Surgical approaches to the pineal region

Area of Science:

• Neuro-oncology
• Surgical Pathology

Background:

• The pineal region hosts diverse histologic tumor subtypes.
• Optimal therapeutic strategies are tumor-type dependent.
• Accurate diagnosis is foundational for effective pineal tumor management.

Purpose of the Study:

• To highlight the importance of accurate diagnosis in pineal region tumors.
• To discuss the role of tissue sampling and emerging techniques in management.

Main Methods:

• Tissue acquisition through stereotactic biopsy or open surgery for pathologic examination.
• Review of emerging endoscopic techniques and stereotactic radiosurgery.

Main Results:

• Stereotactic biopsy is less invasive but carries higher sampling error risk than open surgery.
• Endoscopic techniques and stereotactic radiosurgery offer complementary management options.

Conclusions:

• Accurate histologic diagnosis is essential for guiding pineal tumor treatment.
• Surgical biopsy remains critical for diagnosis.
• Endoscopic approaches and radiosurgery represent advancements in neurosurgical armamentarium for pineal tumors.
