The radiographic approach to child abuse

Pediatric skeletal injuries in emergency department; an alarm of child maltreatment in Egypt: A cross-sectional study

BACKGROUND

Child physical abuse, a type of child maltreatment (CM), poses a significant global public health concern. Nonaccidental fractures and soft tissue injuries, which encompass any action that directly or indirectly harms a child, are the primary indicators of physical abuse in children.

OBJECTIVE

This study aimed to investigate the prevalence, risk factors, and outcomes of accidental and nonaccidental skeletal fractures in a sample of Egyptian children.

METHODS

A cross-sectional analytical study was conducted between March 2022 and August 2022. A total of 156 children who presented with skeletal injuries and attended Mobarak Central Hospital were enrolled. Patients were subjected to full history taking, complete examination, and investigations. A structured questionnaire was administered to all the legal guardians.

RESULTS

Physical abuse was reported in 22.4 % of cases, while medical neglect was reported in 19.9 % of cases. The incidence of physical abuse was notably higher among children whose fathers were smokers and/or drug addicts (p ≤ 0.05). The most common form of physical abuse was hitting (94.3 %). Among skeletal injuries, fractures were predominant (94.3 %), primarily closed fractures associated with contusions. Fractures of the upper limb accounted for the highest incidence (94.3 %) of skeletal injuries, and 60 % of physically abused children experienced moderate-severity injuries.

CONCLUSION

The most common fracture observed in abused children is the upper limb fracture, typically involving a single bone. Clinicians should be more vigilant in suspecting abuse, even in cases where there is an isolated fracture, and advocate for the development of parental training programs.

Identification and Evaluation of Non-Accidental Trauma in the Pediatric Population: A Clinical Review

Non-accidental trauma (NAT) is a major cause of morbidity and mortality for children around the world and most significantly impacts children under one year of age. Prompt and comprehensive treatment of these children relies on a high index of suspicion from any medical provider that treats pediatric patients. This review discusses those most at risk for experiencing NAT, and common initial presentations, to assist providers in the identification of potential victims. In addition, this review provides guidance on the recommended workup for these patients so that the full extent of associated injuries may be identified and the appropriate healthcare team may be assembled.

Bilateral Distal Humeral Physeal Separation-From Birth Trauma to Family Trauma

Introduction

Chondro-epiphyseal separation of the distal humerus is a rare injury, which can occur as a consequence of excessive traction on the upper extremity accompanying a dystocic birth or one complicated by cephalopelvic disproportion. Such fracture patterns can also result from a combination of rotatory and shear forces, also typically seen following child abuse. It can be easily mistaken for a posterior elbow dislocation, creating a delay in diagnosis. Since unossified cartilage cannot be seen radiographically, these injuries are better appreciated by ultrasound or magnetic resonance imaging.

Case Report

We present a case of an 8-day-old neonate who presented with pseudoparesis of the left arm following birth. Posterior displacement of the elbow joint was identified on the radiograph. On ultrasound, a trans-physical supracondylar distal humerus fracture was identified. This was presumed as trauma secondary to a difficult delivery. At the 11th week of follow-up, the patient presented with a fracture of the right proximal tibia, followed by a fracture shaft left femur at 5 months of follow-up. Chest X-ray at this time revealed uniting rib fractures with callus formation. After ruling out any congenital collagen disorder (osteogenesis imperfecta), the patient was diagnosed with a case of battered baby syndrome. The case was reported to child protection services and parents were questioned and counseled for the same.

Conclusion

This case report highlights the importance of a high degree of suspicion of child abuse in any child with a rare fracture pattern, uncommon serial fracture occurrence, and unconventional clinic-radiological presentation.

