Utility of Immediate Postprocedural Cone Beam Computed Tomography in the Detection of Ischemic and Hemorrhagic Complications in Pediatric Neurointerventional Surgery.
Cone beam computed tomography (CBCT) imaging is used commonly in neurointerventional surgery for rapid intraprocedural assessment and planning of intracranial interventions. Our goal was to evaluate the ability of immediate postprocedural CBCT scan in assessing potential complications in pediatric patients. ⋯ Immediate postprocedural CBCT images were adequate to detect ventricular size/subarachnoid spaces changes and large volume hemorrhage compared with cCT scan in pediatric patients. However, there are limitations using immediate CBCT images to detect small volume hemorrhage and ischemic changes.

Pure pial arterial malformations (PAMs) are poorly understood owing to the limited number of reported cases. Because PAMs have been thought to have a benign natural history, they have generally been managed conservatively, unlike arteriovenous malformations or arteriovenous fistulas. In the present report, we have described a spontaneous subarachnoid hemorrhage from the rupture of a PAM at the cerebellomedullary junction. This hemorrhage was surgically treated using clip trapping.

Variant origin of the ophthalmic artery (OA) is uncommon. The majority of variant origins are from the middle meningeal artery and from the infraclinoid segment of the internal carotid artery. An OA arising from the accessory meningeal artery is an extremely rare vascular variation that has not been described previously in the English literature. ⋯ Being aware of variant origin of the OA from the accessory meningeal artery is very important for transarterial chemoembolization in the external carotid artery territory. Reconstructed images from magnetic resonance angiography are very useful to reveal the variant origin of the OA.

Candida auris is an emerging superbug which was recently discovered and has spread widely across the world. With a steady rise in incidence involving multisystems, this presents a unique challenge to caregivers. ⋯ C. auris appears to be an emerging superbug, which is hospital-acquired. All practitioners must be aware of its existence and presentation. Given the low incidence, high mortality, and no clear guidelines of management so far, formulation of any such strategies is complicated. Further studies and research are needed for this superbug.

Cytotoxic lesions of the corpus callosum will be present in a wide range of clinical conditions. The term "cytotoxic lesions of the corpus callosum" reflects our current understanding of the underlying pathophysiology of these lesions and does not necessarily imply confinement to the splenium. ⋯ Brain magnetic resonance imaging will be of pivotal value in the investigation. We report the case of a patient with obsessive-compulsive disorder who underwent bilateral deep brain stimulation of the nucleus accumbens and developed infection along the surgical path of both electrodes associated with a cytotoxic lesion in the splenium of corpus callosum.
