ICD-10: G83.81

Brown-Séquard syndrome (ICD-10 code G83.81) is a neurological condition resulting from hemisection of the spinal cord, leading to a characteristic pattern of motor and sensory deficits. The diagnosis of this syndrome involves a combination of clinical evaluation, patient history, and specific neurological examinations. Below are the key criteria and considerations used for diagnosing Brown-Séquard syndrome.

Clinical Presentation

1. Motor Deficits

Patients typically exhibit weakness or paralysis on one side of the body (ipsilateral side) due to damage to the corticospinal tract. This can manifest as:
- Hemiparesis: Partial weakness on the affected side.
- Hemiplegia: Complete paralysis on the affected side.

2. Sensory Deficits

Sensory loss is characterized by a dissociated pattern:
- Ipsilateral Loss: Loss of proprioception and vibratory sense on the same side as the injury due to damage to the dorsal columns.
- Contralateral Loss: Loss of pain and temperature sensation on the opposite side of the body due to damage to the spinothalamic tract.

3. Reflex Changes

Reflexes may be altered, with increased deep tendon reflexes on the ipsilateral side and possible changes in the contralateral side.

Diagnostic Criteria

1. Neurological Examination

A thorough neurological examination is essential to assess:
- Motor function: Strength testing to identify hemiparesis or hemiplegia.
- Sensory function: Testing for proprioception, vibration, and pain/temperature sensation.

2. Imaging Studies

• MRI or CT Scans: Imaging studies are crucial for visualizing the spinal cord and identifying any lesions, tumors, or trauma that may have caused the hemisection.

3. Patient History

• Trauma or Injury: A history of spinal cord injury, such as from a fall, gunshot wound, or other trauma, is often present.
• Onset of Symptoms: The timeline of symptom development can help differentiate Brown-Séquard syndrome from other neurological conditions.

4. Differential Diagnosis

It is important to rule out other conditions that may present similarly, such as:
- Multiple sclerosis
- Transverse myelitis
- Tumors affecting the spinal cord

Conclusion

The diagnosis of Brown-Séquard syndrome (ICD-10 code G83.81) relies on a combination of clinical findings, imaging studies, and patient history. The hallmark of this syndrome is the dissociated sensory and motor deficits resulting from hemisection of the spinal cord. Accurate diagnosis is crucial for effective management and rehabilitation of affected individuals. If you suspect Brown-Séquard syndrome, a prompt referral to a neurologist or specialist in spinal disorders is recommended for further evaluation and treatment planning.

Brown-Séquard syndrome, classified under ICD-10 code G83.81, is a neurological condition resulting from hemisection of the spinal cord. This syndrome is characterized by a unique pattern of motor and sensory deficits, which arise due to the disruption of specific neural pathways.

Clinical Description

Pathophysiology

Brown-Séquard syndrome typically occurs due to trauma, such as a spinal cord injury, tumors, or diseases that affect the spinal cord. The hemisection leads to a characteristic dissociation of sensory and motor functions. The injury affects the lateral and anterior columns of the spinal cord, resulting in the following clinical features:

• Ipsilateral Motor Loss: Patients experience weakness or paralysis on the same side as the injury (ipsilateral side). This occurs because the corticospinal tract, which carries motor signals from the brain to the body, decussates (crosses over) at the level of the medulla, meaning that damage to one side of the spinal cord affects motor function on the same side.

• Contralateral Sensory Loss: Sensory loss, particularly pain and temperature sensation, occurs on the opposite side (contralateral side) of the body. This is due to the crossing of the spinothalamic tract fibers, which carry pain and temperature sensations, at the level of the spinal cord.

Symptoms

The symptoms of Brown-Séquard syndrome can vary based on the level of the spinal cord affected but generally include:

• Motor Symptoms: Weakness or paralysis of the limbs on the same side as the injury.
• Sensory Symptoms: Loss of pain and temperature sensation on the opposite side, while proprioception and vibratory sense may remain intact on the same side as the injury.
• Autonomic Dysfunction: In some cases, patients may experience bladder and bowel dysfunction, sexual dysfunction, and other autonomic symptoms.

Diagnosis

Diagnosis of Brown-Séquard syndrome typically involves a thorough clinical examination, patient history, and imaging studies such as MRI or CT scans to visualize the spinal cord and identify the extent of the injury. Electromyography (EMG) and nerve conduction studies may also be utilized to assess the function of the nerves and muscles.

Treatment

Management of Brown-Séquard syndrome focuses on rehabilitation and supportive care. Treatment options may include:

• Physical Therapy: To improve strength, mobility, and function.
• Occupational Therapy: To assist with daily living activities and adaptations.
• Medications: To manage pain, spasticity, and other symptoms.
• Surgery: In cases where there is a compressive lesion or significant structural damage, surgical intervention may be necessary.

Prognosis

The prognosis for individuals with Brown-Séquard syndrome varies widely depending on the cause and extent of the spinal cord injury. Some patients may experience significant recovery, while others may have lasting deficits. Early intervention and rehabilitation are crucial for optimizing outcomes.

In summary, Brown-Séquard syndrome (ICD-10 code G83.81) is a complex condition resulting from spinal cord hemisection, leading to a distinctive pattern of motor and sensory deficits. Understanding its clinical features, diagnosis, and treatment options is essential for effective management and rehabilitation of affected individuals[2][10][12].

This syndrome is characterized by a distinct clinical presentation, including a combination of motor and sensory deficits that vary depending on the level and extent of the spinal cord injury.

Clinical Presentation

Signs and Symptoms

1. Motor Deficits:
   - Patients typically exhibit weakness or paralysis on the side of the body that is opposite to the injury (contralateral side). This is due to the disruption of the corticospinal tract, which carries motor signals from the brain to the body.
   - The affected side may show signs of spasticity or increased muscle tone, while the contralateral side may present with flaccid paralysis.

2. Sensory Deficits:
   - Contralateral Loss of Pain and Temperature Sensation: The loss of these sensations occurs due to damage to the spinothalamic tract, which transmits pain and temperature sensations from the body to the brain.
   - Ipsilateral Loss of Proprioception and Vibration Sense: The patient may experience loss of proprioception and vibration sense on the same side as the injury, attributed to damage to the dorsal columns of the spinal cord.

3. Autonomic Dysfunction:
   - Some patients may experience autonomic dysregulation, which can manifest as changes in blood pressure, heart rate, and bladder control.

Patient Characteristics

• Demographics: Brown-Séquard syndrome can affect individuals of any age, but it is more commonly seen in young adults due to trauma-related injuries, such as those from motor vehicle accidents or sports injuries.
• Underlying Conditions: In some cases, the syndrome may arise from non-traumatic causes, such as tumors, infections, or vascular issues affecting the spinal cord.
• Severity of Injury: The extent of the neurological deficits can vary significantly based on the severity and location of the spinal cord injury. Complete hemisection may lead to more pronounced symptoms compared to partial injuries.

Diagnosis and Evaluation

Diagnosis of Brown-Séquard syndrome typically involves a thorough clinical evaluation, including a detailed neurological examination to assess motor and sensory function. Imaging studies, such as MRI or CT scans, are often employed to visualize the spinal cord and identify the underlying cause of the hemisection.
