Categorias num relance

Cat.	Significado	Conduta	Risco	Fonte
1	GI-RADS 1, definitively benign Definitively benign: normal ovaries identified with no adnexal mass/lesion.	—	Treated as the lowest-risk (essentially negligible malignancy) category.	okfonte PMC6215357 (Migda et al., J Ovarian Res 2018, GI-RADS + CA-125) Methods/Discussion (GI-RADS categories grouped 1-3 as low-risk, 4-5 as high-risk); cross-ref PMC6408110 (Tie et al., Medicine 2019) Introduction/Table 1
2	GI-RADS 2, very probably benign Most probably benign: an adnexal lesion with ultrasound features characteristic of a specific benign entity (for example a functional/follicular finding or a typical benign-appearing cyst).	—	Low-risk category (grouped with GI-RADS 1 and 3 as low risk in the cited studies).	okfonte PMC6215357 Methods/Discussion (categories 2-3 considered low-risk); PMC6408110 Table 1 (GI-RADS classifications) and Results
3	GI-RADS 3, probably benign Probably benign: an adnexal lesion thought benign but without clearly diagnostic features of a specific benign entity, and lacking findings suggestive of malignancy.	—	Low-risk category; in the cited cohort 2 of 120 GI-RADS 3 lesions proved malignant (~1.7%).	okfonte PMC6215357 Results ('2 cases of ovarian cancer classified in the low-risk category 3') and Discussion; PMC6408110 Results (GI-RADS 2-3 predominantly benign)
4	GI-RADS 4, probably malignant Probably malignant: an adnexal mass with one or more morphologic findings suspicious for malignancy - such as thick wall or thick septa, solid papillary projections, solid areas, central (intratumoral) blood flow on color Doppler, and/or ascites.	GI-RADS 4 (and 5) cases are recommended for referral to a gynecologic oncologist.	High-risk category; the cited source links the GI-RADS 4-5 referral recommendation to roughly a 20% risk of malignancy.	okfonte PMC6215357 Discussion ('GI-RADS 4 and 5 cases be referred to a gynecological oncologist due to the 20% risk of malignancy'); morphologic suspicious features listed in PMC6408110 Methods/Table 1
5	GI-RADS 5, very probably malignant Very probably malignant: an adnexal mass with two or more findings suggestive of malignancy among the suspicious features (thick wall/septa, solid papillary projections, solid areas, central blood flow, ascites).	Referral to a gynecologic oncologist recommended (high-risk group).	Highest-risk category; in the cited cohorts all GI-RADS 5 lesions were malignant (29/29 in one series; in another series no benign lesion was classified GI-RADS 5).	okfonte PMC6408110 Results ('All 29 adnexal masses classified as GI-RADS 5 were verified as malignant'); PMC6215357 Results (no benign GI-RADS 5)
