Summary
A presyrinx state, a precursor to syringomyelia, was successfully treated in a 66-year-old woman. Surgical intervention resolved symptoms and prevented further progression of the spinal cord condition.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Adhesive arachnoiditis can lead to serious spinal cord complications.
- The presyrinx state is an early, reversible stage preceding syringomyelia.
Observation:
- A 66-year-old woman presented with gait disturbance and sensory deficits due to adhesive arachnoiditis.
- Thoracic spine MRI revealed cord swelling, intramedullary signal changes, and spinal canal compression from an arachnoid cyst.
Findings:
- Surgical detachment of arachnoid adhesions and CSF flow restoration improved neurological deficits.
- Postoperative MRI confirmed reduced thoracic cord swelling, normalized signal intensity, and decreased cyst size.
Implications:
- Early diagnosis and surgical treatment of the presyrinx state can prevent the development of syringomyelia.
- This case highlights the importance of recognizing and intervening in the presyrinx state for favorable outcomes.

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,...
01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
