Abstract
Abusive head trauma (AHT) refers to a well-recognized constellation of injuries caused by the direct application of force to an infant or young child, resulting in trauma to the head, intracranial contents, and/or neck, with potentially devastating health outcomes. Mechanisms of AHT include impulsive injurious acts, such as violent shaking and impact, often due to caregiver frustration or exhaustion. Subdural and retinal hemorrhage, and associated extracranial injury (fractures, abdominal trauma), are common. Suspected victims require laboratory/diagnostic testing and occult injury screening, as well as protective measures by investigative authorities to ensure safety. Medicolegal controversies persist around AHT diagnosis, including alternative hypotheses proffered in court by skeptics despite advances in scientific understanding, biomechanical research, neuroimaging techniques, and perpetrator confessions. Pediatricians play a key role in prevention and reduction of AHT morbidity and mortality through anticipatory guidance and caregiver education about the risks of shaking, normal infant development and behavior, and encouragement of stress reduction strategies.

Abstract
OBJECTIVE Despite established risk factors, abusive head trauma (AHT) continues to plague our communities. Cerebrovascular accident (CVA), depicted as areas of hypodensity on CT scans or diffusion restriction on MR images, is a well-known consequence of AHT, but its etiology remains elusive. The authors hypothesize that a CVA, in isolation or in conjunction with other intracranial injuries, compounds the severity of a child's injury, which in turn leads to greater health care utilization, including surgical services, and an increased risk of death. METHODS The authors conducted a retrospective observational study to evaluate data obtained in all children with AHT who presented to Le Bonheur Children's Hospital (LBCH) from January 2009 through August 2016. Demographic, hospital course, radiological, cost, and readmission information was collected. Children with one or more CVA were compared with those without a CVA. RESULTS The authors identified 282 children with AHT, of whom 79 (28%) had one or more CVA. Compared with individuals without a CVA, children with a stroke were of similar overall age (6 months), sex (61% male), and race (56% African-American) and had similar insurance status (81% public). Just under half of all children with a stroke (38/79, 48%) were between 1-6 months of age. Thirty-five stroke patients (44%) had a Grade II injury, and 44 (56%) had a Grade III injury. The majority of stroke cases were bilateral (78%), multifocal (85%), associated with an overlying subdural hematoma (86%), and were watershed/hypoperfusion in morphology (73%). Thirty-six children (46%) had a hemispheric stroke. There were a total of 48 neurosurgical procedures performed on 28 stroke patients. Overall median hospital length of stay (11 vs 3 days), total hospital charges ($13.8 vs $6.6 million), and mean charges per patient ($174,700 vs $32,500) were significantly higher in the stroke cohort as a whole, as well as by injury grade (II and III). Twenty children in the stroke cohort (25%) died as a direct result of their AHT, whereas only 2 children in the nonstroke cohort died (1%). There was a 30% readmission rate within the first 180-day postinjury period for patients in the stroke cohort, and of these, approximately 50% required additional neurosurgical intervention(s). CONCLUSIONS One or more strokes in a child with AHT indicate a particularly severe injury. These children have longer hospital stays, greater hospital charges, and a greater likelihood of needing a neurosurgical intervention (i.e., bedside procedure or surgery). Stroke is such an important predictor of health care utilization and outcome that it warrants a subcategory for both Grade II and Grade III injuries. It should be noted that the word "stroke" or "CVA" should not automatically imply arterial compromise in this population.

