Traumatic subarachnoid hemorrhage and extracranial vertebral artery injury: a case report and review of the literature

The case is presented of a 19-year-old man who was assaulted and died shortly afterward from a large traumatic basal subarachnoid hemorrhage (TBSAH) that arose from rupture of the left vertebral artery, proximal to the point at which the artery penetrated the dura. The literature regarding TBSAH and vertebral artery rupture is reviewed, and a number of points are highlighted: patients with TBSAH may remain conscious for a period of hours after injury, subcutaneous or muscular bruising may be contralateral to the ruptured vessel, fractures of the transverse processes of the cervical vertebrae and significant pathology of the vertebral artery are not typically associated with TBSAH, and rupture of the vertebral artery may be intracranial, junctional, or extracranial.     

Cerebral traumatism with a playground rocking toy mimicking shaken baby syndrome

Shaken baby syndrome (SBS), one of the most deadly and devastating forms of child abuse, is caused by violent shaking. The combination of subdural hematoma, retinal hemorrhage, brain swelling, and diffuse axonal injury is highly typical of this syndrome and faced with these autopsy findings, induced traumatic lesions are strongly considered. However, it is known that motor-vehicle accidents and falls from great height can also produce this pattern of injury. Nevertheless, stories of arms fall, couch fall, or bumped head while the baby is being carried are generally considered incompatible with SBS. We here report a case of a 2-year-old boy presenting with all the classic autopsy findings of SBS from a playground rocking toy shaken by an older child.     

Traumatic dissection of the vertebral artery in a toddler following a short fall

Spontaneous subarachnoid haemorrhage (SAH) in children is uncommon, but is sometimes seen after rupture of aneurysms, and in different disorders. Traumatic SAH is common after serious accidental head injury, but is also reported after child abuse with vigorous shaking. To avoid unnecessary accusations of innocent care givers, it is important not to misinterpret the findings as abusive head trauma in small children with SAH. In the presented case, a nearly two-year-old girl was brought to the hospital after a fall witnessed by her father. The girl was unconscious, with elevated intracranial pressure, SAH and bilateral retinal haemorrhage (RH). She was pronounced dead after 9h. Premortem angiography revealed a dissection of the right vertebral artery, and postmortem examination revealed a traumatic lesion deep in the neck, at the base of the skull. Cerebral edema, in combination with SAH and RH, is highly suggestive of abusive head trauma. However, no external lesions, no skeletal lesions, especially no long bone metaphyseal lesions, or subdural haematomas occurring at the same time as SAH, were found. There was no report of previous child abuse in the family. Based on the radiological and postmortem findings, we believe that an accidental fall caused a blunt force trauma with a subsequent dissection of the right vertebral artery. To our knowledge, accidental tear of one of the vertebral arteries, leading to SAH in a toddler, has previously not been described. Child abuse is an important exclusion diagnosis with serious legal implications.     

Injury of the vertebral artery in suicidal hanging

The vertebral artery was investigated in suicidal hanging for specific forensic, but also general traumatological reasons. The objective was to establish the extent to which the vertebral artery in its relatively protected position is injured at all and if so, in what form. For this purpose, cervical spine preparations with the posterior space of the skull were fixed in formalin and detached in the sagittal plane in 36 unselected cases of suicidal hanging after angiographic visualization of the vertebral artery. Afterwards, both vertebral arteries were visualized, and vascular injuries were compared with injuries of the soft tissues of the neck, of the cervical spine, and of the external types of hanging. The vertebral artery was shown to be injured quite frequently (rupture, intimal tear, sub-intimal hemorrhage), namely in one quarter of all cases, and indeed in more than half taking into account the perivascular bleeding. In this way, frequencies were found which were far in excess of those of the common carotid artery. The different mechanical behavior of these two paired neck arteries in traction are dealt with and the form of injury explained.     

