Balo Concentric Sclerosis: Symptoms, Diagnosis, Treatment

PhilArticles, Blog

Balo concentric sclerosis is a rare and aggressive form of the demyelinating disease multiple sclerosis with typical MS lesions. Discovered by József Balo in 1928, this disease features unique, concentric rings of demyelination in the brain, like lesions seen in typical MS lesions and demyelinating lesions in the spinal cord. These patterns, like lesions, make it distinct from other types of MS. It’s crucial to understand its characteristics, symptoms, and treatment options for better management of the disease onset.

People often confuse it with more common neurological disorders like lesions and demyelinating disease due to overlapping symptoms. However, the hallmark ring-like lesions set it apart. Advances in MRI technology have made diagnosing this condition easier, offering hope for early intervention in patients with disorders at disease onset.

Unveiling Baló Concentric Sclerosis


Baló concentric sclerosis is a rare, severe monophasic demyelinating disease with onset treated by rituximab medicine. It is considered a subtype of multiple sclerosis (MS). This condition leads to the loss of myelin in the brain, as seen on MR imaging.

Unique MRI Appearance

MRI scans show a unique ‘bullseye’ or ‘onion bulb’ appearance with a concentric pattern in the center on T2 medicine. This is due to alternating layers of high and low signal intensity in a concentric pattern on T2 MR imaging in patients. These patterns are called concentric layers.

Demographic Pattern

Baló concentric sclerosis predominantly affects balo patients of Han Chinese and Filipino descent. The disease is very rare. Its occurrence in these specific demographics highlights its distinct pattern in patients, as noted in the article on the case onset.


Patients may experience various symptoms:

  • Left hemiparesis
  • Cognitive impairment
  • Visual disturbances

These symptoms often mimic those seen in typical MS lesions on MR imaging in patients with T2 medicine.


The hallmark of Baló concentric sclerosis in patients is the presence of alternating bands of preserved myelin and demyelinated areas as seen on MR imaging. This results in concentric rings visible on imaging studies.


Diagnosis involves MRI scans that reveal the characteristic concentric pattern in patients with T2 medicine. Other tests may include cerebrospinal fluid analysis, MR imaging, and blood tests to rule out other conditions, such as systemic lupus erythematosus.


Treatment options are limited but may include:

  • High-dose corticosteroids
  • Plasma exchange
  • Immunosuppressive therapy

These treatments aim to reduce inflammation in patients and slow disease progression.

Historical Insights and Etymology

József Baló’s Contribution

József Baló first identified the disease in 1928. He proposed the term “Leuko-encephalitis periaxialis concentrica” in his article. This name reflects the unique pattern of damage seen in the brain of patients in medicine school.

Baló described concentric layers of damaged and preserved myelin. These layers look like onion bulbs when examined under a microscope in the school medicine department article. His work laid the foundation for understanding this rare disease in patients, as detailed in his article.

Naming Reflects Pathology

The name Baló concentric sclerosis highlights its pathological characteristics. The term ‘concentric’ refers to the ring-like patterns of lesions in patients as described in the article on gd. These rings alternate between damaged and intact myelin.

This pattern is distinct from other demyelinating diseases. It helps doctors identify Baló concentric sclerosis more easily. The characteristic appearance is crucial for diagnosis.

Evolution of Understanding

Our understanding of Baló concentric sclerosis has evolved since its discovery, with insights from patients and recent articles. Initially, it was considered a variant of multiple sclerosis (MS) in patients. Over time, researchers found differences that set it apart.

In 1966, Adams et al. published an article detailing these differences in patients with GD. They noted that gd onset often occurs in younger patients compared to typical MS cases. The progression can be rapid and severe.

Recent studies have used advanced imaging techniques to study the disease further in patients with gd. MRI scans reveal more about the lesion patterns and their development over time in patients. This has improved diagnostic accuracy.

Key Historical Milestones

Several key milestones mark the history of Baló concentric sclerosis patients.