Abstract
BACKGROUND Pediatric head trauma, including abusive head trauma, is a significant cause of morbidity and mortality. OBJECTIVE The purpose of this research was to identify and evaluate radiologic interpretation errors of head CTs performed on abusive and non-abusive pediatric head trauma patients from a community setting referred for a secondary interpretation at a tertiary pediatric hospital. MATERIALS AND METHODS A retrospective search identified 184 patients <5 years of age with head CT for known or potential head trauma who had a primary interpretation performed at a referring community hospital by a board-certified radiologist. Two board-certified fellowship-trained neuroradiologists at an academic pediatric hospital independently interpreted the head CTs, compared their interpretations to determine inter-reader discrepancy rates, and resolved discrepancies to establish a consensus second interpretation. The primary interpretation was compared to the consensus second interpretation using the RADPEER™ scoring system to determine the primary interpretation-second interpretation overall and major discrepancy rates. MRI and/or surgical findings were used to validate the primary interpretation or second interpretation when possible. The diagnosis of abusive head trauma was made using clinical and imaging data by a child abuse specialist to separate patients into abusive head trauma and non-abusive head trauma groups. Discrepancy rates were compared for both groups. Lastly, primary interpretations and second interpretations were evaluated for discussion of imaging findings concerning for abusive head trauma. RESULTS There were statistically significant differences between primary interpretation-second interpretation versus inter-reader overall and major discrepancy rates (28% vs. 6%, P=0.0001; 16% vs. 1%, P=0.0001). There were significant differences in the primary interpretation-second interpretation overall and major discrepancy rates for abusive head trauma patients compared to non-abusive head trauma patients (41% vs 23%, P=0.02; 26% vs. 12%, P=0.03). The most common findings resulting in major radiologic interpretation errors were fractures and subdural hemorrhage. Differences in the age of the patient and the percentage of patients with hemorrhage were statistically significant between the abusive head trauma versus non-abusive head trauma groups, while no statistical difference was identified for skull fractures, ischemia, head CT radiation dose, or presence of multiplanar or 3-D reformatted images. The second interpretation more frequently indicated potential for abusive head trauma compared to the primary interpretation (P=0.0001). MRI and/or surgical findings were in agreement with the second interpretation in 29/29 (100%) of patients with discrepancies. CONCLUSION A high incidence of radiologic interpretation errors may occur in pediatric trauma patients at risk for abusive head trauma who are referred from a community hospital. This suggests value for second interpretations of head CTs at a tertiary pediatric hospital for this patient population.

Abstract
BACKGROUND AND PURPOSE MR imaging with sedation is commonly used to detect intracranial traumatic pathology in the pediatric population. Our purpose was to compare nonsedated ultrafast MR imaging, noncontrast head CT, and standard MR imaging for the detection of intracranial trauma in patients with potential abusive head trauma. MATERIALS AND METHODS A prospective study was performed in 24 pediatric patients who were evaluated for potential abusive head trauma. All patients received noncontrast head CT, ultrafast brain MR imaging without sedation, and standard MR imaging with general anesthesia or an immobilizer, sequentially. Two pediatric neuroradiologists independently reviewed each technique blinded to other modalities for intracranial trauma. We performed interreader agreement and consensus interpretation for standard MR imaging as the criterion standard. Diagnostic accuracy was calculated for ultrafast MR imaging, noncontrast head CT, and combined ultrafast MR imaging and noncontrast head CT. RESULTS Interreader agreement was moderate for ultrafast MR imaging (κ = 0.42), substantial for noncontrast head CT (κ = 0.63), and nearly perfect for standard MR imaging (κ = 0.86). Forty-two percent of patients had discrepancies between ultrafast MR imaging and standard MR imaging, which included detection of subarachnoid hemorrhage and subdural hemorrhage. Sensitivity, specificity, and positive and negative predictive values were obtained for any traumatic pathology for each examination: ultrafast MR imaging (50%, 100%, 100%, 31%), noncontrast head CT (25%, 100%, 100%, 21%), and a combination of ultrafast MR imaging and noncontrast head CT (60%, 100%, 100%, 33%). Ultrafast MR imaging was more sensitive than noncontrast head CT for the detection of intraparenchymal hemorrhage (P = .03), and the combination of ultrafast MR imaging and noncontrast head CT was more sensitive than noncontrast head CT alone for intracranial trauma (P = .02). CONCLUSIONS In abusive head trauma, ultrafast MR imaging, even combined with noncontrast head CT, demonstrated low sensitivity compared with standard MR imaging for intracranial traumatic pathology, which may limit its utility in this patient population.

