Pregnancy denial was observed in a patient after her second delivery. Contrary to the first pregnancy, she denied weight gain, body changes and baby movements. She reported using a contraceptive pill throughout the entire pregnancy. After a short home delivery without assistance, she was admitted to obstetrical department and referred for psychiatric evaluation. Mrs. T. accepted psychiatric follow-up appointments and was followed up for 6 months. She was initially assessed using the SCID II Interview, beck anxiety and depression interview, WHOQOL (WHO quality of life), and childhood trauma questionnaire. She denied pregnancy concealment and during the period of assessment and follow-up there was no evidence of intimate partner violence. Her female newborn was healthy without consequences of oestrogen/progesteron absorption (hypoplastic left heart syndrome, gastroschisis, hypospadias or congenital urinary trait anomalies) in one year follow up. The patient was discharged after 6 months of clinical outpatient follow-up. This case stresses and emphasizes the health and risk outcomes for both mother and child linked to an underestimated but serious phenomenon such as the denial of pregnancy.
