Radiology of suprasellar ectopic pinealoma

Area of Science:

• Neuro-oncology
• Pediatric Radiology
• Neurosurgery

Background:

• Suprasellar ectopic pinealomas are rare tumors.
• Review of 23 reported and 3 new cases.
• Focus on radiographic and clinical presentation.

Observation:

• Suprasellar calcification is exceptionally rare.
• Sella turcica enlargement observed in 20-30% of cases.
• No elevation of the anterior cerebral artery noted.

Findings:

• Pneumography may reveal anterior third ventricle filling defects.
• Isotope uptake in the suprasellar region observed in one new case.
• Differential diagnosis and clinical data discussed.

Implications:

• Aids in the diagnosis of rare suprasellar tumors.
• Highlights key radiographic indicators for clinicians.
• Contributes to understanding the spectrum of pinealoma presentations.