Common and Consequential Fractures That Should Not Be Missed in Children

Missed or delayed diagnosis of fractures in children is not uncommon owing to their immature skeletons, unique fracture patterns, and distinctive radiologic findings. The term occult is used to describe radiographically subtle fractures. Some of these fractures can be associated with excellent outcomes despite the pitfalls of delayed diagnosis. However, a subset of these injuries have more guarded prognoses when missed, despite their harmless radiographic appearance. A high index of suspicion should be maintained when treating pediatric extremity injuries with clinical findings disproportionate to a benign-appearing radiograph. Moreover, overreliance on radiology reports can perpetuate diagnostic error. In cases of discrepancy, timely follow-up for repeat examination or immediate advanced imaging can help avoid missed diagnoses. Most critically, the one diagnosis not to miss is nonaccidental trauma, as continued exposure to abuse puts the child at risk of further injury and death. [Pediatr Ann. 2022;51(9):e357-e363.].

Imaging Review of Normal and Abnormal Skeletal Maturation

The growing skeleton undergoes well-described and predictable normal developmental changes, which may be misinterpreted a as pathologic condition at imaging. Primary and secondary ossification centers (SOCs), which form the diaphysis and the epiphysis of long bones, respectively, are formed by endochondral and intramembranous ossification processes. During skeletal maturation, the SOCs may appear irregular and fragmented, which should not be confused with fractures, osteochondritis dissecans, and osteochondrosis. These normal irregularities are generally symmetric with a smooth, round, and sclerotic appearance, which are aspects that help in the differentiation. The metaphysis, epiphysis, and growth plates or physes are common sites of injuries and normal variants in the pediatric skeleton. The metaphysis contains the newly formed bone from endochondral ossification and is highly vascularized. It is predisposed to easy spread of infections and bone tumors. The physis is the weakest structure of the immature skeleton. Injuries to this location may disrupt endochondral ossification and lead to growth disturbances. Pathologic conditions of the epiphyses may extend into the articular surface and lead to articular damage. At MRI, small and localized foci of bone marrow changes within the epiphysis and metaphysis are also a common finding. These can be related to residual red marrow (especially in the metaphysis of long bones and hindfoot), focal periphyseal edema (associated with the process of physeal closure), and ultimately to a normal ossification process. The authors review the imaging appearance of normal skeletal maturation and discuss common maturation disorders on the basis of developmental stage and location. ^©RSNA, 2022.

Pearls and Pitfalls of Thoracic Manifestations of Abuse in Children

Child abuse is a broad term that includes, but is not limited to, physical or emotional harm, neglect, sexual abuse, and exploitation. In 2018 in the United States, there were nearly 700,000 victims of such maltreatment, of which 1700 children died. The majority of deaths occur in infants and toddlers under 3 years of age. While clinical signs and symptoms may raise suspicion for inflicted injury, such as bruising in young infants, imaging often plays a central role in identifying and characterizing nonaccidental trauma. The purpose of this article is to discuss the array of inflicted traumatic injuries to the thorax in children. Rib fractures are among the most common and telling features of physical abuse, especially in infants. The locations of such fractures and differences in appearance while healing will be presented, along with potential mimics and pitfalls. Less typical fractures seen in abuse will also be reviewed, including those of the sternum, clavicle, spine, and scapula. Finally, uncommon injuries to the lungs, heart and esophagus will also be considered.

Debunking Fringe Beliefs in Child Abuse Imaging: AJR Expert Panel Narrative Review

Child abuse is a global public health concern. Injuries from physical abuse may be clinically occult and not appreciable on physical examination. Imaging is therefore critical in identifying and documenting such injuries. The radiologic approach for a child who has potentially been abused has received considerable attention and recommendations according to decades of experience and rigorous scientific study. Nonetheless, fringe beliefs describing alternative explanations for child abuse-related injuries have emerged and received mainstream attention. Subsequently, imaging findings identified in abused children have been attributed to poorly supported underlying medical conditions, clouding the evidence basis for radiologic findings indicative of nonaccidental trauma. Fringe beliefs that attribute findings seen in child abuse to alternate pathologies such as genetic disorders, birth trauma, metabolic imbalances, vitamin D deficiency, and short-distance falls typically have limited evidence basis and lack professional society support. Careful review of the scientific evidence and professional society consensus statements is important in differentiating findings attributable to child abuse from fringe beliefs used to discount the possibility that a child's constellation of injuries is consistent with abuse. This review refutes fringe beliefs used to provide alternative explanations in cases of suspected child abuse and reinforces the key literature and scientific consensus regarding child abuse imaging.