Abstract
Fatal, allegedly inflicted pediatric head trauma remains a controversial topic in forensic pathology. Recommendations for systematic neuropathologic evaluation of the brains of supposedly injured infants and children usually include the assessment of long white matter tracts in search of axonopathy - specifically, diffuse axonal injury. The ability to recognize, document, and interpret injuries to axons has significant academic and medicolegal implications. For example, more than two decades of inconsistent nosology have resulted in confusion about the definition of diffuse axonal injury between various medical disciplines including radiology, neurosurgery, pediatrics, neuropathology, and forensic pathology. Furthermore, in the pediatric setting, acceptance that "pure" shaking can cause axonal shearing in infants and young children is not widespread. Additionally, controversy abounds whether or not axonal trauma can be identified within regions of white matter ischemia - a debate with very significant implications. Immunohistochemistry is often used not only to document axonal injury, but also to estimate the time since injury. As a result, the estimated post-injury interval may then be used by law enforcement officers and prosecutors to narrow "exclusive opportunity" and thus, identify potential suspects. Fundamental to these highly complicated and controversial topics is a philosophical understanding of the diffuse axonal injury spectrum disorders.

Abstract
"Shaken baby syndrome" is a term often used by the physicians and public to describe abusive trauma inflicted on infants and young children. Advances in the understanding of the mechanisms and the associated clinical spectrum of injury has lead us to modify our terminology and address it as "abusive trauma" (AT). Pediatric abusive head trauma is defined as an injury to the skull or intracranial contents of an infant or a young child (< 5 y age) due to inflicted blunt impact and/or violent shaking. This chapter focuses on the imaging aspects of childhood abusive trauma along with a brief description of the mechanism and pathophysiology of abusive injury. The diagnosis of AT is not always obvious, and abusive injuries in many infants may remain unrecognized. Pediatricians should be cognizant of AT since pediatricians play a crucial role in the diagnosis, management and prevention of AT.

Abstract
Child abuse or nonaccidental trauma is a major problem worldwide; in Spain, there are about 12,000 victims per year. The detection of specific lesions or findings that are incongruent with the reported mechanism of trauma mean that radiologists are often the physician responsible for sounding the alarm in cases of abuse. The triad consisting of subdural hematoma, metaphyseal fracture, and posterior rib fractures is very characteristic of the battered child syndrome. The finding of acute and chronic lesions in the same patient is highly specific for nonaccidental trauma. Fractures of long bones in patients who have yet begun to walk should also alert to possible child abuse. Lesions that are highly specific for abuse, such as classic metaphyseal fractures or posterior rib fractures, can be difficult to demonstrate radiographically and are usually clinically occult. The American College of Radiology (ACR) protocols recommend obtaining three separate X-rays of each upper and lower limb. It is important to use X-ray systems that give high resolution images with low kilovoltage (50-70 kvp) and appropriate milliamperage. A skeletal survey consisting of a series of images collimated to each body region is recommended for all children under the age of two years in whom abuse is suspected. A follow-up skeletal survey about two weeks after the initial survey is useful for detecting new fractures and for assessing the consolidation of others, which helps in dating the lesions. Head injuries are the leading cause of death in abused children. Although computed tomography is the first neuroimaging technique in nonaccidental trauma, magnetic resonance imaging of the head can better characterize the lesions seen on computed tomography and can help to estimate the age of the lesions.

Abstract
OBJECTIVE The purpose of this article is to use a mechanism-based approach to review the neuroimaging findings of abusive head trauma to infants. Advanced neuroimaging provides insights into not only the underlying mechanisms of craniocerebral injuries but also the long-term prognosis of brain injury for children on whom these injuries have been inflicted. CONCLUSION Knowledge of the traumatic mechanisms, the key neuroimaging findings, and the implications of functional imaging findings should help radiologists characterize the underlying causes of the injuries inflicted, thereby facilitating effective treatment.

