Abstract

Sclerosing stromal tumors are rare benign ovarian neoplasms that are usually diagnosed in the second or third decade of life. Most patients with these tumors present with menstrual irregularities and pelvic pain. We present the magnetic resonance imaging (MRI) findings of a left ovarian sclerosing stromal tumor with torsion that was located in the right parauterine area, and discuss the differential diagnosis for this entity based on MRI findings. In this case, MRI demonstrated a well-defined, predominantly solid mass with a pseudolobular pattern, and showed a shift of the uterus to the left. The surgical and histopathologic aspects of the case are also described.