A review of current imaging techniques used for the detection of occult bony fractures in young children suspected of sustaining non-accidental injury

Non-accidental injuries remain a leading cause of preventable morbidity and mortality in young children. The accurate identification of the full spectrum of injuries in children presenting with suspected abuse is essential to ensure the appropriate protective intervention is taken. The identification of occult bone fractures in this cohort is important as it raises the level of concern about the mechanism of injury and maintaining the child's safety. Radiographic imaging remains the modality of choice for skeletal assessment; however, current studies report concerns regarding the ability of radiographs to detect certain fractures in the acute stage. As such, alternative modalities for the detection of fractures have been proposed. This article reviews the current literature regarding fracture detectability and radiation dose burden of imaging modalities currently used for the assessment of occult bony injury in young children in whom non-accidental injury is suspected.

Multiple Abusive Fractures in an Infant With a Concurrent Parathyroid Hormone-Related Peptide-Secreting Renal Tumor: Abusive Fractures Accompanying a Parathyroid Hormone-Related Peptide-Secreting Tumor

BACKGROUND

When evaluating an infant with unexplained fractures for child abuse, it is important to evaluate for possible causes of underlying bone fragility.

CASE

A 7-month-old infant was found to have a parathyroid hormone (PTH)-related peptide-secreting mesoblastic nephroma. In spite of having an elevated serum calcium, depressed serum phosphate, and high levels of PTH-related peptide, he had no demineralization or other hyper parathyroid-related bone changes. Instead, he had multiple classic metaphyseal lesions, fractures of differing ages including a proximal clavicle fracture, and current and past bruising. No fractures typical of bone insufficiency were present. These findings are highly indicative of abuse in addition to his hormone-secreting tumor.

CONCLUSIONS

In spite of this child's abuse findings, endogenous or tumor-related hyper PTH should be in the differential of underlying bone fragility. Children with disorders that could cause injury susceptibility can also be abused.

Fractures of child abuse

The objective of this paper is to review common challenges when evaluating fractures in the setting of possible child abuse and approaches to navigate them. This paper reviews the variety of imaging modalities available for evaluating child abuse and the advantages/disadvantages of each. Additionally, the authors discuss management of equivocal fractures, including the impact of double-reading skeletal surveys. The complexity of dating the acuity of fractures in young children is discussed. Utilizing the knowledge of fracture type, fracture patterns and patient history, as well as in the setting of cardiopulmonary resuscitation, the authors provide methods for determining the likelihood of abuse.

CORRELATION BETWEEN FRACTURES AND ABUSE IN CHILDREN: A RETROSPECTIVE ANALYSIS

Objective:

The aim of this work is to provide evidence for the relationship between suspicion and diagnosis of cases of child abuse and fractures, since, in national literature, studies are still scarce on the subject.

Methods:

Retrospective study involving electronic medical records of a public reference hospital, in a city of the state of São Paulo, in a 8-year period (2010 to 2018). Cases involving children up to 12 years of age were selected when notified as abuse and presenting fractures; data were statistically analyzed. Results: Among 83 cases of abuse, 19 patients (20.5%) had 23 different fractures. The victims were mainly boys (68.42%) with a mean age of 5 years old, who suffered physical aggression (79%). The majority had no identified aggressor (52%) and 21% were related to the mother. The fracture patterns found involved, mostly, skull fractures (43.48%) and diaphysary fractures (34.78%). Seven patients (30.43%) had other associated lesions and four patients died (21%).

Conclusion:

Despite the number of cases, it was possible to identify relevant characteristics and patterns. These data indicate that the diagnosis is underestimated and show small epidemiological differences compared with international literature. Level of Evidence II, Retrospective study.