Abstract
Head trauma is the leading cause of death in child abuse cases and one of the important issues in the care of abused children. Since the Child Abuse Prevention Law was enforced in 2000 in Japan, various measures have been taken to prevent child abuse over the following decade. Accordingly, medical research on abusive head trauma (AHT) has advanced, leading to significant progress in the medical diagnosis of AHT. This progress has been brought about by (1) the widespread establishment of child protection teams (CPTs) at core hospitals, (2) the progress in neuroradiological imaging and ophthalmoscopic technologies, and (3) the introduction of postmortem imaging. However, the pathological condition of patients with AHT, particularly that of the diffuse brain swelling type, still remains poorly understood. As a result, no clear treatment strategies for AHT have been developed and no treatment outcomes have been improved to date. The development of new treatment strategies for AHT and the construction of a comprehensive database that supports clinical studies are required in the future.

Abstract
Abusive head trauma is the leading cause of death in child abuse cases. The majority of victims are infants younger than 1 year old, with the average age between 3 and 8 months, although these injuries can be seen in children up to 5 years old. Many victims have a history of previous abuse and the diagnosis is frequently delayed. Neuroimaging is often crucial for establishing the diagnosis of abusive head trauma as it detects occult injury in 37% of cases. Several imaging patterns are considered to be particularly associated with abusive head trauma. The presence of subdural hematoma, especially in multiple locations, such as the interhemispheric region, over the convexity and in the posterior fossa, is significantly associated with abusive head trauma. Although CT is the recommended first-line imaging modality for suspected abusive head trauma, early MRI is increasingly used alongside CT because it provides a better estimation of shear injuries, hypoxic-ischemic insult and the timing of lesions. This article presents a review of the use and clinical indications of the most pertinent neuroimaging modalities for the diagnosis of abusive head trauma, emphasizing the newer and more sensitive techniques that may be useful to better characterize the nature and evolution of the injury.

Abstract
Abusive head trauma (AHT) is the leading cause of morbidity and mortality among abused children, yet the neuroanatomical underpinnings of AHT outcome is incompletely understood. The aim of this study was to characterize white matter (WM) abnormalities in infants with AHT using diffusion tensor imaging (DTI) and determine which microstructural abnormalities are associated with poor outcome. Retrospective DTI data from 17 infants (>3 months) with a diagnosis of AHT and a comparison cohort of 34 term infants of similar post-conceptual age (PCA) were compared using a voxel-based DTI analysis of cerebral WM. AHT cases were dichotomously classified into mild/moderate versus severe outcome. Clinical variables and conventional imaging findings were also analyzed in relation to outcome. Outcomes were classified in accordance with the Pediatric Cerebral Performance Category Score (PCPCS). Reduced axial diffusivity (AD) was shown in widespread WM regions in the AHT infants compared with controls as well as in the AHT severe outcome group compared with the AHT mild/moderate outcome group. Reduced mean diffusivity (MD) was also associated with severe outcome. Radial diffusivity (RD), conventional magnetic resonance findings, brain metric measurements, and clinical/laboratory variables (with the exception of Glascow Coma Scale) did not differ among AHT outcome groups. Findings support the unique role of DTI techniques, beyond conventional imaging, in the evaluation of microstructural WM injury of AHT. Reduced AD (likely reflecting axonal damage) and MD were associated with poor clinical outcome. DTI abnormalities may uniquely reflect AHT patterns of axonal injury that are not characterized by conventional imaging, which may have both therapeutic and prognostic implications.

Abstract
UNLABELLED Neurologic complications of bacterial meningitis can occur any time during the course of the disease and some of them need neurosurgical aproach. OBJECTIVE to determine the incidence of neurologic complications of bacterial meningitis in children requring neurosurgical treatment. MATERIAL AND METHODOLOGY a total of 277 children were followed and treated for bacterial meningitis at the Clinic of Infectious Diseases in Prishtina. The authors have analyzed cases who developed acute neurologic complications and treatment procedures. RESULTS of the 277 children treated for bacterial meningitis, due to the suspicion for neurologic complications, 109 children underwent a head computerized tomography scan. About 47 cases (43%) had evident structural abnormalities while only 15/277 cases (5%) required neurosurgical treatment; 9/38 cases with subdural collections, 5 cases with hydrocephalus and 1 case of spinal abscess. CONCLUSION Neurosurgical intervention were not common in pediatric bacterial meningitis cases (5%) but were highly significant in cases complicated with acute neurologic complications (32%).