  1. In 1928, József Baló identified and named the disease.
  2. In 1966, Adams et al.’s study highlighted important distinctions from MS patients.
  3. Advances in MRI technology have refined our understanding of patients in recent years.

These milestones show how knowledge has grown over decades. Each step has brought us closer to effective treatments and better patient outcomes for patients.

Key Clinical and Radiologic Features

Clinical Presentation

Patients with Baló concentric sclerosis often present with rapid progression of symptoms. These symptoms may include weakness, vision problems, and coordination issues in patients. They can be similar to those seen in other forms of multiple sclerosis (MS) patients. However, the speed at which these symptoms develop is typically faster in patients with Baló concentric sclerosis.

Neurologic examination frequently reveals significant deficits. These deficits may affect patients’ motor skills, sensory perception, and cognitive functions. Symptom onset is usually acute or subacute.

Imaging Findings

MRI imaging is crucial for diagnosing Baló concentric sclerosis. One of the hallmark features in patients is the presence of concentric rings or stripes of alternating signal intensity. These rings are visible on T2-weighted MRI scans of patients.

On T1-weighted MRI without contrast, these lesions in patients appear as irregular areas of iso and low signal intensity. When gadolinium contrast is used (T1 C+), patients often show prominent enhancement of the lesions. This enhancement helps differentiate Baló from other types of MS lesions in patients.

Comparison with Typical MS Lesions

Typical MS lesions do not usually exhibit the concentric ring pattern seen in Baló concentric sclerosis patients. In standard MS, patients’ brain lesions are more uniform and lack the alternating signal intensities on MRI scans.

Baló’s tumefactive lesions in patients can also be larger than those found in typical MS cases. The lesion size in patients can sometimes mimic brain tumors, making accurate diagnosis essential.

Diagnostic Criteria

Diagnosis involves both clinical and radiologic criteria. Clinicians consider rapid symptom progression and specific neurologic findings in patients during neurologic examination. Radiologists look for characteristic imaging findings in patients, such as concentric rings or stripes on MRI.

Case reports have documented these features extensively. Each case report adds to the understanding of this rare disease in patients.

Case Reports

Several case reports highlight unique aspects of Baló concentric sclerosis in patients. For instance, one case report described a young adult patient with sudden onset of severe neurological deficits. MR imaging revealed classic concentric ring patterns in patients that led to a definitive diagnosis.

These reports emphasize the importance of recognizing distinct imaging characteristics in patients early on.

Deep Dive into Pathology

Alternating Bands

Baló concentric sclerosis features alternating bands of demyelinated and myelinated white matter in patients. This pattern creates a unique imaging appearance. Demyelination means the loss of the protective covering around nerve fibers, called myelin, in patients. Myelin helps in fast signal transmission in the brain.

The alternating bands are visible on MRI scans. These bands look like rings or layers. The demyelinated areas in patients appear dark, while the myelinated ones look bright. This distinct pattern sets Baló concentric sclerosis apart from other diseases in patients.

Concentric Layers

The concentric layers of demyelination and preserved myelin are crucial for understanding this disease in patients. These layers show how the disease progresses over time. Demyelination occurs in waves in patients, leading to these ring-like structures.

Pathologists study brain tissue samples to observe these layers. A biopsy can reveal these patterns under a microscope. The concentric layers help doctors understand the extent of damage in patients and predict disease progression.

Microscopic Differentiation

At a microscopic level, Baló concentric sclerosis differs from other demyelinating diseases in patients. Diseases like multiple sclerosis (MS) also involve demyelination in patients but lack the concentric layering seen in Baló’s disease.

In MS, lesions are more scattered and irregular. In contrast, Baló’s lesions form organized rings. This difference is significant for diagnosis.

Biopsy evidence plays a key role here. Tissue samples show clear boundaries between demyelinated and myelinated regions in patients with Baló’s disease. This clarity aids patients in differential diagnosis, distinguishing it from similar disorders.

Disease Mechanism

Understanding the pathology behind these features sheds light on the disease mechanism in patients. The alternating bands suggest a cyclical process of damage and repair.

