Summary
Limbic encephalitis, a rare paraneoplastic syndrome, can present initially with seizures. Early diagnosis of underlying small cell lung cancer, even without anti-Hu antibodies, is crucial for treatment and improved outcomes.
Area of Science:
- Neurology
- Oncology
- Medical Imaging
Background:
- Limbic encephalitis is an uncommon manifestation of paraneoplastic syndromes.
- Seizures are a recognized symptom of limbic encephalitis.
Observation:
- A 69-year-old woman presented with nonconvulsive status epilepticus and neuropsychiatric symptoms.
- Imaging revealed mediastinal lymphadenopathy and lung nodules, leading to a small cell lung carcinoma diagnosis.
- Cerebrospinal fluid was normal, but EEG and MRI indicated temporo-limbic dysfunction.
Findings:
- Anti-Hu antibodies were negative, challenging typical paraneoplastic limbic encephalitis associations.
- Symptoms improved with chemotherapy and radiotherapy for small cell lung cancer.
- Follow-up MRI showed no intracranial metastasis.
Implications:
- Status epilepticus can be an early indicator of limbic encephalitis.
- The absence of anti-Hu antibodies does not exclude small cell lung cancer in limbic encephalitis cases.
- Prompt diagnosis and treatment of the primary lung cancer are vital for patient prognosis.
