Summary
Sinus pericranii, a rare venous anomaly, involves unusual connections between cranial and scalp veins. This case details a unique bilateral frontal presentation in a child, with veins coursing unusually long distances.
Area of Science:
- Vascular Neurology
- Pediatric Neurosurgery
- Medical Imaging
Background:
- Sinus pericranii is a rare congenital venous malformation.
- It establishes an abnormal connection between the intracranial dural sinuses and the extracranial venous system.
- These anomalies can pose diagnostic and therapeutic challenges.
Observation:
- A 12-year-old boy presented with bilateral frontal sinus pericranii.
- Associated symptoms included lacrimation.
- Imaging revealed an atypical venous course connecting the superior sagittal sinus to the left superior ophthalmic vein.
Findings:
- The connecting veins exhibited an unusually long intratabular course.
- This anatomical variation differs significantly from typical short bridging veins.
- This specific presentation has not been previously documented in medical literature.
Implications:
- Highlights the diverse anatomical variations of sinus pericranii.
- Emphasizes the importance of detailed imaging in diagnosing venous anomalies.
- Contributes to the understanding of rare cerebrovascular malformations in pediatric patients.

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
