Summary
Epilepsia partialis continua, a rare neurological disorder, can be an early sign of small cell lung cancer. This case highlights the importance of considering paraneoplastic syndromes in neurological presentations.
Area of Science:
- Neurology
- Oncology
Background:
- Paraneoplastic syndromes can present with diverse neurological symptoms.
- Small cell lung cancer (SCLC) is known to be associated with paraneoplastic neurological disorders.
Observation:
- A 46-year-old female presented with epilepsia partialis continua, initially misdiagnosed as brain metastases from SCLC.
- Neurological symptoms and intracranial lesions resolved with standard cancer treatment and corticosteroids.
- Symptoms recurred 18 months later, affecting different CNS areas without tumor recurrence, but responded to immunosuppressive therapy.
Findings:
- The patient's initial presentation mimicked brain metastases but responded to cancer therapy.
- Recurrent neurological symptoms, despite no tumor recurrence, suggested an autoimmune or paraneoplastic process.
- Distinctive response to immunosuppressive therapy indicated an inflammatory or immune-mediated etiology.
Implications:
- This case underscores the diagnostic challenges of paraneoplastic multifocal encephalitis.
- Early recognition and appropriate immunosuppressive therapy are crucial for managing paraneoplastic neurological disorders.
- Highlights the need for a broad differential diagnosis in patients with neurological symptoms and underlying malignancy.
