Summary
This study details a rare case of sequential anti-Ma2 encephalitis and herpes simplex encephalitis in a 67-year-old man. Prompt treatment led to significant recovery, challenging initial prognoses.
Area of Science:
- Neurology
- Immunology
- Oncology
Background:
- Paraneoplastic encephalitis (PNE) and herpes simplex encephalitis (HSE) are distinct neurological conditions.
- Anti-Ma2-associated PNE is a rare autoimmune disorder often linked to cancer.
- HSE is a viral infection of the brain.
Observation:
- A 67-year-old male presented with sequential anti-Ma2-associated PNE and contralateral HSE.
- Brain biopsy showed significant T cell, B cell, and plasma cell infiltration.
- T cells expressed cytotoxic markers TIA-1 and granzyme-B.
Findings:
- Despite a grave prognosis, the patient showed dramatic improvement after PNE treatment.
- Treatment involved corticosteroids and resection of an associated lung cancer.
- The patient experienced 21 months of significant recovery.
Implications:
- This case highlights the potential for significant recovery in complex encephalitis cases.
- It underscores the importance of multimodal treatment strategies.
- Further research into T cell-mediated mechanisms in PNE and HSE is warranted.

01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:15Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