Abstract
The appropriate imaging for pediatric patients being evaluated for suspected physical abuse depends on the age of the child, the presence of neurologic signs and symptoms, evidence of thoracic or abdominopelvic injuries, and whether the injuries are discrepant with the clinical history. The clinical presentations reviewed consider these factors and provide evidence-based consensus recommendations by the ACR Appropriateness Criteria(®) Expert Panel on Pediatric Imaging.

Abstract
Physical abuse associated with nonaccidental trauma (NAT) affects approximately 144,000 children per year in the USA and, frequently, these injuries affect the developing brain. Most infants with suspected NAT are initially evaluated by skull X-rays and computed tomography to determine whether fractures are present, the severity of the acute injury and the need for urgent neurosurgical intervention. Increasingly, magnetic resonance imaging (MRI) is conducted as it provides additional diagnostic and prognostic information about the extent and nature of the injury. In this review, we examine 4 MRI techniques as they apply to children who present acutely after NAT. Susceptibility-weighted imaging is a 3-D high-resolution MRI technique that is more sensitive than conventional imaging in detecting hemorrhagic lesions that are often associated with diffuse axonal injury (DAI). Magnetic resonance spectroscopy acquires metabolite information reflecting neuronal integrity and function from multiple brain regions and provides a sensitive, noninvasive assessment of neurochemical alterations that offers early prognostic information regarding outcome. Diffusion-weighted imaging (DWI) is based on differences in the diffusion of water molecules within the brain and has been shown to be very sensitive in the early detection of ischemic injury. It is now being used to study the direct effects of traumatic injury as well as those due to secondary ischemia. Diffusion tensor imaging is a form of DWI and allows better evaluation of white matter fiber tracts by taking advantage of the intrinsic directionality (anisotropy) of water diffusion in the human brain. It has been shown to be useful in identifying white matter abnormalities after DAI when conventional imaging appears normal. Although these imaging methods have been studied primarily in adults and children with accidental traumatic brain injury, it is clear that they have the potential to provide additional value in the imaging and clinical evaluation of children with NAT.

Neuroimaging evaluation of non-accidental head trauma with correlation to clinical outcomes: a review of 57 cases. J Pediatr 2009; 154:573-7. [PMID: 19028392 PMCID: PMC2762656 DOI: 10.1016/j.jpeds.2008.09.051] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2008] [Revised: 08/16/2008] [Accepted: 09/29/2008] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To review the clinical presentation and neuroimaging findings in patients with high clinical suspicion for non-accidental trauma (NAT) of the head, to investigate associations between imaging findings and long-term neurologic outcome in abused children. STUDY DESIGN A retrospective review of 57 cases of NAT of the head from a single institution was performed. Neuroimaging studies (computed tomography [CT] and magnetic resonance imaging [MRI]) were reviewed by a senior neuroradiologist, a neuroradiology fellow, and a radiology resident. Clinical history and physical findings, including retinal examination, imaging, and follow-up assessment, were reviewed. RESULTS The mean time between the patient's arrival at the hospital and CT and MRI imaging was 2.9 hours and 40.6 hours, respectively. The most common clinical presentation was mental status changes, seen in 47% of patients. The most common neuroimaging finding was subdural hematoma, seen in 86% of patients. In the 47 patients who underwent both MRI and CT, 1 case of suspected NAT was missed on head CT. CT detected signs of global ischemia in all 11 patients who died (mean time after arrival at the hospital until undergoing CT, 1.1 hours). MRI detected additional signs of injury in patients who developed mild to moderate developmental delay. CONCLUSION CT was able to detect evidence of NAT of the head in 56 of 57 abused children included in our cohort and predicted severe neurologic injury and mortality. MRI was useful in detecting additional evidence of trauma, which can be helpful in risk stratification for neurologic outcomes as well in providing confirming evidence of repeated injury.

