Acute intracranial infections of the central nervous system and skull base are uncommon but time sensitive diagnoses that may present to the emergency department. As symptoms are frequently nonspecific or lack typical features of an infectious process, a high index of suspicion is required to confidently make the diagnosis, and imaging may not only serve as the first clue to an intracranial infection, but is often necessary to completely characterize the disease process and exclude any confounding conditions. Although computed tomography is typically the initial imaging modality for many of these patients, magnetic resonance imaging offers greater sensitivity and specificity in diagnosing intracranial infections, characterizing the full extent of infection, and identifying potential complications. The aim of this article is to serve as a review of the typical and most important imaging manifestations of these infections that can be encountered in the emergent setting.

Polyarteritis nodosa with life-threatening intracranial aneurysms in a child, and treatment with infliximab.

Turk J Pediatr

Department of Pediatric Rheumatology, Umraniye Training and Research Hospital, University of Health Sciences, İstanbul, Türkiye.

Background: Polyarteritis nodosa (PAN) is a rare and serious form of systemic necrotizing vasculitis that predominantly affects medium and small-sized arteries, with central nervous system involvement being particularly uncommon. Treatment strategies are tailored according to the extent and severity of the disease. While conventional therapy includes glucocorticoids and conventional disease-modifying-rheumatic drugs (cDMARDs), biologic agents may be critical for severe and refractory cases.

Context: This study aimed to investigate the characteristics, diagnosis, and management of tuberculous longitudinally extensive transverse myelitis (TB-LETM), a rare manifestation of tuberculosis.

Findings: We analyzed two rare cases of TB-LETM and discussed their clinical manifestations and imaging findings in the context of the relevant literature. Patient 1, a 23-year-old female, presented with quadriplegia and dysuria, and spinal magnetic resonance imaging (MRI) revealed lesions extending from C1 to T3.

Background: Intracranial aneurysms (IAs) are a significant clinical concern, with detection rates increasing due to advances in imaging technologies. However, precise mechanisms underlying their pathophysiology remain incompletely understood. Recent evidence suggests a pivotal role of oral microbiota dysbiosis, particularly periodontal pathogens, in systemic inflammation that may contribute to IA development and rupture.

Objective: This randomized controlled trial (RCT) aimed to compare the short-, mid-, and long-term outcomes in patients with malignant intracranial hypertension undergoing either decompressive craniectomy (DC) or hinge craniotomy (HC).

Methods: In this prospective RCT, 38 patients diagnosed with malignant intracranial hypertension due to ischemic infarction, traumatic brain injury, or non-lesional spontaneous intracerebral hemorrhage, who required cranial decompression, were randomly allocated to the DC and HC groups.

Results: The need for reoperation, particularly cranioplasty, in the DC group was significantly different from that in the HC group.

Introduction: Aneurysmatic subarachnoid hemorrhages (aSAH) are life-threatening events with high mortality and morbidity. Hydrocephalus is a common complication, initially managed with an external ventricular drain (EVD). Persistent hydrocephalus often requires ventriculoperitoneal shunt (VPS) placement to relieve intracranial pressure and prevent further neurological damage.
