Spinal subdural hygroma

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Spinal subdural hygroma is an uncommon condition.
• Its pathophysiology and prevalence remain largely unknown.
• Often associated with trauma, iatrogenic causes, or intracranial hypotension.

Purpose of the Study:

• To review current knowledge on spinal subdural hygroma.
• To cover aspects from embryology to treatment.
• To highlight diagnostic and therapeutic challenges.

Main Methods:

• Systematic literature review using sensitive search strategies.
• Analysis of relevant articles on spinal subdural hygroma.
• Focus on radiological detection and treatment modalities.

Main Results:

• Magnetic Resonance (MR) imaging is the gold standard for diagnosis.
• Conservative treatment is typically successful; surgery is rare.
• Addressing the underlying cause is crucial for management.

Conclusions:

• Spinal subdural hygroma is underdiagnosed due to rarity and association with other pathologies.
• Further research is needed to understand its prevalence and pathophysiology.
• High-resolution imaging is essential for accurate diagnosis.
