1/28. Pediatric spine and spinal cord injury after inflicted trauma. Pediatric spine and spinal cord injury are rare sequelae of intentional trauma. They may easily be overlooked, however, and probably represent an underreported phenomenon. Recent autopsy data analyzed in conjunction with prior case series indicate that injury to the upper cervical spine and brainstem may significantly contribute to the major morbidity, mortality, and neuropathology in shaken infants. The findings in the previous case report illustrate several important points regarding spine and spinal cord injury after intentional trauma. First, the very young are susceptible to severe, higher cervical injury of both spine and spinal cord. Second, spine and spinal cord injury were initially overlooked because of masked neurologic findings with the concomitant head injury and multiple other systemic injuries. Finally, the child's outcome with significant cognitive delay because of global brain injury in conjunction with the focal high cervical cord injury may support the hypothesis that hypoxic damage could have occurred secondary to brainstem and high cervical cord injury. At the authors' institution, a detailed history and vigilant physical examination are stressed. When the mechanism of injury reported in the history is incongruous with the physical or initial radiographic findings and intentional trauma is suspected, a full skeletal survey, ophthalmologic evaluation, and social evaluation is undertaken. MRI and CT scanning are individualized according to the clinical assessment. ( info) |
2/28. Massive subdural haematomas in Menkes disease mimicking shaken baby syndrome. INTRODUCTION: Menkes disease is an X-linked inherited disorder of intestinal copper absorption resulting in copper deficiency. Cardinal features include hair abnormalities, facial dysmorphism, severe neurological impairment, hypothermia, arterial anomalies, bone abnormalities and a fatal outcome. CASE REPORT: We present a case of Menkes disease complicated by progressive macrocephaly following the development of massive subdural haematomas. These lesions associated with femoral metaphyseal spurs could be confused with nonaccidental injury such as that seen in the shaken baby syndrome. DISCUSSION: This case emphasises that Menkes disease, like glutaric aciduria type 1, should be included in the differential diagnosis of unexplained subdural haematomas and neurological deficits in infants.

3/28. Marked calvarial thickening and dural changes following chronic ventricular shunting for shaken baby syndrome. We report the case of a 23-year-old woman who was abused at the age of 5 months. She suffered from complications frequently associated with shaken baby syndrome, such as hydrocephalus secondary to subarachnoid hemorrhage. The patient underwent a procedure to place a ventriculoperitoneal shunt 3 weeks after her presentation with signs of abuse. The ventricular shunt remained in place throughout her life, and the patient received multiple revisions. She also was noted to have a markedly thickened calvarium on both radiographs and computed tomographic scan at 6 years old. She died following an episode of grand mal status epilepticus. An autopsy was performed and her skull was found to be thickened circumferentially. Histologic examination revealed increased cancellous space with normal trabecular bone. It is hypothesized that intracranial hypotension resulting from chronic ventricular shunting lead to her thickened calvarium, a condition previously reported as hyperostosis cranii ex vacuo. Dural changes seen microscopically corroborate this hypothesis. ( info) |
4/28. Cerebral atrophy following shaken impact syndrome and other non-accidental head injury (NAHI). PURPOSE OF THE STUDY: To determine the frequency of cerebral atrophy and microcephaly in a group of children with sequential MRI brain scans after surviving a non-accidental head injury (n = 16). methods: Serial head circumference measurements (OFC) were extracted and plotted on standard growth charts for each child retrospectively to determine the frequency of secondary microcephaly. Cerebral atrophy was diagnosed and quantified by measurement of the ventricular/cortical ratio on coronal images of the sequential scans. RESULTS: Acquired microcephaly was found in 15 children (93.8%) over a median follow-up period of 67.93 weeks. There was a significant reduction in the median Z-score for the OFC at the most recent follow-up when compared with that at presentation (p < 0.001, Wilcoxon Signed Rank Test). Cerebral atrophy was found to be the cause of the microcephaly in eight of the 15 children and was evident as early as 9 days after presentation. CONCLUSION: A large proportion of the cohort (93.8%) develops acquired microcephaly after an inflicted head injury and cerebral atrophy is responsible in half of these cases. ( info) |
| We present the characteristic CT and MRI findings of a 2-month-old girl with shaken baby syndrome. diffusion-weighted MR imaging performed 8 days after the insult established the presence of injury to the white matter in the corpus callosum and subcortical white matter in the temporo-occipito-parietal region. diffusion-weighted MR imaging is valuable in the diagnostic work-up of suspected shaken baby syndrome, as injury to the white matter can be demonstrated days after the injury.

