The purpose of this study is to discuss about the many different causes of myometrial hemorrhage, distinguishing benign from malignant causes based on MR imaging and about the ideal MR protocol to maximize bleeding detection.

1. Normal anatomy of the uterus, based on MR imaging and schematic drawings. 2. Myometrium variation according to hormonal status. 3. MR imaging protocol. How to maximize the detection of bleeding? 4. Causes of myometrial hemorrhage in the non-pregnant patient: - Non-tumoral: Adenomyoma, cystic adenomiosis, hematoma, unicornuate uterus with noncommunicating cavitary rudimentary horn. - Tumoral: Leiomyoma with red degeneration, leiomyosarcoma, myometrial invasion by endometrial cancer, Metastases.

Myometrial hemorrhage has a nonspecific clinical presentation, and may be found in benign and malignant diseases. MR imaging can properly assess myometrial anatomy and correctly diagnose the main causes of myometrial hemorrhage, allowing the radiologist to guide the correct treatment.
