Use Cases

• Analyze the temporal association between cranial radiotherapy and secondary tumor development based on the 10-month latency period described.
• Study histopathological markers for differential diagnosis based on the reported SSTR2A, EMA, Ki-67, CD99, and FLI1 expression profiles.
• Review clinical presentation and imaging characteristics of olfactory groove meningiomas based on the detailed case description of symptoms and MRI/CT findings.

Strengths

• Includes specific clinical details such as patient age (38), radiotherapy dose (54 Gy in 27 fractions), and Ki-67 labeling index (2%–3%).
• Provides a complete clinical timeline from pre-radiotherapy imaging to one-year follow-up.
• Document is published under a permissive CC-BY-4.0 license for reuse.
