Background:
Placenta percreta is a rare obstetric condition associated with life-threatening hemorrhage. MR imaging has a role in prenatal diagnosis of these cases. However, its role in the postnatal diagnosis and in the follow up yet to be established.
Case:
A 33-year-old patient has adherent placenta following spontaneous delivery at 37 weeks gestation. MR imaging diagnosed placenta percreta. Intramuscular methotrexate treatment was initiated with follow up with serial beta-human chorionic gonadotrophin (beta-hCG). In spite of dropping of the level of beta-hCG, the trophoblastic tissue was still present 6 weeks postnatally where the patient complained of vaginal bleeding where she opted to abdominal hysterectomy.
Conclusion:
Patients who are suitable for non-surgical therapy, T2-weighted MR imaging may, in conjunction with serial beta-hCG assays, provide an alternative treatment modality for cases of placenta percreta.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