Fatal lung hemorrhage in complex pulmonary angiodysplasia in a case of mongolism

A case of sudden and unexpected death of a boy with Down-Syndrome is reported. Death was due to acute excessive haemorrhage from the lungs. There were no cardiac anomalies. Histology revealed in addition to mediahyperplasia, intimaproliferation and occlusions, multiple foci of anomalous ectatic blood vessels predominantly in the lungs, some of which ruptured and bled into adjacent airways. Evidence of previous less severe bleeding episodes was present. Further investigation showed a familial occurrence of the blood vessel anomaly.

Shaken baby syndrome and the death of Matthew Eappen: a forensic pathologist's response

Subdural hemorrhage, retinal hemorrhage, and cerebral edema have been considered diagnostic for a "shaken infant" since the syndrome was described almost 30 years ago. However, the specificity of these findings has been disputed by defense witnesses in recent U.S. criminal prosecutions. This review examines the scientific basis for the shaken baby syndrome.     

Morphometric studies of the vertebral artery in infants and small children

The internal circumference of the vertebral artery and the cross-sectional area of its tunica media were measured planimetrically at three different topographical sites in 48 cases of sudden infant death syndrome (SIDS) and 18 reference cases. Based on preliminary determination of the error of measurement, both groups studied showed significant differences between sides. As the degree of differences is often marked, impressive haemodynamic consequences can be expected. The findings are discussed with regard to SIDS.

Fatal subarachnoid hemorrhage during sexual anal self-stimulation in a female: a case report

Sudden death after sexual activity is a well-known entity, but it is rare in females. Herein we present a case of fatal, massive subarachnoid hemorrhage from a ruptured berry-shaped aneurysm, during sexual anal self-stimulation. A 39-year-old woman was found dead on a couch, with the wooden handle of a spring twirl whisk inserted inside her anus and rectum as a dildo-like object. External examination was unremarkable with no signs of injuries. Intracranial examination showed a massive subarachnoid hemorrhage, up to 6 mm in thickness, especially around the brainstem and the inferior side of the brain. After removing the blood clots, the saccular aneurysm was found at the site of the bifurcation of the left internal carotid. In this case study, we underline the utility of forensic autopsy, as well as death scene investigation, in reconstructing the mechanism of death, as well as the dynamics of the event.     

Carotid and vertebral artery circulation in forearm choke holds in Doppler sonography

By means of continuous wave doppler the effect of two choke holds (Carotid sleeper, Nami-juji-jime) on the carotid and vertebral arteries was investigated. For both choke holds, which are characterized by pressure on lateral parts of the neck, we found an obstruction up to a complete stop of flow. The degree of obstruction depended on the direction of force. The vertebral artery can be compressed between the subclavian artery and the foramina transversaria, therefore it was most effective to press on the lower neck. Tensing the neck muscles can reduce the effect of choking.     

Supernumerary mammillary bodies--findings in a case of fetal alcohol syndrome

A case of fetal alcohol syndrome is described, in which supernumerary corpora mamillaria were found and in which the exterior embryonal-cell granular layer of the cerebellum showed superficial indentations.     

Vertebral artery rupture in a sudden death case after mild trauma

We report a case of subarachnoid hemorrhage at the skull base with possible rupture of a vertebral artery, and we present a new method to investigate rupture of this artery. In this method, the brain stem and cerebrum are divided with ligation of the internal carotid artery and basilar artery, and milk is injected from the original part of the vessel to find the rupture. We show that this method is particularly useful for cases of subarachnoid hemorrhage at the skull base in which there may be rupture of a vertebral artery.     

Sudden and unexpected death of a 6-month-old baby with silent heart failure due to anomalous origin of the left coronary artery from the pulmonary artery.

A 6-month-old girl died suddenly without any previous symptoms of heart failure. Autopsy examination showed cardiomegaly (97 g) with a severely fibrotized myocardium. The left coronary artery was originating from the pulmonary artery. Histologically, the myocardium showed myocardial infarcts of different ages, as well as grossly thickened arterial branches due to increased flow in left-right shunt. We suggest that rare anomalies of the coronary arteries should be considered in the autopsies of suspected sudden infant death syndrome cases.