| shaken baby syndrome is a significant cause of infant morbidity and mortality and is widely recognized in the medical literature. Classic signs include retinal hemorrhage, subdural or subarachnoid hemorrhage, and associated fractures. Most victims are younger than 6 months old and have been affected by violent shaking with rapid angular deceleration and possible terminal impact. This article summarizes issues related to clinical presentation, diagnosis, risk factors, and interventions for healthcare professionals. ( info) |
7/28. Shaking infant trauma induced by misuse of a baby chair. A 2 month old infant presented with bilateral subdural haemorrhages and bilateral subhyaloid haemorrhage. The parent admitted to forceful bouncing of the child in a baby rocker. Experiments showed that violent rocking in the chair could produce extreme alternating acceleration/deceleration forces in excess of those induced by shaking alone. Such handling could not be interpreted as accidental mismanagement and the abusive nature of the process was graphically shown in video recordings of the experiment. Prosecution resulted in a conviction for cruelty, and a suspended sentence. ( info) |
| shaken baby syndrome is a constellation of injuries resulting from the intentional shaking type movement of a child who is usually younger than 3-years-old. This rapid acceleration-deceleration movement of the head is responsible for lesions attributed to shearing forces placed on the vitreoretinal structures and meningeal vessels across the dura. The ophthalmic findings include intraocular hemorrhages, perimacular retinal folds, and peripheral retinoschisis in the presence of intracranial injuries such as subdural hematomas without obvious external signs of head trauma. We describe a case of late development of an epiretinal membrane in a child with a history of shaken baby syndrome and propose a differential diagnosis list for epiretinal membrane formation in the pediatric age group.

9/28. Cortical hypoxic-ischemic brain damage in shaken-baby (shaken impact) syndrome: value of diffusion-weighted MRI. Shaken-baby syndrome (SBS) is a type of child abuse caused by violent shaking of an infant, with or without impact, and characterized by subdural hematomas, retinal hemorrhages, and occult bone fractures. Parenchymal brain lesions in SBS may be missed or underestimated on CT scans, but can be detected at an earlier stage with diffusion-weighted MRI (DW-MRI) as areas of restricted diffusion. We demonstrate the value of DW-MRI in a 2-month-old baby boy with suspected SBS. The pattern of diffusion abnormalities indicates that the neuropathology of parenchymal lesions in SBS is due to hypoxic-ischemic brain injuries, and not to diffuse axonal injury. ( info) |
10/28. Depressed skull fractures: a pattern of abusive head injury in three older children. OBJECTIVE: To describe a pattern of abusive head injury in a series of children older than 4 years of age. methods: A hospital chart review of abused children with skull fractures from 1999 to 2001 was carried out. The clinical features, social background, and subsequent outcome and management are described. RESULTS: An 11-year-old girl and a pair of brothers of ages 7 and 9 were identified. The girl was attacked with a hammer during sleep by her stepmother, who committed suicide shortly afterwards. After craniotomy and intensive care, the child survived her multiple depressed fractures, intracranial bleeding, and brain contusion. Two brothers from a second family were attacked from behind with a hammer by their biological father, who was subsequently found to have undiagnosed schizophrenia. A depressed occipital fracture, without intracranial injury, was found in each child. The elder brother also had metacarpal fractures. Both children recovered without surgical intervention. CONCLUSION: A pattern of abusive head injury was described in older children with depressed skull fractures from blunt injury. The abusing parents were seriously mentally disturbed, and the abusive acts closely resembled child homicide. ( info) |
