Summary
A rare case of pure struma ovarii is presented, highlighting imaging findings. Computed tomography (CT) and magnetic resonance (MR) revealed a complex ovarian mass with calcifications visible on CT.
Area of Science:
- Reproductive medicine
- Gynecologic pathology
- Diagnostic imaging
Background:
- Struma ovarii is a rare germ cell tumor of the ovary containing thyroid tissue.
- Pure struma ovarii, without other teratoma components, is exceptionally uncommon.
- Accurate preoperative diagnosis is crucial for appropriate management.
Observation:
- A case of pure struma ovarii is detailed.
- The patient presented with a complex ovarian mass.
- Both computed tomography (CT) and magnetic resonance (MR) imaging were utilized.
Findings:
- MR and CT imaging demonstrated a complex ovarian mass with both solid and cystic components.
- CT imaging identified calcifications within the mass.
- These calcifications were not apparent on MR imaging.
Implications:
- This case underscores the importance of multi-modal imaging in characterizing ovarian masses.
- CT's ability to detect calcifications can aid in differentiating struma ovarii from other ovarian neoplasms.
- Pathologic correlation remains essential for definitive diagnosis and treatment planning.
