Expert second opinion for congenital brain and spine conditions
Radiology Prime provides independent specialist neuroradiology second opinions on brain and spinal MRI for congenital and developmental conditions — including Chiari malformations, tethered cord, spinal dysraphism, and cortical and cerebellar anomalies.
Reports are personally prepared within 24 hours by our Clinical Lead, a European-registered consultant neuroradiologist, flagging features worth raising with your neurologist or neurosurgeon.
Why these conditions benefit from sub-specialty review
Congenital and developmental conditions of the brain and spine are individually uncommon. Subtle measurements — how far the lower part of the cerebellum descends, the exact level where the spinal cord ends, the specific pattern of a brain’s cortical folds — can change the clinical picture meaningfully.
These conditions often need precise measurements and pattern recognition that sub-specialty neuroradiologists do routinely, but that aren’t part of every general radiologist’s regular practice.
When an independent review helps
Patients and families often seek a second opinion at specific moments — after a condition like Chiari malformation or tethered cord has been suggested on a scan done for another reason, when symptoms point toward a congenital cause but the original report was inconclusive, when a neurosurgical consultation is being planned and precise measurements matter for the discussion, or when weighing watch-and-wait monitoring against surgery. The report is written for direct use by the neurologist or neurosurgeon overseeing the case.
Sub-specialty expertise
Chiari malformations, tethered cord, spinal dysraphism, and cortical and cerebellar developmental differences are a core part of our Clinical Lead’s neuroradiology practice. Reports apply the standard classification systems used in neurosurgical and neurology practice — including Chiari grading, conus medullaris position measurement, and established frameworks for cortical malformations — alongside pattern-based discussion.
Independent perspective
These conditions are often first noticed on scans done for unrelated reasons — a headache workup that picks up low-lying cerebellar tonsils, a lumbar MRI for back pain that raises a question about where the spinal cord ends. An independent sub-specialty review gives you a second, focused read on whether the finding is clinically significant and what features are worth raising with the treating team.

Common challenges in congenital anomaly imaging
An independent review by our Clinical Lead provides precise measurements and structured pattern description for congenital findings, alongside a discussion of which features may be clinically significant. Each of the common interpretive challenges below is handled through that same structured approach.
When is Chiari malformation actually clinically significant?
The challenge: Chiari I malformation (where the lower part of the brain sits lower than usual, extending into the top of the spinal canal) is found on a significant proportion of MRIs done for unrelated reasons — headaches, dizziness, neck pain. Most cases don’t cause symptoms and don’t need treatment. The clinically important question is whether a given case is one of them.
The reality: The degree of tonsillar descent (measured in millimetres below a specific anatomical reference line), the shape of the descending tissue, whether the normal fluid spaces around the brainstem are preserved, and whether there is an associated syrinx (a fluid-filled cavity within the spinal cord) all contribute to whether a Chiari I finding is likely to be clinically significant. A syrinx in particular changes the clinical picture substantially and warrants prompt neurosurgical discussion.
What our review adds: Precise tonsillar descent measurement, structured assessment of the surrounding anatomy, and explicit syrinx screening, with a discussion of which features may be worth raising with the treating neurologist or neurosurgeon.
Is the spinal cord ending where it should?
The challenge: Tethered cord (a condition where the spinal cord is abnormally anchored within the spine, restricting its normal movement) is diagnosed partly on where the end of the spinal cord — the conus medullaris — sits on the scan, and partly on related features like the thickness of the filum terminale and the presence of associated findings.
The reality: In adults, the conus medullaris typically ends at the level of the L1–L2 intervertebral disc. A conus ending below this level on a lumbar MRI raises the possibility of tethered cord, particularly in a patient with symptoms that fit. But borderline positions are common, and the finding is meaningful only in clinical context.
What our review adds: Precise measurement of conus medullaris level against the vertebral anatomy, filum terminale thickness assessment, review for associated findings, and a structured discussion framed for the treating team.
Characterising spinal dysraphism and associated findings
The challenge: Spinal dysraphism (a group of developmental differences in how the spine and spinal cord formed) covers a wide range of conditions, from the severe and obvious to subtle closed forms that may be discovered incidentally in adulthood. Each subtype has different clinical implications.
The reality: The distinction between open forms (where the developmental difference involves the skin and is typically diagnosed at birth) and closed forms (where the skin is intact and the finding may be picked up much later on imaging) is fundamental. Within closed forms, specific entities — lipomyelomeningocele, diastematomyelia, dermal sinus tract, terminal syrinx — each have their own imaging pattern and their own clinical significance.
What our review adds: Structured characterisation of the specific entity, precise measurements of any associated findings, and a discussion of what the imaging features may be most consistent with — framed for neurosurgical review where relevant.
Recognising cortical and cerebellar developmental differences
The challenge: Developmental differences in how the brain’s outer layer (cortex) or the cerebellum formed are individually uncommon and have a wide range of presentations. They can be an important contributor to epilepsy, developmental issues, or neurological symptoms, but are often subtle on routine reporting.
The reality: Specific pattern recognition — the distribution and shape of the cortical folds, the presence of specific features like polymicrogyria or focal cortical dysplasia, the appearance of the cerebellar hemispheres and vermis — underpins both diagnosis and discussion of what may be clinically significant. Established classification frameworks exist for cortical malformations, and applying them gives a structured description rather than a general impression.
What our review adds: Pattern-based description using established classification frameworks, precise localisation of any findings, and a discussion of features worth raising with a neurologist — particularly where epilepsy or developmental symptoms are part of the picture.

