology for computed tomography (CT) assessment of brain. On examination, she had facial asymmetry, delayed milestones, and spastic hemiplegia. The CT brain showed right cortical atrophy with ventricular dilatation, prominent sulci, and shifting of falx to the right side. Bone window image showed asymmetry in skull vault thickness, the width of diploic space, the size of paranasal air sinuses and inclination of the petrous ridge between the affected and normal sides. As the above case deviates from the usual presentation of male left sided DDMS, hence the report.

Abstract
CASE REPORT A 3.5-year-old spayed female Domestic Shorthair cat was evaluated for new onset seizures and lateralising signs indicative of a lesion in the right prosencephalon. Magnetic resonance imaging and computed tomography of the head revealed hypoplasia of the right cerebral hemisphere and changes in the overlying cranium, including hyperostosis and expansion of the diploic space, resulting in an increased pneumatisation of the rostral bones of the cranium. A congenital injury to the cerebral hemisphere and secondary changes of the cranium in response to the decreased brain parenchyma was presumed. Similar changes have been previously recognised in human patients with unilateral anomalies of the cerebral hemispheres, termed Dyke-Davidoff-Masson syndrome (DDMS). CONCLUSION The case presented is the first clinical and imaging description of a cat with a syndrome that closely resembles DDMS in humans. The description of the syndrome allows recognition of an additional differential for seizures in a young patient and informs the clinician of the imaging characteristics of the cranium seen with early loss of brain parenchyma.

Abstract
We present a case of hemihypoplasia of the striatum with ipsilateral cerebral hemispheric atrophy. The head of the caudate nucleus and putamen were hypoplastic, and gray matter cell bridges between them located in the anterior limb of the internal capsule were sparse. Cerebral atrophy was accompanied by ipsilateral mesial temporal sclerosis without thalamic atrophy. The anterior limb of the internal capsule showed no signal abnormalities or volume loss. These imaging findings and the hyperintensity at the fundus striati suggest an early embryonic insult of lateral striatal elevation.

Abstract
PURPOSE Cerebral hemiatrophy is a common childhood disease. It clinically manifests with seizures, hemiparesis and mental retardation. MATERIALS AND METHODS In this prospective study, previously untreated patients with seizures and cerebral hemiatrophy were recruited. Cerebral hemiatrophy was diagnosed on the basis of hemispheric ratio. Patients with acquired hemiconvulsion, hemiplegia, and epilepsy (HHE) syndrome were included in group A. Group B included patients with congenital HHE syndrome. Patients were followed up for 6 months for seizure recurrence. RESULTS Out of 42 patients 26 were in group A and 16 were in group B. After 6 months, there was significant reduction in seizure frequency (P < 0.0001) in both the groups. At least 50% reduction in seizure frequency was noted in all the patients. Complete seizure freedom was observed in 15 (35.7%) patients. Seizure recurrences were significantly higher (P = 0.008) in group A. On univariate analysis, predictors of seizure recurrences were history of febrile seizures (P = 0.013), hippocampal sclerosis (P = 0.001), thalamic atrophy (P = 0.001), basal ganglia atrophy (P = 0.001), cerebellar atrophy (P = 0.01), ventricular dilatation (P = 0.001), epileptiform discharges at presentation (P = 0.023), complex partial seizures (P = 0.006) and status epilepticus (P = 0.02). On multivariate analysis, hemispheric ratio was the only significant factor for seizure recurrence. CONCLUSION Patients with congenital hemiatrophy had better seizure control than that in patients with HHE syndrome.

Abstract
A diagnosis of central hypothyroidism (CH) can be missed easily or delayed without a high index of suspicion due to normal or slightly altered thyroid stimulating hormone (TSH) levels during the initial screening test for thyroid dysfunction. A correct diagnosis of CH is very important for safely treating patients. Specifically, doctors must ensure a proper evaluation of combined adrenal insufficiency to prevent a fatal adrenal crisis. Here we report a case of CH combined with secondary adrenal insufficiency in a 42-year-old woman with Dyke-Davidoff-Masson syndrome, which is a rare neurological disease.

Abstract
Prenatal ultrasonographic detection of unilateral cerebral ventriculomegaly arises suspicion of pathological condition related to cerebrospinal fluid flow obstruction or cerebral parenchimal pathology. Dyke-Davidoff-Masson syndrome is a rare condition characterized by cerebral hemiatrophy, calvarial thickening, skull and facial asymmetry, contralateral hemiparesis, cognitive impairment and seizures. Congenital and acquired types are recognized and have been described, mainly in late childhood, adolescence and adult ages. We describe a female infant with prenatal diagnosis of unilateral left ventriculomegaly in which early brain MRI and contrast enhanced-MRI angiography, showed cerebral left hemiatrophy associated with reduced caliber of the left middle cerebral artery revealing the characteristic findings of the Dyke-Davidoff-Masson syndrome. Prenatal imaging, cerebral vascular anomaly responsible for the cerebral hemiatrophy and the early clinical evolution have never been described before in such a young child and complete the acquired clinical descriptions in older children. Differential diagnosis, genetic investigations, neurophysiologic assessments, short term clinical and developmental follow up are described. Dyke-Davidoff-Masson syndrome must be ruled out in differential diagnosis of fetal unilateral ventriculomegaly. Early clinical assessment, differential diagnosis and cerebral imaging including cerebral MRI angiography allow the clinicians to diagnose also in early infancy this rare condition.

