Other Diagnostic Studies

Stereotactic biopsy

• A direct, visually guided biopsy of the pineal gland mass with open or neuroendoscopic surgery has been preferred due to concerns about injury to the deep cerebral veins.
• An open procedure also allows CSF to be obtained for
  • Tumor marker studies
  • Permits direct visualization of the third ventricle for staging purposes
  • Allows the third ventriculostomy to be performed for CSF diversion if needed.
• The diagnostic yield of stereotactic biopsy ranges from 94 to 100 percent.
• If the biopsy is nondiagnostic, equivocal, or suggests a benign tumor such as mature teratoma or meningioma, surgery is recommended to establish a definitive diagnosis or to identify focal areas of malignant disease
