Article Synopsis
- A 50-year-old woman was successfully diagnosed with idiopathic cerebrospinal fluid rhinorrhea using contrast-enhanced fluid-attenuated inversion recovery (FLAIR) imaging techniques.
- Pre- and postcontrast FLAIR subtraction images revealed a protrusion in the right olfactory cleft canal, demonstrating the effectiveness of this imaging method alongside traditional CT and MR cisternography.
- The confirmed diagnosis led to an endoscopic nasal surgery to repair the fistula, resulting in a positive clinical outcome.
Background: Aplastic or twig-like middle cerebral artery (Ap/T-MCA) is a rare vascular anomaly that can cause hemorrhagic and ischemic stroke. Ap/T-MCA can induce aneurysms due to the fragility of the vessel wall, consequently leading to subarachnoid hemorrhage. Herein, we report a case of Ap/T-MCA with subarachnoid hemorrhage without an aneurysm.

However, there are few detailed reports of pathological analyses of mitochondria and the factors that cause acute kidney injury (AKI) as a result of nephrotoxicity. In this study, we investigated mitochondrial damage in the proximal tubule in AKI mice at 6, 12, and 24 h after administration of diclofenac.

- Mast cells produce cytokines and chemokines that are important in disease processes, and they contain high levels of the ganglioside GM3, which is essential for their function.
- In a study, mast cells lacking GM3 synthase (GM3S) exhibited changes that made them overly reactive to stimuli, leading to increased inflammation without affecting their growth.
- The absence of GM3S resulted in decreased membrane integrity and heightened skin allergic reactions, while restoring GM3 levels improved membrane stability and helped reduce excessive signaling linked to allergic responses.
A 78-year-old man underwent a tracheostomy after embolization for a dural arteriovenous fistula. Seventy days after tracheostomy, arterial bleeding appeared through the tracheal stoma. The bleeding stopped spontaneously.
