Popis: 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.
Highlights • OMSTs are rare tumors with microcystic and solid regions with hyaline plaques. • OMSTs have peripheral solid soft tissue components with vascularity. • Solid components enhance on CT and MR, and have FDG avidity on PET imaging. • The clinical course of ovarian MST has a seemingly favorable outcome.
