Abstract:
The magnetic resonance (MR) appearances of three cases of atypical polypoid adenomyoma are reported. The signal intensity of the tumor was similar to that of adenomyosis on T2-weighted MR Imaging (MRI). On contrast-enhanced study, irregular enhancement was seen in hyperintense areas on T2-weighted images. Atypical polypoid adenomyoma can be characterized as a hypointense polypoid mass with hyperintense foci on T2-weighted MR images, resembling the appearance of adenomyosis.
Insights
Magnetic resonance imaging (MRI) reveals atypical polypoid adenomyoma often mimics adenomyosis on T2-weighted scans. This rare tumor presents as a hypointense mass with hyperintense foci, showing irregular enhancement after contrast administration.
Area of Science:
- Medical Imaging
- Radiology
- Gynecologic Pathology
Background:
- Atypical polypoid adenomyoma is a rare uterine tumor.
- Distinguishing it from other uterine pathologies can be challenging.
- Magnetic resonance imaging (MRI) is a key diagnostic tool.
