A well-defined round shaped unilocular cystic lesion is seen in the left adnexa measuring 40x40 mm. It shows fluid signal (hypointense on T1 and high signal on T2 weighted images), it has a thin wall with no evidence of fatty tissue, no internal septations or mural nodule could be seen and both ovaries are normal and separate from the cyst, the findings in favour of a paraovarian cyst.