Validating scoring systems for fracture healing in infants and young children: pilot study

BACKGROUND

Recent studies have analysed birth-related clavicular fractures to propose time frames for healing that could be applied to dating of all fractures in cases of suspected child abuse.

OBJECTIVE

To assess differences in healing rates between femoral fractures and birth-related clavicular fractures in infants and young children.

MATERIALS AND METHODS

A retrospective 5-year pilot study of femoral fractures in children younger than 3 years of age was performed. Anonymised radiographs were independently scored by two radiologists for stages of fracture healing. In cases of reader disagreement, radiographs were independently scored by a third radiologist.

RESULTS

In total, 74 radiographs (30 children) met the inclusion criteria. Fracture healing evolved over time with subperiosteal new bone formation (SPNBF) appearing first, followed by callus then remodelling. A power calculation for a single proportion, with a level of confidence of 95% and a margin of error of 5%, showed that in a definitive study, 359 radiographs would be required.

CONCLUSION

Although the overall pattern of healing is similar, in this small pilot study, the earliest times for SPNBF and callus formation in femoral fractures appeared to lag behind healing of birth-related clavicular fractures. Remodelling appeared earlier than remodelling of clavicular fractures. A power calculation has determined numbers of femoral radiographs (359) required for a definitive study.

Pediatric sternal fractures: A single center retrospective review

PURPOSE

We sought to investigate the diagnosis, management, and outcomes of pediatric sternal fractures.

METHODS

We used ICD codes to search our trauma registry and Hound Dog software to search the hospital data warehouse for all cases of radiologically confirmed sternal fracture in patients <21 years from January 1, 1997 to July 1, 2017. We extracted demographics, mechanism of injury, diagnostic modality, associated injuries, and clinical outcomes.

RESULTS

We identified 65 children with sternal fractures. 46/65 (71%) were male, with median age 11 years. 34/65 (52%) presented to our emergency department (ED) and the remainder to outpatient clinics. 41/65 (63%) were diagnosed by chest X-ray, 11/65 (17%) by chest CT, 7/65 (11%) by sternal X-ray, and 5/65 (8%) by MRI. Mechanism of injury varied by age. The majority, 50/65 (77%), were isolated injuries and there were no cardiac injuries, aortic injuries or deaths. 18/33 (45%) of those who presented initially to the ED were admitted, and of these 7/18 (39%) had isolated sternal fractures.

CONCLUSIONS

In this series, most sternal fractures were isolated with low morbidity. Sternal fracture alone should not prompt aggressive workup for intrathoracic injuries and stable patients with isolated sternal fractures can be safely followed without admission.

Usefulness of X-rays in the Differential Diagnosis of Hypophosphataemic Rickets

Rickets and osteomalacia are two related conditions linked by the lack of mineralization of bone tissue due to a disturbance of calcium and phosphate homeostasis. Some of the most characteristic features of rickets are skeletal deformities, fractures, linear and continuous periosteal reaction, and enlargement of the metaphyseal space in an irregular and frayed form. However, these radiological findings are not exclusive to these diseases, but may also originate in children who were born prematurely or in those who have suffered physical abuse or an accident. Hence, it is important to establish a differential diagnosis. All these observations can be evidenced by radiological images using a simple X-ray. The aim of this article is to show the main radiological findings that can be found in rickets and how to establish a differential diagnosis of X-linked hypophosphataemic (XLH) rickets.

Osteological evidence of metabolic diseases from a post medieval North Italy archaeological site

Skeletal lesions related to metabolic diseases in children have been systematically investigated in paleopathological literature only in recent years. This work presents an infant pathological specimen from the post-medieval cemetery of the St. Mary's Nativity church (15th-18th centuries, Segno, Trento, Trentino, Northeast Italy). The bones belonged to an individual of 9 ± 3 months of age, estimated upon an assessment of the stage of dental eruption. Metabolic diseases were diagnosed with paleopathological criteria according to previous literature. Differential diagnosis of the osteological evidence indicates a disease that might be caused by the lack of vitamin D or C. Comorbidity of vitamin C and D deficiency has been widely studied in clinical literature, particularly in children between 3 months and 5 years of age. The study of ancient osteoarchaeological materials allows us to improve our knowledge on diseases' effects on bone development in children and, in this case, it represents additional evidence of the presence of metabolic diseases in a rural contest of the Italian post-medieval period.