Abstract
OBJECTIVE Distinguishing abusive head trauma in young children from other diseases by symptoms is difficult in practice. Comparisons between abusive and nonabusive head trauma in young children in Japan, where computed tomography is widely and easily available, might contribute to identifying markers of abusive head trauma that differ from that in Western countries. The objective of this study was to compare the characteristics of abusive and nonabusive head trauma in young children in Japan. METHODS A comparative case series study involving a retrospective medical chart and social work record review of children who were aged 0 to 2 years, visited the National Center for Child Health and Development (Tokyo, Japan) from March 1, 2002, to December 31, 2005, and underwent computed tomography scanning because of suspected intracranial injury was performed. Patients (N = 260) were identified and classified as having either abusive or nonabusive head trauma on the basis of the published definition. Demographic and perinatal characteristics, injury history, clinical presentation, and outcomes were compared by using chi2 and Fisher's exact tests. RESULTS Patients with abusive head trauma were significantly younger than patients with nonabusive head trauma and had a peak at approximately 2 to 4 and 7 to 9 months. Patients with abusive head trauma more likely presented no injury history by the caregiver, neurologic symptoms (unconsciousness, seizure, paralysis), subdural hemorrhage, and retinal hemorrhages. Although patients with abusive head trauma had severe clinical outcomes, only 32% of them were separated from the caregiver by social welfare services. CONCLUSIONS This study highlights the several clinical markers to detect abusive head trauma at a medical visit, including an absence of injury history, neurologic symptoms, subdural hemorrhage, and retinal hemorrhage. These markers can be used to detect abusive head trauma cases by physicians and social welfare workers to protect children from additional abuse.

Unilateral hypoxic-ischemic injury in young children from abusive head trauma, lacking craniocervical vascular dissection or cord injury. Pediatr Radiol 2008; 38:164-74.

Abstract
BACKGROUND Abusive head trauma (AHT) in young children usually has a severe outcome when associated with hypoxic-ischemic encephalopathy (HIE), which is best characterized by MRI in the acute or subacute phase utilizing diffusion-weighted imaging (DWI). HIE in this setting has been hypothesized to result from stretching of the spinal cord, brainstem, or vasculature. OBJECTIVE To provide clinical correlation in patients with unilateral HIE and to postulate a mechanism in the setting of suspected AHT. MATERIALS AND METHODS IRB approval was obtained. Over a 5-year period, the medical records and images were reviewed of the 53 children < or = 3 years of age who presented with acute head trauma according to the hospital registry. The children were subselected in order to determine how many suffered either HIE or AHT, and to detect those with unilateral HIE. RESULTS In 11 of the 53 children, the etiology of the head trauma was highly suspicious for abuse. In 38 the head trauma was accidental and in 4 the trauma was of unknown etiology and at the time of this report was unresolved legally. Of the 53, 4 suffered HIE confirmed by CT or MRI. In three of these four with HIE the trauma was considered highly suspicious for AHT. Two of these three were the only patients with unilateral HIE, and both (7 months and 14 months of age) presented with early subacute phase HIE seen on DW MRI (range 4-7 days) and are described in detail with clinical correlation. The third child with AHT and HIE had bilateral findings. In the fourth patient the HIE was bilateral and was considered accidental. The work-up for both patients with unilateral HIE included head CT, craniocervical MRI, and craniocervical MR angiography (MRA). In both, there was mostly unilateral, deep white matter restricted diffusion, with subdural hematomas that were small compared to the extent of hypoxic-ischemic insult, and no skull fracture. Craniocervical MRA and axial thin-section fat-saturation images were negative for dissection, brainstem, or cord injury. Legal authorities obtained a confession of inflicted injury in one and a partial confession in the second (which did not fit the extent of injury). Five other children with HIE (based on DWI) were found during this period who had not suffered head trauma; all were bilateral insults. CONCLUSION HIE associated with AHT might present with largely unilateral white matter injury on DWI following extensive cortical infarction. We propose that unilateral HIE in a young child might be a sign of AHT and might result from cervical vascular compression, whether from kinking during hyperflexion/hyperextension or from direct strangulation.

