What are the possible symptoms of Epstein-Barr virus-positive lymphadenitis in a severely immunocompromised 45-year-old male being evaluated for primary central nervous system lymphoma?

EBV+ Lymphadenitis Symptoms in Severely Immunocompromised Patient with Suspected Primary CNS Lymphoma

In a severely immunocompromised 45-year-old male with suspected primary CNS lymphoma, EBV+ lymphadenitis presents with persistent fever, lymphadenopathy, hepatosplenomegaly, and critically—neurological symptoms including cognitive dysfunction, memory deficits, headache, and visual changes that may herald CNS involvement.

Constitutional and Systemic Symptoms

The clinical presentation typically includes:

• Persistent or intermittent fever (prolonged, not self-limiting like typical infectious mononucleosis)
• Lymphadenopathy (cervical, axillary, mediastinal, hilar—may be tender or painless) 1
• Hepatosplenomegaly (splenomegaly is common) 1, 2
• Debilitating fatigue (recurrent or continuous, beyond typical tiredness)
• Sore throat and lymph node pain/tenderness
• Myalgia and arthralgia 1
• Significant weight loss 3
• Night sweats 3

Critical CNS-Specific Manifestations

Given the suspected primary CNS lymphoma context, neurological symptoms are particularly important:

• Cognitive dysfunction and memory loss (disorientation, poor memory) 4
• Headache 1
• Visual changes (blurry vision, vision loss—can be acute) 4
• Poor balance and coordination deficits 4
• Non-focal neurological symptoms initially, progressing to focal deficits 4

These neurological symptoms warrant immediate attention as they may indicate EBV-associated CNS lymphoproliferative disease or primary CNS lymphoma, which requires urgent intervention 5, 4.

Organ-Specific Complications

In severely immunocompromised patients, watch for multi-organ involvement 1:

Hematological

• Cytopenias
• Hemophagocytic lymphohistiocytosis (can develop during disease course) 1

Cardiovascular

• Coronary aneurysms (particularly concerning complication) 1
• Valvular disease 1

Dermatological

• Various cutaneous manifestations
• Hypersensitivity to mosquito bites (associated with T-cell lymphoproliferation) 1
• Hydroa vacciniforme-like eruptions 1

Other Systems

• Pulmonary complications
• Ocular manifestations (beyond visual field defects)
• Digestive tract disorders 1

Key Clinical Pitfalls

The most dangerous pitfall is misdiagnosing or delaying diagnosis of EBV-associated CNS lymphoma when periventricular lesions and neurological symptoms are present 4. In your patient:

1. Atypical presentations are common in immunocompromised hosts—symptoms may not follow the classic infectious mononucleosis pattern 4

2. Rapid progression can occur—neurological deficits may worsen quickly, requiring urgent tissue diagnosis 4

3. EBV-positive CSF with periventricular lesions on MRI strongly suggests EBV-associated CNS lymphoproliferative disease, even if initial biopsies are inconclusive 4

4. Clonal T-cell or NK-cell populations may develop—this represents progression from reactive lymphadenitis to lymphoma 1, 2

Diagnostic Urgency

In this severely immunocompromised patient with suspected primary CNS lymphoma, symptoms should prompt:

• Immediate brain MRI looking for unifocal or multifocal periventricular enhancing lesions 4
• CSF analysis with EBV PCR (quantitative viral load ≥10,000 IU/mL in whole blood supports diagnosis) 6
• Tissue diagnosis via biopsy if imaging shows concerning lesions, as EBV-PTLD can rapidly progress to high-grade lymphoma 5

The combination of systemic lymphadenopathy symptoms plus any neurological manifestations in this immunocompromised patient should trigger immediate evaluation for CNS involvement, as EBV-associated CNS lymphoproliferative disorders require urgent rituximab-based therapy or chemotherapy to prevent irreversible neurocognitive dysfunction 5.
