Summary
Ovarian dysgerminoma imaging on CT and MR shows characteristic fibrovascular septa. These findings correlate with pathology and aid in diagnosing this rare ovarian tumor.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Ovarian dysgerminoma is a rare germ cell tumor.
- Accurate imaging is crucial for diagnosis and management.
Observation:
- Retrospective review of CT and MR imaging in three patients with ovarian dysgerminoma.
- Correlation of imaging findings with histopathologic features.
Findings:
- Ovarian dysgerminomas exhibit lobulated masses divided by septa.
- These septa appear hypointense or isointense on T2-weighted MRI.
- Marked enhancement of septa is observed on contrast-enhanced CT and T1-weighted MRI.
- Histologic examination confirms these septa represent fibrovascular bundles.
Implications:
- Characteristic imaging findings of fibrovascular septa in solid ovarian masses suggest dysgerminoma.
- CT and MR imaging play a vital role in the preoperative diagnosis of ovarian dysgerminoma.
