Summary

Magnetic resonance (MR) imaging effectively depicts adenoma malignum, a rare cervical cancer. This rare uterine cervical adenocarcinoma presents as a multicystic mass with solid components, best visualized with contrast-enhanced MR imaging.

Area of Science:

  • Gynecologic Oncology
  • Radiology
  • Pathology

Background:

  • Adenoma malignum is a rare, aggressive variant of uterine cervical adenocarcinoma.
  • Accurate diagnosis is crucial for effective management and improved patient outcomes.

Purpose of the Study:

  • To evaluate the clinical, pathologic, and magnetic resonance (MR) imaging findings of adenoma malignum.
  • To correlate MR imaging features with histopathologic findings.

Main Methods:

  • Retrospective review of medical records for 7 patients diagnosed with adenoma malignum.
  • Evaluation of unenhanced T1- and T2-weighted and gadolinium-enhanced T1-weighted MR images.
  • Correlation of imaging findings with gross and microscopic pathologic features.

Main Results:

  • Cervical enlargement was observed in 5 of 7 patients.
  • Adenoma malignum appeared as multiple cystic lesions in the deep cervical stroma, hyperintense on T2-weighted images.
  • Gadolinium-enhanced T1-weighted MR imaging best delineated the multicystic and solid components of the tumor.

Conclusions:

  • MR imaging is valuable for depicting adenoma malignum as a multicystic mass with solid portions.
  • Gadolinium enhancement aids in identifying the solid components of adenoma malignum.
  • MR imaging findings correlate with pathologic features of this rare cervical adenocarcinoma.
