Orgasmic epilepsy can be an early sign of paraneoplastic limbic encephalitis, a rare autoimmune disorder linked to small cell lung cancer (SCLC). Prompt diagnosis and treatment of SCLC may improve outcomes for this neurological condition.

Area of Science:

  • Neurology
  • Oncology
  • Immunology

Background:

  • Paraneoplastic limbic encephalitis (PLE) is an autoimmune disorder often associated with occult malignancies.
  • Small cell lung cancer (SCLC) is a known cause of PLE, presenting with diverse neurological symptoms.

Observation:

  • A 57-year-old woman presented with orgasmic epilepsy, characterized by brief, pleasurable sensations.
  • She had a history of weight loss and heavy smoking, leading to the diagnosis of SCLC.

Findings:

  • Brain MRI revealed abnormalities in the left temporal lobe, and EEG showed focal sharp waves.
  • Serum anti-Hu antibodies confirmed PLE, and seizures resolved with carbamazepine.
  • Treatment of SCLC with chemotherapy and radiation led to complete remission.

Implications:

  • Orgasmic epilepsy can be a presenting symptom of PLE, aiding in the diagnosis of underlying SCLC.
  • Early detection and management of SCLC may positively impact the prognosis of PLE.
  • This case highlights the importance of considering paraneoplastic syndromes in patients with unexplained neurological symptoms.
