AbstractThe objective of this study was to describe the clinicodemographic profiles, management, and outcomes of brain stem lesions in 53 pediatric patients with brain stem lesions. Most of the patients were male, 6 to 10 years of age (8.66 ± 4.69). Out of 53 patients, there were 77.36% brain stem gliomas, 11.32% tuberculomas, 5.66% abscesses, 3.77% cavernomas, and 1.89% schwannomas. With advancement in neuroimaging (e.g., tractography), intraoperative technology (e.g., ultrasound, neurophysiological monitoring, and magnetic resonance imaging), and safe and precise incision for particular lesions, majority of brain stem lesions had improved outcomes (67.92%) with significant reduction in morbidity and mortality (11.32%).

Abstract A major limitation to the effective treatment of intrinsic mass lesions of the brain stem has been the inability to clearly define the pathological anatomy radiographically. The improved soft tissue resolution offered by magnetic resonance imaging, as compared with axial computed tomography, now makes it possible not only to accurately distinguish anatomical relationships, but also to predict the pathological nature of the lesion. Accordingly, we have been encouraged to pursue a more aggressive approach to intrinsic lesions of the brain stem that appear well circumscribed on magnetic resonance imaging scan. The object of this paper is to report the successfuly treatment of four intrinsic lesions of the brain stem and to present an overview of the relevant published experience.

Purpose The aim of this study was to assess the novel advanced magnetic resonance imaging findings of acute stage cortical laminar necrosis developing after complicated cardiovascular or abdominal surgery. Materials and methods This institutional review board-approved study included patients with postoperative stroke due to cortical laminar necrosis imaged with magnetic resonance in the acute stage. Brain magnetic resonance imaging examinations were obtained on a 3T magnetic resonance scanner within 48 hours of the neurological symptoms, including diffusion-weighted images (b value, 1000 s/mm2) and arterial spin labelling using a pseudo-continuous arterial spin labelling method in four patients. Conventional and advanced magnetic resonance images were analysed to assess the imaging features in acute stage cortical laminar necrosis. Results The final population consisted of 14 patients (seven men and seven women, mean age 61 years, range 32–79 years) diagnosed with stroke and acute phase cortical laminar necrosis. All the patients presented with cortical lesions showing restricted diffusion on diffusion-weighted images and hypointensity on the apparent diffusion coefficient map. Cortical hyperintensity on T2-weighted or fluid-attenuated inversion recovery images was found in three (21%) and six (43%) patients, respectively. Reduced perfusion was noted in three out of four patients imaged with arterial spin labelling, while in one case no corresponding perfusion abnormality was noted on the arterial spin labelling maps. Arterial spin labelling abnormalities were much more extensive than diffusion restriction in two patients, and they were associated with a poor outcome. Conclusion Cortical hyperintense abnormalities on diffusion-weighted imaging may be the only sign of developing cortical laminar necrosis injury. The acquisition of arterial spin labelling helps to identify perfusion alterations and the extension of the ischaemic injury.

Persistent Headache

A 31-years-old patient, pregnant at 32 weeks of gestation presented to our triage unit with complaint of gradually progressive persistent headache that started 1 day earlier and was unresponsive to all analgesics. Her history was insignificant for any major medical or surgical events and the pregnancy course was smooth as well. Her lab results and obstetric ultrasound were reassuring. During magnetic resonance imaging examination, the patient suddenly deteriorated after giving her an inhalational anaesthesia for sedation. She became unconscious. She was intubated, mechanically ventilated, and put-on cardiovascular support. Brain imaging then revealed Brain Stem (BS) herniation and diffuse brain oedema. She was announced dead with intrauterine foetal death. A late diagnosis of cerebral venous thrombosis was established. This caused BS herniation through increased intracranial pressure, which was iatrogenically augmented by administering inhalation anaesthesia. Keywords: cerebral vein; thrombosi; thrombophilia; pregnancy; headache; magnetic resonance imaging; brain stem herniation.
