The uterine appendages include the fallopian tubes and ovaries on both sides of the pelvis. When a uterine appendage mass is found, don’t be nervous, you need to combine medical history and physical examination to figure out the location and nature of the mass. The reasons for this are as follows: 1. Inflammatory masses, long-term pelvic inflammatory stimulation of the fallopian tubes or ovaries may lead to hydrosalpinx, tubal adhesions, ovarian inflammation, etc. Over time, inflammatory substances will wrap around to form a mass-like, can be timely anti-inflammatory treatment and then review. If the mass shrinks or even disappears, it means conservative treatment is effective. 2. physiological ovarian cysts, follicles are not discharged to form luteinized cysts, which will disappear on their own in 2-3 cycles and can be reviewed again. 3. fallopian tube tumors are relatively rare, while most adnexal tumors are ovarian, which have more tissue components, so they are more prone to tumors than fallopian tubes. The ovaries have more tissue components, so they are easier to develop tumors compared to the fallopian tubes. The cause of the tumor in the fallopian tube and ovary is not clear yet, so clinically it is recommended to check the tumor index first, and if it reaches 5cm or grows fast on review, surgery and pathological diagnosis is recommended.