The detection of significant fractures in suspected infant abuse

OBJECTIVE

Skeletal survey is a commonly used means of detecting fractures in infants, and is used as a screen in suspected cases of physical abuse. It is recognised that in live infants, a repeat survey some days after a suspected episode of injury will detect more fractures than one taken shortly after the suspected injury, indicating that the latter lacks sensitivity. In infants who die soon after a suspected episode of physical abuse, the managing clinicians do not have the option of a second survey; however there is the opportunity for the microscopic examination of bones removed at autopsy. Increasingly Osteoarticular Pathology at the Manchester University NHS Foundation Trust (MFT) is being sent samples of bones from infants suspected of inflicted injury for histological examination, both from bones with fractures detected at autopsy or skeletal survey and from posterior ribs and long bone metaphyses (sites of significance in assessing for abusive injury) when there is no evidence of fracture on skeletal survey or autopsy. Here we report the results of an audit of the anonymised data from a series of such cases, to establish the sensitivity of skeletal survey (SS) to detect fractures and to define the medico-legal value of submitting bones for histological examination.

METHODS

This was an audit of skeletal injuries in 38 infants aged <18 months presenting to MFT for specialist histopathological evaluation of suspected non-accidental fractures between January 2011 and June 2017. Histopathological examination was performed on all bones submitted and compared with contact radiography of isolated bones and post-mortem skeletal surveys undertaken by specialist paediatric or musculoskeletal radiologists for the presence of fracture.

RESULTS

A total of 318 fractures were detected histologically; of these, 178 (56%) were of the ribs, 119 (37.5%) were of major limb long bones, 10 (3%) were of the skull, and 11 (3.5%) were recorded as 'other'. Excluding refractures, skeletal survey detected 54% of the fractures recorded histologically. No fractures were detected radiologically that were not seen histologically. Generally, for skeletal survey, detection rates improved with the age of the lesion, and rib fractures were more difficult to detect than long bone fractures. Ribs 5-8 were the most frequently fractured ribs, and metaphyses around the knee accounted for most metaphyseal limb long bone fractures undetected by SS.

CONCLUSION

In infants coming to post-mortem, histopathology is more sensitive than SS for the detection of clinically significant fractures. In children suspected of non-accidental injuries but with negative or equivocal SS, sampling of the anterior and posterior end of ribs 5-8 and the bones around the knee for histological examination could reveal clinically unsuspected fractures and significant evidence of physical abuse. 71% of infants showed evidence of old fractures typical of non-accidental injury.

The Risk of Assuming Abuse in an Infant with an Isolated Metaphyseal Lesion: A Case Report

CASE

The classic metaphyseal lesion, or corner fracture, is considered a strong indicator of nonaccidental trauma. In the present case, the parents brought their 8-month-old boy to a community hospital after he stopped crawling on the right leg. A knee radiograph demonstrated an isolated metaphyseal lesion, which prompted concern for child abuse. The patient was transferred to the nearest academic medical center; the pediatric radiology expert in child abuse determined that the lesion was a normal variant and not the result of abuse.

CONCLUSION

An isolated metaphyseal lesion is not pathognomonic for child abuse, and a thoughtful differential diagnosis should be considered.

Characteristics of Rib Fractures in Child Abuse-The Role of Low-Dose Chest Computed Tomography

OBJECTIVES

Our aim is to describe the radiologic characteristics of rib fractures in clinically diagnosed cases of child abuse and suggest a complementary imaging for radiographically occult injuries in highly suspicious cases of child abuse.

