Leptomeningeal metastasis, a rare complication of breast cancer, can present as isolated nerve root pain. Early diagnosis using MRI and cerebrospinal fluid cytology is crucial for atypical symptoms in patients with a history of malignancy.

Area of Science:

  • Neurology
  • Oncology

Background:

  • Meningeal metastatic disease is typically a complication of brain tumors, rarely presenting in isolation with solid tumors.
  • The case involves a 74-year-old woman with a history of breast cancer presenting with refractory sciatica.

Observation:

  • The patient experienced severe sciatica, progressing to sphincter dysfunction and lower limb motor loss.
  • Initial diagnostic imaging (radiographs, CT, MRI) revealed spondylolisthesis, but cerebrospinal fluid (CSF) analysis was inconclusive.
  • A discrepancy between clinical presentation and initial imaging findings prompted further investigation.

Findings:

  • Repeated CSF analysis eventually revealed adenocarcinoma cells, and a subsequent MRI identified a mass in the dural sac.
  • The diagnosis was confirmed as leptomeningeal metastasis from breast cancer.

Implications:

  • This case highlights that leptomeningeal metastasis can manifest as isolated nerve root pain.
  • It underscores the diagnostic utility of MRI and CSF cytology in patients with unusual symptoms and a history of cancer.
  • Prompt and accurate diagnosis is vital for managing such rare oncological emergencies.