Abstract
Childhood cerebral hemiatrophy is an uncommon clinical entity. Its aetiologies are diverse but can generally be grouped into congenital and acquired. The congenital type is intrauterine in origin while the acquired type occurs early in life, usually before two year of life. When childhood cerebral hemiatrophy occurs, it evokes a spectrum of compensatory calvarial sequlae. These include ipsilateral calvarial thickening, diploe widening, hyper-pneumatization of paranasal sinues/ mastoids, elevation of petrous bone and small middle cranial fossa. MRI is very effective in high lightening brain atrophy, associated parenchymal changes and even the above enumerated skull changes. Our two case reports of left hemi-cerebral atrophy in male Cameroonian children seen in our MRI practice aptly demonstrated some of the aforementioned radiological features of childhood cerebral hemiatrophy noted in literature review.

Abstract
PURPOSE Unverricht-Lundborg disease (EPM1) is a rare type of inherited progressive myoclonic epilepsy resulting from mutations in the cystatin B gene, CSTB, which encodes a cysteine cathepsin inhibitor. Cystatin B, cathepsin K, and altered osteoclast bone resorption activity are interconnected in vitro. This study evaluated the skeletal characteristics of patients with EPM1. METHODS Sixty-six genetically verified EPM1 patients and 50 healthy controls underwent head MRI. Skull dimensions and regional calvarial thickness was measured perpendicular to each calvarial bone from T1-weighted 3-dimensional images using multiple planar reconstruction tools. All clinical X-ray files of EPM1 patients were collected and reviewed by an experienced radiologist. A total of 337 X-ray studies were analyzed, and non-traumatic structural anomalies, dysplasias and deformities were registered. RESULTS EPM1 patients exhibited significant thickening in all measured cranial bones compared to healthy controls. The mean skull thickness was 10.0±2.0mm in EPM1 patients and 7.6±1.2mm in healthy controls (p<0.001). The difference was evident in all age groups and was not explained by former phenytoin use. Observed abnormalities in other skeletal structures in EPM1 patients included thoracic scoliosis (35% of EPM1 patients) and lumbar spine scoliosis (35%), large paranasal sinuses (27%), accessory ossicles of the foot, and arachnodactyly (18%). CONCLUSIONS Skull thickening and an increased prevalence of abnormal findings in skeletal radiographs of patients with EPM1 suggest that this condition is connected to defective cystatin B function. These findings further emphasize the role of cystatin B in bone metabolism in humans.

Abstract
Authors describe the case of a 16-year-old girl who presented with fever, tonic-clonic seizures, unequal arm blood pressures and pulselessness in the left upper limb. On examination, there was a systolic bruit over umbilical region, a pansystolic murmur of mitral regurgitation was found. Neurological examination was normal except for an asymmetry in brain hemicircumference one side compared with the other. She has borderline intelligence (IQ 70) according to Wechsler Adult Performance Intelligence Scale. Magnetic resonance imaging (MRI) of brain revealed atrophic of left cerebral hemisphere with mildly ventricular dilatation, prominent paranasal and mastoid air cells, suggestive of Dyke-Davidoff-Masson syndrome (DDMS). Conventional angiography showed narrowed left internal carotid artery. There was also stenosed brachial artery, absent left renal artery with narrowed infrarenal abdominal aorta. The patient was put on antihypertensive drugs. We hypothesise that Takayasu arteritis and related vascular occlusion is the cause of her acquired cerebral changes.

Abstract
The purpose of this study was to retrospectively evaluate the cognitive and electroclinical characteristics of right cerebral hemiatrophy (Dyke-Davidoff-Masson syndrome [DDMS]). Cognitive assessments with a particular emphasis on visuospatial functions, electroclinical features, and neuroimaging characteristics were analyzed for five patients with a clinically and neuroradiologically confirmed diagnosis of right-sided DDMS. Intelligence tests revealed mental retardation in all but one. Neuropsychological assessments demonstrated consistent impairments in tasks that have a spatial component (spatial processing and orientation discrimination), whereas attention, executive functions and verbal memory domains were variably impaired. Electroclinically, the main seizure types were simple partial motor, complex partial, and secondarily generalized seizures. Interictal EEG delineated lower amplitudes and slow background activity in the affected hemisphere. Overall, the cognitive performance of patients with DDMS encompasses a broad spectrum of impairments affecting multiple domains. Our findings support the concept that dorsal visual pathways responsible for spatial processing may be lateralized to the right hemisphere.

Abstract
Dyke-Davidoff-Masson syndrome is a disorder involving hemiatrophy or hypoplasia of 1 cerebral hemisphere secondary to an insult in the developing brain. Often this will manifest with seizures, hemiparesis, mental retardation, and facial changes. Associated with this pathology are the radiologically evident changes, such as thickening of the calvarium, hyperpneumatization of the sinuses, and dilation of the ipsilateral lateral ventricle among others. The following is a case presentation of an 18-year-old female emigrating from Ghana who presented to the emergency department with complaints of seizures diagnosed as being caused by cerebral malaria at 13 years of age. We hypothesize that the cerebral malaria and related vascular occlusion are the causes of her acquired cerebral changes. Included are computed tomography images.

Abstract
The Dyke-Davidoff-Masson syndrome is characterized by various symptoms related to hemiatrophy of the cerebrum and hypertrophy of the ipsilateral calvarium and paranasal sinuses. Clinical findings include hemiparesis or hemiplegia, seizures and/or mental retardation. The present report discusses the very unusual case of a late-diagnosed Dyke-Davidoff-Masson syndrome in a 75-year-old body donor who had suffered a left-sided stroke associated with the internal carotid artery in the course of tonsillitis at the age of 5.
