    Uterine adenomatoid tumors (ATs) are uncommon benign neoplasms arising from mesothelial tissue, often discovered incidentally during histopathological examination.

  • 2

    The study analyzed 16 surgically resected uterine ATs, revealing a median patient age of 51 years and coexistence with uterine fibroids in 8 cases.

  • 3

    MRI characteristics showed that ATs typically appear as solid masses with well-defined margins, lacking a discernible capsule, and may exhibit cystic degeneration.

  • 4

    On T1-weighted imaging, solid components of ATs are isointense, while T2-weighted imaging predominantly shows them as hypointense with possible 'target sign' features.

  • 5

    Histopathologically, uterine ATs consist of gland-like spaces among smooth muscle and fibrous tissue, correlating closely with their MRI findings.