Cells involved in immune response attack myelin repeatedly. Each attack wave creates a new ring of demyelination. Between attacks, some healing occurs, preserving certain myelin areas.

This cyclical nature might explain why symptoms vary over time in patients. Patients may experience periods of worsening followed by partial recovery.

Clinical Course

The clinical course of Baló concentric sclerosis in patients can be severe due to rapid progression of lesions. Early detection is vital to managing symptoms effectively.

Doctors rely on MRI scans to monitor lesion development in patients over time. Regular imaging helps track changes in lesion size and number in patients.

Treatment focuses on slowing down the immune attacks causing demyelination in patients. Medicines like corticosteroids can reduce inflammation during acute phases.

Overview of Treatment Strategies

Initial Treatment

Corticosteroids are commonly used in managing acute flares of Baló concentric sclerosis in patients. These drugs help reduce inflammation. They can also lessen the severity of symptoms. The typical dosage is high, often administered intravenously.

However, corticosteroids come with limitations. Long-term use can lead to side effects like weakened bones and increased infection risk in patients. Some patients may not respond well to these drugs.

Disease Control

Due to its rarity, there are no specific treatments for Baló concentric sclerosis patients. Doctors often borrow strategies from multiple sclerosis (MS) management. MS treatments aim to control disease progression and manage patients’ symptoms.

Cyclophosphamide is sometimes used in severe cases. This drug suppresses the immune system in patients, which might help in reducing inflammation and damage.

Experimental Treatments

Researchers continue to explore new treatments for patients with Baló concentric sclerosis. Ongoing studies focus on understanding the unique challenges of this disease for patients.

One area of research involves humoral responses. Scientists are examining how antibodies in patients contribute to the disease’s progression. They hope that targeting these responses could offer new treatment options for patients.

Another promising area is imaging techniques. Advanced images like T1-weighted MRI scans help doctors see changes in brain tissues of patients more clearly. These images can show areas of peripheral enhancement in patients, indicating active disease sites.

Funding and Research Support

Funding remains a significant hurdle for Baló concentric sclerosis research. Because it is rare, attracting investments can be challenging. However, some groups are dedicated to raising awareness and funds for this cause.

Prognosis Insights

Rapid progression

Baló concentric sclerosis often shows rapid progression. However, it is not always fatal. The prognosis can vary widely among individuals. Some patients may experience severe symptoms quickly, while others have a more prolonged course.

Early detection plays a crucial role in managing the disease. MRI imaging helps identify the characteristic concentric rings and signal intensity changes. This aids in diagnosing the condition early.

Factors influencing prognosis

Several factors influence the prognosis of Baló concentric sclerosis. One key factor is the effectiveness of treatment during acute phases. Treatments like steroids and immunosuppressive therapies can reduce inflammation and slow disease progression.

Another important factor is ongoing monitoring. Regular check-ups help track disease activity and adjust treatments as needed.

Supportive care also improves outcomes. Physical therapy, occupational therapy, and cognitive rehabilitation help manage symptoms and maintain quality of life.

Clinical relapse

Clinical relapses are common in Baló concentric sclerosis. Patients often experience periods of worsening symptoms followed by partial recovery. These relapses can lead to further neurological damage if not managed promptly.

Effective treatment during relapses is essential. Medications like rituximab have shown promise in reducing relapse frequency and severity.

Cognitive impairment

Cognitive impairment is another concern for patients with Baló concentric sclerosis. Memory loss, difficulty concentrating, and other cognitive issues can significantly impact daily life.

Early intervention with cognitive therapies can help mitigate these effects. Support from family and healthcare providers is also crucial in managing these challenges.

Imaging findings

Imaging findings play a vital role in understanding Baló concentric sclerosis. MRI scans reveal distinctive patterns that aid diagnosis and monitor disease progression.

The inversion time on MRI helps differentiate Baló lesions from other types of brain lesions. Changes in signal intensity provide insights into disease activity and response to treatment.
