Internal carotid artery dissection after a roller coaster ride in a 4-year-old: case report and review of the literature

Headache and Dizziness after Roller Coaster Rides: A Case Series of 31 Patients

Previous literature on roller coaster injuries focuses on catastrophic injuries. We conducted a retrospective study of 31 adults with headache or dizziness after roller coaster rides. Twenty five of 31 (81%) patients presented with new or worsening headache, predominantly migraine (15/25, 60%), including 8/25 (32%) with chronic migraine. Of the chronic migraine patients, 4/8 (50%) already had the diagnosis and presented with an exacerbation. Five of the 25 (20%) were ultimately found to have a cerebrospinal fluid (CSF) leak. While persistent symptoms appear to be relatively rare, patients with chronic migraine and potential CSF leaks should consider skipping these attractions.

Cerebellar Stroke in a Young Adult Following an Amusement Park Ride

The incidence of stroke in young individuals has been showing an increasing trend. In such cases, atypical mechanisms of stroke should be considered. Here, we report a case of a 37-year-old healthy female who presented with complaints of right-sided ataxia and clumsiness that started after an amusement park ride where she was swung rapidly. Imaging revealed an infarct in the right cerebellar hemisphere. This case report highlights certain mechanisms that can cause a stroke in this situation, with special emphasis on recognition, timely medical management, public awareness of such risk factors, and the prevention of complications.

Internal Carotid Dissection as the Cause of Stroke in Childhood

Internal carotid artery (ICA) dissection is a cause of stroke, but it is often underdiagnosed in children. ICAs' risk factors and pathogenic mechanisms are poorly understood, and the treatment is still empirical. We report the case of a previously healthy 9-year-old girl who presented with involuntary hypertonic closure of the right hand associated with transient difficulty for both fine movements of the right arm and speech. She had a history of minor cervical trauma occurring 20 days prior to our observation without other associated risk factors. Magnetic resonance imaging and magnetic resonance angiography showed ischemic lesions due to the left ICA dissection. Treatment with both acetylsalicylic acid and levetiracetam allowed recanalization of the ICA associated with the resolution of clinical signs. Our clinical case suggests that the ICA dissection must be suspected early whenever a child manifests mild neurologic deficits after a cervical trauma, especially if they are associated with headache and/or cervical pain. Moreover, the management of ICA dissection must be improved.

Internal carotid artery dissection without intracranial infarct following a minor shoulder trauma: The second pediatric case and review of the literature

INTRODUCTION

Carotid artery dissections may occur in severe trauma such as motor vehicle accidents or may also develop due to minor trauma. We aimed to present a case with internal carotid artery dissection that referred to the pediatric neurology department due to speech impairment after minor shoulder trauma.

CASE

A previously healthy 10-year-old male patient was admitted to the pediatric emergency clinic due to headache, vomiting and speech impairment. In his story, we learned that he had bumped shoulder to shoulder with his friend about 6 h ago. He did not fall or hit his head. On his admission he could not speak and had right central facial paralysis. There was no infarct or diffusion limitation in MRI but MR angiography showed thinning in left internal carotid artery calibration. Fat-suppressed, non-contrast T1-weighted MRI showed that the left carotid artery had ring-shaped pathological signal changes. Low-molecular-weight heparin therapy was initiated with the diagnosis of carotid artery dissection (CAD). No hemiparesis or hemiplejia occurred in the follow-up of the patient. Within a few days, his speech improved. At the end of the first month, facial paralysis completely recovered.

CONCLUSION

In carotid artery dissections, prodromal symptoms such as transient ischemic attack, like in our patient, are rarely present in children. For good long term outcomes, it is very important to suspect, diagnose and initiate appropriate treatment in a rapid manner in carotid artery dissection before severe neurological findings such as acute ischemic stroke develops.

Middle Cerebral Artery Stroke as Amusement Park Injury: Case Report and Review of the Literature

Strokes as amusement park injuries are rare, but have been reported in the literature. Only about 20 cases of cerebrovascular accidents after amusement park visits have been described. We report a healthy 12-year-old boy who presented with facial droop, slurred speech, and inability to use his right arm after riding roller coasters at a local amusement park. He was evaluated and found to have a left middle cerebral artery (MCA) infarction. The patient was treated with anticoagulants and has recovered with no major residual symptoms. It is likely that his neurological symptoms occurred due to the high head accelerations experienced on the roller coasters, which are more detrimental to children due to immature cervical spine development and muscle strength. Early diagnosis of dissection and stroke results in a favorable prognosis. Providers and parents should be aware of the potential risk of roller coasters and act quickly on neurologic changes in children that have recently been to an amusement park.
