title: I-123 uptake in nonfunctional struma ovarii.
abstract: A case of nonfunctional struma ovarii preoperatively diagnosed by scintigraphy of the pelvis using I-123 NaI is reported. US, CT, and MRI revealed a multilobulated mass composed of cystic and solid components. CT showed cystic components with slightly high density and MRI showed various signal intensities on T1- and T2-weighted images. I-123-scintigraphy of the pelvis showed uptake in the pelvic mass. Microscopic examination revealed the histologic appearance of thyroid tissue accompanied by follicular adenoma. I-123 scintigraphy of the pelvis was useful for reaching the correct preoperative diagnosis in this patient with nonfunctional struma ovarii.
