Objective:

To explore the imaging characteristics of immature teratoma in the fetal oral cavity and improve diagnostic and differential diagnostic capabilities for this condition.

Key Findings:

• Imaging manifestations included a large solid-cystic mass in the fetal oropharynx, significant for differential diagnosis.
• CT revealed heterogeneous density with cystic appearance and punctate calcifications, a feature more commonly associated with immature teratomas.
• MRI showed irregular solid-cystic mass with specific signal characteristics correlating with histopathology, aiding in accurate diagnosis.

Interpretation:

Understanding the imaging features and associated intracranial abnormalities can significantly improve diagnostic proficiency for fetal oral cavity teratomas, impacting clinical decision-making.

Limitations:

• The rarity of the condition limits the number of available cases for comprehensive analysis, potentially affecting the generalizability of findings.
• Potential variability in imaging techniques and interpretations across different institutions may influence diagnostic outcomes.

Conclusion:

Multimodal imaging enhances prenatal diagnosis of immature teratomas, allowing differentiation from other oral masses and emphasizing the importance of evaluating concurrent intracranial abnormalities in clinical practice.
