RESUMO
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.
RESUMO
BACKGROUND: Non-typhoid Salmonella (NTS) is an important cause of bacterial meningitis in newborn and infants in developing countries, but rarely in industrialized ones. We describe an unusual presentation of bacterial meningitis in an infant, focusing on his diagnostic and therapeutic management. CASE REPORT: An Italian two-month old male presented high fever and diarrhea with blood, associated with irritability. Inflammatory markers were high, cerebrospinal fluid analysis was compatible with bacterial meningitides but microbiological investigations were negative. Salmonella enteritidis was isolated from blood. Cerebral ultrasound and MRI showed periencephalic collection of purulent material. Specific antibiotic therapy with cefotaxime was initiated with improvement of clinical conditions and blood tests. Brain MRI follow up improved progressively. CONCLUSIONS: Most of pediatric patients with NTS infection develop self-limited gastroenteritis, but in 3-8% of the cases complications such as bacteremia and meningitis may occur, especially in weak patients. Cerebral imaging can be useful to identify neurological findings. Although there is no standardized treatment for this condition, specific antibiotic therapy for at least four weeks is recommended. Neuroimaging follow up is required due to high risk of relapse.
