Rare Spine Tumor Case Dorsal Intraspinal B-Cell Non-Hodgkin Lymphoma in Two Patients

Introduction

Spinal cord compression is usually linked to common conditions such as herniated discs or degenerative spinal disease. However, rare malignancies can also present with similar symptoms, making diagnosis challenging. A recent case report highlights an unusual presentation of dorsal intraspinal B cell Non-Hodgkin lymphoma, demonstrating how this rare condition can mimic other neurological disorders and lead to serious complications if not detected early.

Understanding Non-Hodgkin Lymphoma and Spinal Involvement

Non-Hodgkin lymphoma (NHL) is a group of cancers that originate in the lymphatic system. Although it usually begins in lymph nodes, it can sometimes spread to other organs and tissues.

Key facts about spinal involvement in NHL include:

• NHL can arise from B-cells, T-cells, or natural killer cells.
• Spinal neurological complications occur in only about 0.6%–6.5% of patients.
• Tumor growth in the spinal canal may compress the spinal cord and cause neurological deficits.
• Early diagnosis is critical to prevent permanent damage.

Because symptoms such as back pain and limb weakness are common in many spinal disorders, identifying lymphoma-related compression can be difficult during early stages.

Case Study Overview Two Rare Patients

The study presents two elderly patients diagnosed with dorsal intraspinal Bcell Non-Hodgkin lymphoma. Read the full study at https://doi.org/10.29328/journal.aceo.1001015

Patient

A 77-year-old patient developed:

• Persistent cervical-dorsal pain
• Weakness in both arms
• Progressive neurological symptoms

MRI imaging revealed a lesion involving the C7–T2 vertebral region with spinal canal involvement. Additional scans showed pelvic lesions and retroperitoneal lymph node abnormalities.

Treatment involved:

• Decompressive laminectomy
• Tumor biopsy
• Chemotherapy using the R-CHOP regimen
• Radiotherapy

The patient showed significant tumor reduction following treatment.

Patient

A 78-year-old patient experienced:

• Gait instability
• Progressive leg weakness
• Numbness and sensory abnormalities
• Urinary retention

Spinal MRI identified an intramedullary lesion at the T4–T5 level, initially suspected to be ependymoma. Surgical partial excision and biopsy confirmed high-grade B-cell lymphoma. The patient received R-CHOP chemotherapy and responded favorably.

Why Early Detection Matters

Spinal cord compression caused by lymphoma is rare but potentially devastating. Common warning signs include:

• Persistent back or neck pain
• Limb weakness or numbness
• Radicular pain
• Difficulty walking
• Bladder dysfunction

Without prompt treatment, these symptoms may progress to paralysis or permanent neurological damage.

Role of MRI in Diagnosis

MRI is the most effective imaging method for identifying spinal cord lesions.

Key advantages of MRI include:

• High sensitivity for soft tissue tumors
• Ability to detect spinal cord compression
• Visualization of tumor extension into vertebrae or surrounding tissues

According to the World Health Organization, early cancer diagnosis significantly improves treatment outcomes and survival rates by enabling timely intervention and targeted therapy.

Treatment Approaches for Spinal Lymphoma

Management of spinal lymphoma typically involves a multidisciplinary approach.

Common treatments include:

• Surgical decompression to relieve spinal cord pressure
• Biopsy for definitive diagnosis
• Chemotherapy, often using the R-CHOP regimen
• Radiotherapy to reduce tumor mass
• Immunotherapy, such as rituximab

Clinical Implications for Orthopaedics and Neurosurgery

These cases highlight the importance of considering lymphoma in patients presenting with unexplained spinal cord compression.

Key clinical insights include:

• Rare tumors may mimic common spinal disorders.
• Early MRI screening is essential for neurological symptoms.
• Multidisciplinary treatment improves patient outcomes.
• Rapid progression of neurological deficits indicates urgent intervention.

Clinicians should remain vigilant when evaluating atypical spinal symptoms, particularly in elderly patients or those with a history of lymphoma.

Key Takeaways

• Dorsal intraspinal B-cell lymphoma is an extremely rare cause of spinal cord compression.
• Symptoms may resemble common spinal disorders, delaying diagnosis.
• MRI is the gold standard imaging technique for identifying spinal lesions.
• Early surgical and oncological treatment significantly improves prognosis.
