Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
Sinusoidal Sources01:18

Sinusoidal Sources

Direct current (DC) refers to an electric current that flows in a single direction, maintaining a constant polarity. This is in contrast to alternating current (AC), which periodically changes its direction and magnitude. AC forms the backbone of modern electricity transmission and distribution systems due to its efficient long-distance transmission capabilities.
In homes, the power supplies use sinusoidal sources to provide electricity. These sources generate a voltage that varies sinusoidally...
Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
Brain Abscess l: Introduction01:26

Brain 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,...

Summary

A foreign body was found in a patient's transverse sinus, potentially entering through the anterior fontanelle and superior sagittal sinus. This unusual case highlights a rare pathway for intracranial foreign bodies.

Area of Science:

  • Neurosurgery
  • Radiology
  • Emergency Medicine

Background:

  • A 35-year-old man presented with a left eyelid laceration and an incidental skull foreign body.
  • Initial examination revealed right hemianopsia in the left eye without other neurological deficits or headache.

Observation:

  • Computed tomography (CT) identified a foreign body within the left transverse sinus.
  • No other intracranial abnormalities were detected on CT scan.

Findings:

  • The pathway of the foreign body into the transverse sinus was unclear.
  • A possible route suggested is penetration through the anterior fontanelle, traversing the superior sagittal sinus.

Implications:

  • This case presents a rare instance of a foreign body in the transverse sinus with an ambiguous entry point.
