In 2025, I was diagnosed with syringomyelia, a rare neurological condition characterized by the presence of a syrinx, a fluid-filled cyst within the spinal cord. My syrinx spans from C5 to C7, measuring 5mm at its largest point in C7, and has resulted in worsening neurological symptoms that fluctuate, significantly affecting my daily functioning. Like many others, I do not have Chiari I malformation or an obvious structural cause for this condition visible on standard MRI scans.

A noted neurosurgeon in Spain saw that I have a small posterior fossa and suggested that evaluating cerebrospinal fluid (CSF) flow dynamics through a cine MRI could provide vital insights into my condition. Despite this, my subsequent referrals were all denied, leaving my symptoms without explanation and hope of effective treatment. This unfortunate situation is commonplace because once a static MRI fails to reveal an obstruction or another obvious structural cause, the evaluation often concludes. This practice leaves many like me without a comprehensive diagnosis or treatment path.

Syringomyelia, when without Chiari I malformation or similar structural causes, should prompt further investigation into dynamic causes of obstruction or pressure differences. Abnormalities in CSF flow, for instance, should be exhaustively ruled out before classifying a syrinx as idiopathic or asymptomatic. Accurate diagnosis and understanding of the underlying causes can prevent progression of the condition and improve patient outcomes.

We call upon healthcare providers, policymakers, and medical boards to standardize the evaluation of syringomyelia for cases like mine. Clinicians should employ advanced imaging techniques, such as cine MRI, to assess CSF flow dynamics to ensure all potential causes are considered. Raising awareness and implementing these additional diagnostic steps will help countless individuals receive the comprehensive care they deserve.

Please join me in urging the medical community to adopt these thorough diagnostic protocols for syringomyelia cases. By signing this petition, we can advocate for improvements in patient care, enabling individuals with syringomyelia to understand their condition better and receive the treatment they need.

Proposal: Improving Diagnostic Evaluation Standards for Syringomyelia

Purpose

This proposal recommends updates to clinical evaluation practices before labeling syringomyelia as idiopathic or asymptomatic, in order to improve diagnostic accuracy and ensure appropriate access to care for patients experiencing neurological symptoms.

A syrinx forms as a result of disrupted cerebrospinal fluid (CSF) dynamics. However, current diagnostic practices frequently rely primarily on static MRI findings, which may fail to identify dynamic CSF flow abnormalities or subtle neurological dysfunction.

Before assigning an idiopathic or asymptomatic classification, additional evaluation steps should be considered when clinically indicated.

Barriers to Expanded Evaluation

Several barriers currently limit the use of additional diagnostic tools.

1. Limited Access to Specialized Imaging

Cine MRI and other advanced diagnostics are not available in many hospitals, particularly in rural or geographically isolated regions.

Proposed approach

Expand access through regional referral networks.

Allow telemedicine consultation with specialized neurosurgical centers.

Develop standardized referral pathways for complex syringomyelia cases.

2. Lack of Standardized Diagnostic Guidelines

There is currently no widely adopted diagnostic algorithm specifying which tests should be considered before labeling syringomyelia idiopathic or asymptomatic.

Proposed approach

Develop evidence-based diagnostic pathways through neurology and neurosurgery societies.

Encourage multidisciplinary input from neurology, neurosurgery, neuroradiology, and autonomic specialists.

Include guidance on when additional testing is appropriate.

3. Insurance and Coverage Limitations

Advanced diagnostic studies may be denied if clinicians believe a syrinx is incidental or asymptomatic.

Proposed approach

Establish diagnostic criteria that justify additional testing when neurological symptoms are present.

Encourage insurance coverage policies aligned with updated clinical guidelines.

4. Limited Awareness of Dynamic CSF Disorders

Dynamic CSF flow abnormalities may not be routinely considered when static MRI findings appear minimal.

Proposed approach

Increase education for clinicians on CSF dynamics and syringomyelia pathophysiology.

Support continuing medical education modules and clinical research initiatives.

Proposed Evaluation Framework

When a syrinx is identified and patients report neurological symptoms consistent with spinal cord dysfunction, clinicians should consider additional diagnostic evaluation before labeling the condition idiopathic or asymptomatic.

Potential diagnostic tools may include:

Cine MRI or phase-contrast MRI to evaluate CSF flow dynamics

Neurophysiological testing (e.g., somatosensory evoked potentials) when spinal cord conduction abnormalities are suspected

Additional neurological or autonomic testing when clinically indicated

These tools should be used judiciously and guided by clinical judgment, but their availability and consideration should be incorporated into diagnostic pathways.

Expected Benefits

Updating evaluation standards could:

Improve diagnostic accuracy

Reduce misclassification of symptomatic patients

Facilitate earlier identification of treatable causes

Improve access to appropriate care and research participation

Support better long-term outcomes for people living with syringomyelia.