METHODS

Retrospective analysis of initial and follow-up skeletal surveys and computed tomography (CT) scans of 16 patients younger than 12 months were reviewed after obtaining approval from our institutional review board. The number, location, displacement, and age of the rib fractures were recorded.

RESULTS

Out of a total 105 rib fractures, 84% (87/105) were detected on the initial skeletal survey. Seventeen percent (18/105) were seen only after follow-up imaging, more than half of which (11/18) were detected on a subsequent CT. Majority of the fractures were posterior (43%) and anterior (30%) in location. An overwhelming majority (96%) of the fractures are nondisplaced.

CONCLUSIONS

Seventeen percent of rib fractures analyzed in the study were not documented on the initial skeletal survey. Majority of fractures are nondisplaced and located posteriorly or anteriorly, areas that are often difficult to assess especially in the acute stage. The CT scan is more sensitive in evaluating these types of fractures. Low-dose chest CT can be an important imaging modality for suspicious cases of child abuse when initial radiographic findings are inconclusive.

Italian guidelines on the assessment and management of pediatric head injury in the emergency department

OBJECTIVE

We aim to formulate evidence-based recommendations to assist physicians decision-making in the assessment and management of children younger than 16 years presenting to the emergency department (ED) following a blunt head trauma with no suspicion of non-accidental injury.

METHODS

These guidelines were commissioned by the Italian Society of Pediatric Emergency Medicine and include a systematic review and analysis of the literature published since 2005. Physicians with expertise and experience in the fields of pediatrics, pediatric emergency medicine, pediatric intensive care, neurosurgery and neuroradiology, as well as an experienced pediatric nurse and a parent representative were the components of the guidelines working group. Areas of direct interest included 1) initial assessment and stabilization in the ED, 2) diagnosis of clinically important traumatic brain injury in the ED, 3) management and disposition in the ED. The guidelines do not provide specific guidance on the identification and management of possible associated cervical spine injuries. Other exclusions are noted in the full text.

CONCLUSIONS

Recommendations to guide physicians practice when assessing children presenting to the ED following blunt head trauma are reported in both summary and extensive format in the guideline document.

Multiple unexplained fractures in infants and child physical abuse

When an infant presents with X-rays showing multiple unexplained fractures in various stages of healing (MUFVSH), the child is usually diagnosed with child abuse based on criteria of the Academy of Pediatrics' Committee on Child Abuse and Neglect (AAPCCAAN). Almost always, the infant is subsequently removed from the home and civil or criminal proceeding commence. It may be that healing infantile rickets or other poorly understood metabolic bone disorders of infancy are responsible for these x-rays. Activated vitamin D is a seco-steroid hormone, whose mechanism of action is genetic regulation. Lack of it can result in musculoskeletal defects known as rickets. Low calcium can also cause rickets. However, it is clear that experts for the state believe that the x-rays in these cases are so definitive as to be pathognomonic for child abuse. Therefore, if the caregivers deny abusing their infants, experts following American Academy of Pediatric's Committee on Child Abuse and Neglect. guidelines are essentially claiming that x-rays showing multiple unexplained fractures in various stages of healing are lie detector tests. However, it is not widely appreciated that the gold standard for the diagnosis of rickets is a bone biopsy, not x-rays, as radiologists miss biopsy proven rickets 80% of the time; that is, 4 out of 5 infants with rickets will have normal x-rays. In this article we provide reports of two cases and their outcomes. We discuss information about healing infantile rickets and an example of common sense medical conclusions in these cases. This information could lead to a significant reduction in the number of innocent parents having their infant removed or sent to prison.

Multiple fractures in infants who have Ehlers-Danlos/hypermobility syndrome and or vitamin D deficiency: A case series of 72 infants whose parents were accused of child abuse and neglect

Objective: To increase the level of awareness that Ehlers-Danlos/hypermobility syndrome (EDS) and vitamin D deficiency are associated with infantile fragility fractures and radiologic features that may be mistakenly reported to be caused by non-accidental trauma due to Child Abuse and Neglect (CAN).

