Duropathies as Unifying Concept-Part Two: A Narrative Overview of Clinical and Neuroradiological Features

Area of Science:

• Neurology
• Neurosurgery
• Radiology

Background:

• Duropathies encompass spinal dural tears and cerebrospinal fluid (CSF) leaks, often presenting with overlapping symptoms.
• Conditions include spontaneous intracranial hypotension (SIH), superficial siderosis (SS), spinal cord herniation, and arachnoid webs.

Purpose of the Study:

• To synthesize current literature on duropathies, focusing on clinical, neuroradiological, and pathophysiological aspects.
• To propose a unifying concept for duropathies to guide diagnosis and management.

Main Methods:

• Comprehensive literature review of conditions classified as duropathies.
• Analysis of diagnostic imaging techniques like MRI and CT myelography.

Main Results:

• SIH characterized by orthostatic headaches and neurological deficits; imaging shows specific spinal cord displacement patterns.
• Arachnoid webs frequently associated with syringomyelia.
• Persistent ventral spinal CSF leaks linked to SS and bibrachial amyotrophy.

Conclusions:

• Timely intervention for duropathies is crucial to prevent long-term neurological damage.
• Enhanced diagnostic strategies and a multidisciplinary approach are recommended for managing these complex disorders.