Abstract
Increasingly, radiologists are encouraged to have protocols for all imaging studies and to include imaging guidelines in care pathways set up by the referring clinicians. This is particularly advantageous in MRI where magnet time is limited and a radiologist's review of each patient's images often results in additional sequences and longer scanning times without the advantage of improvement in diagnostic ability. The difficulties of imaging small children and the challenges presented to the radiologist as the brain develops are discussed. We present our protocols for imaging the brain and spine of children based on 20 years experience of paediatric neurological MRI. The protocols are adapted to suit children under the age of 2 years, small body parts and paediatric clinical scenarios.

Abstract
Choice of imaging modalities should be based on scientific proof and best practice guidelines. However, in the neonatal age group there is a paucity of medical evidence, and imaging is often guided by local experience, availability of equipment and expertise, and by logistical factors. This paper discusses possible indications for CT in the neonate, the associated radiation protection issues, common CT findings and potential pitfalls in technique and image interpretation. Due to the particular range of abnormalities in this age group, imaging must be tailored to the individual, and should in most cases be done in specialist units.

Abstract
Non-accidental head injury in infants is not uncommon and is associated with significant morbidity and mortality. It is therefore important to identify it at the earliest opportunity so that appropriate intervention can be made which protects the child from further harm. The whole topic is controversial and the aim of this paper, in question and answer format, is to review some of the more controversial areas to give an overview of the neuroimaging features of this condition. The author has drawn on his clinical and medicolegal experience of these cases, and the review is based upon questions commonly encountered in Court.

Abstract
AIMS To review the neuroimaging of a series of infants and young children admitted to hospital with subdural haemorrhage (SDH). METHODS Neuroradiological investigations of 74 children under 2 years of age, from South Wales and southwest England, in whom an SDH or subdural effusion had been diagnosed between 1992 and 2001, were reviewed. Two paediatric neuroradiologists blinded to the original radiological report reviewed all the relevant images. RESULTS Neuroradiological review of images identified radiological features which were highly suggestive of non-accidental head injury (NAHI). Interhemispheric haemorrhages and SDHs in multiple sites or of different densities were almost exclusively seen in NAHI. MRI was more sensitive in identifying SDHs of different signal characteristics, posterior and middle cranial fossa bleeds, and parenchymal changes in the brain. CT scans, if performed with suboptimal protocols, were likely to miss small subdural bleeds. CONCLUSIONS Guidelines for neuroimaging in suspected NAHI are recommended. A radiologist with experience in NAHI should report or review these scans. The initial investigation should be CT, but MRI will also be necessary in most cases. Head CT should be an integral part of the skeletal survey in all infants less than 6 months of age referred for child protection investigation, and in children less than 2 years where child abuse is suspected and there are neurological signs, retinal haemorrhages, or fractures.

Abstract
Childhood cerebrovascular disease is characterised by a wide range of relatively rare conditions. The management of a selection of some of the more frequently encountered, complex conditions is reviewed. The key to achieving the optimal therapeutic strategy for the individual child is multidisciplinary team management within a specialist neurovascular team. Access to rehabilitation is crucial.

Abstract
AIM To identify the potential national variation in non-accidental injury (NAI) imaging in England, Scotland and Wales. MATERIALS AND METHODS A postal survey was sent to 323 hospitals with both paediatric and radiology departments. These were identified by a search through the Medical Directory. RESULTS One hundred and thirteen of 323 postal questionnaires were returned within the study period (35%). Sixteen were excluded from the study because either no NAI imaging was performed at that institution or an incorrect address had been used. The total number of completed questionnaires was 97 (30%). Extensive variation was seen in all aspects of NAI imaging including imaging techniques used, total case numbers, follow-up imaging and those who report the NAI imaging. CONCLUSIONS There is currently no national protocol that incorporates all aspects of NAI imaging in England, Scotland and Wales. Extensive variation in practice has been shown by this survey. Further standardization of NAI imaging practice is required. The draft BSPR skeletal survey guidelines and routine neurological imaging is recommended.