Patients and Methods: We constructed a case series, the largest to date, of infants with EDS who were vitamin D sufficient, insufficient and deficient and infants without EDS but with documented vitamin D deficiency and radiologic evidence of rickets who presented with multiple fractures originally diagnosed as being non-accidental and caused by child abuse. These infants were referred to the outpatient Bone Health Care Clinic at Boston University Medical Campus over a 6-year (2010–2015) period. We also present 6 index cases in which the court concluded that there was no convincing evidence of child abuse and the infants were returned to their parents. Institutional Review Board (IRB) approval was obtained.

Results: We present 72 cases of infants with multiple fractures diagnosed to be caused by non-accidental trauma. All infants were younger than one year of age. Among them, 93%(67) had clinical evidence of EDS and/or a family history with a confirmed clinical diagnosis of at least one parent having EDS and the other 7%(5) without evidence of EDS had vitamin D deficiency/infantile rickets. Three of the EDS infants were diagnosed as osteogenesis imperfecta (OI)/EDS overlap syndrome. The most common fractures noted at diagnosis were ribs and extremity fractures (including classic metaphyseal lesions). Serum levels of 25-hydroxyvitamin D [25(OH)D] were reported in 48 infants (18.0 ± 8.5 ng/ml) and in 30 mothers (21.3 ± 11.7 ng/ml). Sixty-three percent (27) of the EDS infants who had their serum 25(OH)D measured were vitamin D deficient 25(OH)D<20 ng/ml and 5 were vitamin D sufficient 25(OH)D>30 ng/ml. The mean serum level for infants with vitamin D deficiency/rickets was (10.2 ± 3.0 ng/ml)

Conclusion: EDS, OI/EDS and vitamin D deficiency/infantile rickets are associated with fragility fractures in infants that can be misinterpreted as caused by non-accidental trauma due to child abuse.

Adult post-mortem imaging in traumatic and cardiorespiratory death and its relation to clinical radiological imaging

The use of post-mortem imaging is expanding throughout the world with increasing use of advanced imaging techniques, such as contrast-enhanced CT and MRI. The questions asked of post-mortem imaging are complex and can be very different, for example for natural sudden death investigation will focus on the cause, whereas for trauma the cause of death is often clear, but injury patterns may be very revealing in investigating the background to the incident. Post-mortem imaging is different to clinical imaging regarding both the appearance of pathology and the information required, but there is much to learn from many years of clinical research in the use of these techniques. Furthermore, it is possible that post-mortem imaging research could be used not only for investigating the cause of death but also as a model to conduct clinically relevant research. This article reviews challenges to the development of post-mortem imaging for trauma, identification and cardiorespiratory death, and how they may be influenced by current clinical thinking and practice.

A brief history of fatal child maltreatment and neglect

Child abuse encompasses four major forms of abuse: physical abuse, sexual abuse, psychological abuse, and neglect. The United States retains one of the worst records of child abuse in the industrialized world. It has also been determined that a large portion of these cases are missed and go undocumented in state and federal reporting agencies. In addition, disparate risk factors have been identified for physical abuse and neglect cases, but substance abuse has been found to be a significant factor in all forms of abuse. Fatal child maltreatment and neglect investigations require a multi-pronged and multidisciplinary approach requiring the coordination and information gathering from various agencies. A major difficulty in determining the accidental or non-accidental nature of these cases is that the account surrounding the events of the death of child is acquired from the caretaker. In this review, we outline common diagnostic characteristics and patterns of non-accidental injuries and neglect as a result of nutritional deprivation.

Skeletal survey normal variants, artefacts and commonly misinterpreted findings not to be confused with non-accidental injury

Radiology plays a key part in the investigation of non-accidental injury. Many normal variants and artefacts can simulate an abnormality associated with non-accidental injury. It is essential that radiologists reporting skeletal surveys in cases of suspected child abuse are aware of these. We present a pictorial essay to aid the reporting radiologist in the differentiation between normal variants or artefacts and true traumatic injury. We show plain film examples of potential pitfalls throughout the body.
