Summary

Skull-base metastases, common in breast and prostate cancer, often cause cranial nerve issues. Diagnosis relies on imaging like MRI, with treatment varying from radiotherapy to surgery, but prognosis remains poor.

Area of Science:

  • Oncology
  • Neurology
  • Radiology

Background:

  • Skull-base metastases are a significant complication, particularly in breast and prostate carcinoma.
  • Clinical presentation often involves progressive ipsilateral cranial nerve deficits.

Purpose of the Study:

  • To review the clinical features, diagnostic modalities, treatment options, and prognosis of skull-base metastases.

Main Methods:

  • Review of clinical syndromes associated with skull-base metastases.
  • Discussion of diagnostic imaging techniques including MRI, CT, and bone scans.
  • Overview of treatment strategies: radiotherapy, chemotherapy, hormonotherapy, surgery, and Gamma Knife radiosurgery.

Main Results:

  • Five distinct clinical syndromes are described based on metastatic site.

  • MRI is the primary diagnostic tool, though other imaging modalities are supplementary.
  • Treatment is multimodal and depends on the primary tumor's characteristics.
  • Gamma Knife radiosurgery offers an alternative for specific cases.

    • Conclusions:

    • Skull-base metastases are associated with a poor prognosis, with a median survival of approximately 2.5 years.
    • Late-stage presentation contributes to the overall poor outcome.
    • Multidisciplinary management is crucial for optimizing patient care.
