Middle meningeal artery aneurysm associated with meningioma is extremely rare, and only two cases have previously been reported. In our case, a 72-year-old woman with convexity meningioma underwent preoperative cerebral angiography, which revealed a flow-related aneurysm on the middle meningeal artery. Embolization of the aneurysm was performed with N-butycyanoacrylate glue, and complete obliteration was confirmed under craniotomy. In order to eliminate the risk of preoperative rupture resulting in intracranial hemorrhage, endovascular embolization with liquid glue is safe and effective for this kind of aneurysm.

BACKGROUND Chiari malformation type 1 occurs when the cerebellar tonsils are pushed into the spinal canal, which can result in syringomyelia. This retrospective study from a single center evaluated outcomes in 89 patients with Chiari malformation type-I (CM-I) and syringomyelia treated with an arachnoid-preserving technique between 2016 and 2023. MATERIAL AND METHODS A retrospective analysis was conducted at a tertiary referral center, involving 88 adult patients and 1 adolescent patient aged 14 to 61 years, with diagnosis by MRI and treated for CM-I with syringomyelia between 2016 and 2023, using the arachnoid-preserving technique.

Rationale: Ependymomas are commonly prevalent intramedullary neoplasms in adults, with hardly any cases of exophytic extramedullary ependymoma being reported. Meningiomas, on the contrary, are one of the most common intradural extramedullary (IDEM) tumors. However, the occurrence of both IDEM tumors simultaneously is extremely rare.

Background: Hemophagocytic lymphohistiocytosis (HLH), is characterized by systemic uncontrolled inflammation resulting from immune dysregulation secondary to various triggers, including genetics, infections, autoimmune diseases, and malignancies. Macrophage activation syndrome (MAS) is an immune dysregulation phenomenon, in which an underlying rheumatological disease is present. We report a rare, interesting case of a middle-aged female, with a systemic lupus erythematosus (SLE) flare complicated by macrophage activation syndrome (MAS), in which tuberculous meningitis (TBM) was the identified trigger.

Background: Seasonal influenza illness and acute respiratory infections can impose a substantial economic burden in low- and middle-income countries (LMICs). We assessed the cost of influenza illness and acute respiratory infections across household income strata.
Methods: We conducted a secondary analysis of data from a prior systematic review of costs of influenza and other respiratory illnesses in LMICs and contacted authors to obtain data on cost of illness (COI) for laboratory-confirmed influenza-like illness and acute respiratory infection.

To investigate the value of preoperative MRI features and ADC histogram analysis for evaluating tumor-infiltrating CD8+ T cells in meningiomas. In this single-center cross-sectional study, we conducted a retrospective analysis of clinical, imaging, and pathological data from 84 patients with meningioma and performed immunohistochemical staining to quantitatively evaluate CD8+ T cells. Using X-Tile software, we divided the patients into high-and low-CD8+ T cells groups based on cut-off values.
