Participants eligible for inclusion in this study must meet all of the following criteria:
1. Lesion criteria applicable for therapeutic intervention
1. Safe accessibility of the lesion (within reach of aspiration needle; visible on ultrasound; transvaginal access; no interposition of bowel or blood vessels)
2. Lesion types included: cystic lesions (adnexal cysts), pelvic inclusion cysts (pseudocysts), pelvic abscesses
2. Indications
1. Pain relief in symptomatic cystic lesions with benign appearance.
2. Symptomatic treatment in probably malignant lesions (only in non-curative setting).

1. Patients \<18 years
2. Poor performance status contra-indicating the procedure
3. Vaginal stenosis (severe atrophy - virgo - vaginismus)
4. Purely solid lesions
5. Cystic lesions with a presumed malignant diagnosis and a risk of tumor dissemination in a curative setting
6. Physiological cysts in asymptomatic patients (in case of doubt the patient is reassessed after 3-6 months)
