title: Sonographic and MRI findings in prepubertal adnexal hemorrhagic cyst with torsion.
abstract: Adnexal torsion is rare before menarche. We report the case of a 10-year-old girl with persistent left lower quadrant pain proven by surgery to be caused by adnexal torsion due to a hemorrhagic cyst. Sonography showed a well-defined, complex, predominantly solid mass with some sound through-transmission and a small amount of fluid. The left ovary could not be distinguished from the mass; the right ovary appeared normal. Doppler sonography demonstrated no blood flow within the mass. MRI revealed a circumferential region of high signal intensity in the periphery of the mass and multiple hyperintense foci in the left ovary.
