Summary

Magnetic resonance imaging (MRI) reveals key features of struma ovarii, a rare ovarian tumor. MRI findings include multilocular cystic masses with variable signal intensities, aiding in diagnosis.

Area of Science:

  • Radiology
  • Oncology
  • Pathology

Background:

  • Struma ovarii is a rare germ cell tumor of the ovary containing thyroid tissue.
  • Accurate preoperative diagnosis is crucial for appropriate management.
  • Magnetic resonance imaging (MRI) offers detailed anatomical and tissue characterization.

Observation:

  • This study details MRI findings in three confirmed cases of struma ovarii.
  • A multilocular cystic mass with heterogeneous signal intensity was consistently observed.
  • Specific signal characteristics on T1 and T2 weighted images correlated with pathological findings.

Findings:

  • Low signal intensity on T1 and very low signal intensity on T2 weighted images were noted in cystic loculi, indicative of gelatinous colloid.
  • Gd-DTPA enhanced T1 weighted imaging showed marked enhancement of thick septations and local wall thickening, corresponding to thyroidal tissue.
  • MRI effectively differentiates struma ovarii from other ovarian masses based on these characteristic features.

Implications:

  • MRI can accurately characterize struma ovarii, potentially improving preoperative diagnosis.
  • Understanding these MRI features can guide surgical planning and patient management.
  • Further research can refine MRI protocols for enhanced detection and characterization of ovarian neoplasms.
