Placenta accreta spectrum (PAS) represents a complex obstetric condition characterised by the abnormal invasion of anchoring villi and trophoblast into the myometrium. This case report explores two instances where the diagnosis of PAS was overlooked during antenatal care leading to significant complications during conservative management. Both patients presented with heavy menstrual bleeding and raised beta human chorionic gonadotrophin (β-hCG), mimicking gestational trophoblastic disease. The report delves into the clinical presentations, diagnostic challenges, and outcomes of two cases, shedding light on the importance of effective communication and follow-up in the management of PAS.
