[Diagnosis of pineal area tumors using computer tomography]

Area of Science:

• Neurology
• Radiology
• Oncology

Background:

• Germinomas in the pineal region are rare intracranial tumors.
• Accurate diagnosis and localization are crucial for effective treatment.

Purpose of the Study:

• To describe the utility of computer tomography (CT) in diagnosing pineal region germinomas.
• To highlight the role of CT in visualizing tumor characteristics and aiding surgical intervention.

Main Methods:

• Case series of three patients with pineal region germinoma.
• Diagnosis primarily based on computer tomography findings.
• Surgical verification of diagnosis.

Main Results:

• CT demonstrated three-dimensional, irregularly contoured structures in the posterior third ventricle.
• Contrast enhancement improved visualization of tumor boundaries.
• Central petrification was observed in all three cases.
• CT accurately localized the tumors, aiding surgical planning.

Conclusions:

• Computer tomography is a valuable diagnostic tool for pineal region germinomas.
• CT imaging provides crucial information regarding tumor size, shape, and calcification.
• The findings emphasize the importance of CT in the preoperative assessment and localization of these tumors.
