Summary

Diagnosing pineal region tumors requires tissue confirmation. While open resection offers maximal tumor removal, stereotactic biopsy provides a less invasive option with high diagnostic accuracy for these intracranial lesions.

Area of Science:

  • Neurosurgery
  • Oncology
  • Pathology

Background:

  • Pineal region tumors constitute a small fraction (0.4%-1.0%) of all intracranial neoplasms.
  • Accurate tissue diagnosis is critical for effective management of pineal lesions.
  • Surgical intervention decisions balance diagnostic yield against invasiveness and risk.

Purpose of the Study:

  • To review the diagnostic accuracy and complication rates of stereotactic biopsy for pineal region lesions.
  • To compare stereotactic biopsy with open microsurgical resection for pineal tumors.

Main Methods:

  • Literature review of major series reporting stereotactic biopsy for pineal region lesions.
  • Analysis of diagnostic yield, morbidity, and mortality associated with stereotactic biopsy.

Published on: January 17, 2018

Main Results:

  • Stereotactic biopsy demonstrated a mean diagnostic yield of 94%.
  • The reported morbidity for stereotactic biopsy was 1.3%.
  • The mortality rate associated with stereotactic biopsy was 8.1%.

Conclusions:

  • Stereotactic biopsy is a valuable tool for diagnosing pineal region tumors, offering high diagnostic accuracy.
  • Open resection may be preferred for maximal tumor debulking and improved prognosis.
  • The choice between biopsy and resection depends on balancing diagnostic needs with procedural risks.
