AI Article Synopsis
- The study aims to demonstrate that the pain experienced during migraines is not caused by the expansion of dural meningeal arteries.
- Current theories attribute migraine pain to changes in the trigeminovascular system, including large blood vessels and their neural connections.
- Anatomical evidence shows that dural meningeal arteries are firmly encased in the dura mater and positioned in grooves of the calvarium, preventing them from dilating during a migraine episode.
Article Abstract
Objective: To show that migraine pain is not related to dilatation of the dural meningeal arteries.
Background: The origin of the pain in migraine has not yet been adequately explained and remains the subject of vigorous debate. Current theories implicate changes in the trigeminovascular system, which is defined as comprising the large intracranial vessels, and in particular, the dural meningeal vessels, the dura mater, and their neural connections.
Methods: The anatomical relationships of the dural meningeal arteries to the dura mater and the inner surface of the calvarium are described.
Results: The dural meningeal arteries lie in grooves in the inner table of the calvarium, are encased in the unyielding fibrous dura mater, and are consequently unable to dilate.
Conclusion: The pain of migraine is not related to dilatation of the dural meningeal arteries.

Cleveland Clinic Head and Neck Institute, Cleveland, Ohio.
Background: Endoscopic sinus surgery (ESS) is a minimally invasive procedure indicated for medically refractory chronic sinusitis (CRS). As with any surgical procedure, there are potential risks and complications.
Objective: The purpose of this study is to report skull base, orbital, and hemorrhagic-associated complication rates following ESS.
Endovascular Treatment for Tentorial Dural Arteriovenous Fistulas: A Retrospective Single-Center Study.
AJNR Am J Neuroradiol
January 2025
Department of Neurovascular Center, Changhai Hospital, Naval Medical University, Shanghai, China.
Background And Purpose: Current evidence suggests that tentorial dural arteriovenous fistulas with endovascular treatment offer a high rate of occlusion and reduced procedural risks. Here we report the clinical and angiographic outcomes in patients with tentorial dural arteriovenous fistulas who underwent endovascular treatment as first-line treatment.
Materials And Methods: A retrospective analysis was conducted on 83 patients with tentorial dural arteriovenous fistulas treated at our center from April 2009 to November 2023 using endovascular treatment.
Dural perforation and life-threatening central nervous system complications associated with septic arthritis of the lumbar facet joint: illustrative case.

Department of Orthopedic Surgery, Iwate Medical University, Shiwa-gun, Iwate Prefecture, Japan.
Background: Septic arthritis of the lumbar facet joint (SALFJ) is a rare condition that can lead to serious complications. The authors present an uncommon case in which SALFJ resulted in bacterial meningitis (BM) with hydrocephalus and pyogenic ventriculitis, causing a disturbance of consciousness. Reports describing perforation of the dura mater by an epidural abscess are rare, and the present case offers valuable insights into the management of complex and severe complications arising from SALFJ.

January 2025
Department of Ophthalmology, University of California, Los Angeles, California, United States.
Purpose: The optic nerve (ON) is mechanically perturbed by eye movements that shift cerebrospinal fluid (CSF) within its surrounding dural sheath. This study compared changes in ON length and CSF volume within the intraorbital ON sheath caused by eye movements in healthy subjects and patients with optic neuropathies.
Methods: Twenty-one healthy controls were compared with 11 patients having primary open angle glaucoma (POAG) at normal intraocular pressure (IOP), and 11 with chronic non-arteritic anterior ischemic optic neuropathy (NA-AION).
Paediatric primary intraosseous meningioma of the calvarium.

Radiodiagnosis, AIIMS Nagpur, Nagpur, Maharashtra, India.
A boy in his middle childhood presented with a gradually enlarging, mildly tender swelling in the left frontal region, noticed after minor trauma. Skull radiograph and non-enhanced CT revealed a diffuse sclerotic lesion involving the left frontal bone and overlying subcutaneous soft tissue, suggestive of an intraosseous haemangioma. Contrast-enhanced MRI showed an expansile, hypointense lesion in the frontal bone on the left side with enhancing extraosseous components and a small extra-axial cyst.
