Ovarian microcystic stromal tumor (MST) is characterized by microcysts, solid cellular regions with lobulated growth, and collagenous or fibrous stroma forming hyaline plaques. While several reports have evaluated the unique pathologic and immunohistochemical profile of these tumors, there has been limited description of the radiologic findings of ovarian microcystic stromal tumor in the literature. We present a case of a 66 year old female who presented for evaluation of a new cystic pelvic mass found to have ovarian microcystic stromal tumor. To our knowledge, this is one of the first reports to evaluate the radiologic features associated with this tumor. An enhanced understanding of the correlation between imaging appearance and specific histopathologic findings may aid in the early recognition of this rare neoplasm.

Ovary microcystic stromal tumor (MCST) is an extremely rare subtype of sex cord-stromal neoplasm, and only 57 cases have been reported. We herein report a unique case of ovarian MCST with positive nestin expression in a 39-year-old Chinese woman. The tumor showed microcystic stromal histological structures and characteristically expressed the CD10, WT-1, and Ki67 proteins.
