[A case of mixed müllerian tumor, usefulness of 67Ga-citrate scintigraphy].

Mixed Müllerian Tumor (M.M.T.) is a rare malignant neoplasm usually arising from uterine body in postmenoposal woman, and imaging diagnosis for the tumor has not been established. A 45-year-old female with pathologically confirmed M.M.T. was evaluated by 67Ga-citrate scintigraphy and CT on the basis of imaging diagnosis. 67Ga-citrate scintigraphy detected correctly not only primary lesions but also metastatic and recurrent-foci. The findings of 67Ga-citrate scintigraphy were confirmed to be correspond to autopsy findings. Generally, detectability of 67Ga-citrate scintigraphy for genito-urinary tract neoplasm was not appreciated, but in our case 67Ga-citrate scintigraphy was useful for detection of the primary lesion, metastatic and recurrent foci. The cellular components and grade of cell-differentiation of this tumor seemed to be responsible for good detection of the tumor. Thus, 67Ga-citrate scintigraphy was considered to be useful diagnostic imaging modality of M.M.T.
