- Abstract: Endosalpingiosis is a benign, non-neoplastic disease in which glandular tissue lined with ciliated tubal epithelium is ectopically present outside the fallopian tubes. Endosalpingiosis is rarely observed in the pelvic organs and its occurrence in the urinary bladder is particularly uncommon. Herein, we present a case of endosalpingiosis in the urinary bladder of a 62-year-old woman, which mimicked a bladder neoplasm, along with the corresponding magnetic resonance imaging (MRI) findings. The mass was a subepithelial lesion in the posterior portion of the urinary bladder dome. The lesion exhibited multiple cystic components with T2 high-intensity foci and mild heterogeneous enhancement on T1-weighted images. If there is a non-epithelial mass in the urinary bladder, especially on the posterior wall or dome, and the lesion exhibits MRI findings as described above, it is important to consider differential diagnoses, such as a non-neoplastic disease like endosalpingiosis.