Conditions reviewed by our Clinical Lead
Patients and families often seek a second opinion for these specific situations:
Chiari malformations and related conditions
Chiari I malformation: Precise tonsillar descent measurement, assessment of surrounding anatomy, and structured discussion of whether features are likely to be clinically significant.
Syringomyelia (syrinx): Dedicated assessment of fluid-filled cavities within the spinal cord — their location, dimensions, and any change over time if prior scans are available. Where a syrinx is identified, the report explicitly recommends prompt discussion with the treating neurologist or neurosurgeon.
Chiari II and related complex malformations: Review of the broader anatomy including associated brain and spine findings, where these have been identified.
Low-lying cerebellar tonsils picked up incidentally: Focused review of whether borderline findings on a scan done for another reason are likely to be clinically significant.
Tethered cord and spinal dysraphism
Tethered cord workup: Precise conus medullaris level measurement, filum terminale thickness assessment, and structured review of associated findings.
Closed spinal dysraphism picked up in adulthood: Characterisation of lipomyelomeningocele, diastematomyelia (split cord), dermal sinus tract, terminal syrinx, and related entities.
Post-operative tethered cord review: Assessment of imaging in patients who have had previous surgery and are being evaluated for possible re-tethering.

Frequently asked questions
A second opinion may provide a different view of your MRI or CT scan. Imaging studies are complex and can be interpreted in more than one way, especially when considered alongside your symptoms and medical history. In some cases, another review may point out subtle findings that are worth discussing further with your treating doctor before making decisions about treatment.
Yes — the report is intended to be shared with your neurologist. It is structured for peer-to-peer clinical use, with specific framework citations (McDonald, MAGNIMS) and cross-referenceable findings, alongside a plain-language summary for patients. The radiology report is personally signed by our Clinical Lead under her full name and credentials, as any hospital-generated radiology report would be. We encourage you to share it directly with your neurology team.
No. In most regions, patients may independently request a radiology second opinion.
Our service provides an independent subspecialty radiology review of your existing MRI or CT imaging. This evaluation is designed to support and not replace your treating physician’s clinical assessment.
We encourage discussing your second-opinion report with your doctor to determine the most appropriate next steps.
Second opinions are typically delivered within 24 hours, and many cases are completed sooner. Our radiology team prioritizes timely reviews to help you receive additional diagnostic insight as efficiently as possible.
The decision whether Chiari malformation needs surgery belongs with a neurosurgeon who knows your full clinical picture, not with a radiology report. What a second-opinion radiology report can do is give your neurosurgeon precise measurements and a structured description of the imaging features — tonsillar descent in millimetres, syrinx status, surrounding anatomy — that inform the discussion. Many Chiari I findings are incidental and not progressive; some are clinically significant and benefit from surgery. The imaging is an important input into that conversation but not the decision itself.
Incidental findings on lumbar MRIs done for back pain are a common reason for a second opinion. Our Clinical Lead reviews the scan specifically for developmental findings — conus medullaris level, filum terminale features, signs of dysraphism — and provides structured assessment framed for the neurology or neurosurgery consultation. Whether any finding is clinically significant is a judgement that belongs with the treating team, informed by your symptoms and examination.
Our technical support team can assist if you experience difficulty uploading your images. The website chat feature is available to help answer technical questions during the submission process.
