Their exact nature is controversial. These SLMNs are classified as either benign or malignant. Benign mural nodules may appear sarcoma-like or have features of a leiomyoma. These benign nodules are associated with a favorable outcome and must be distinguished from anaplastic carcinoma and true sarcomatous nodules.

Acutely, a hemorrhagic ovarian cyst contains clotted blood, which at US manifests as intensely echogenic, avascular, homogeneous or heterogeneous nonshadowing material (Fig 6a).
