A 35-year-old G4P3 with previous two cesarean sections presents at 28 weeks with anterior placenta previa. MRI shows dark intraplacental T2 bands, heterogeneous placental signal, and bulging of the placenta into the bladder. These findings are most suggestive of:
- A Placenta accreta
- B Placenta increta
- C Placenta percreta ✓
- D Placenta previa without invasion
Correct answer: C. Placenta percreta
Explanation
MRI findings of dark T2 bands, heterogeneous signal, and bulging into adjacent organs (bladder) are characteristic of placenta percreta, where villi penetrate through the myometrium to the serosa or beyond. Accreta shows adherence without invasion. Increta invades into myometrium but not through it. These MRI features are part of the grading system for PAS severity.
