Fig. 1B. 57-year-old woman with recurrent ovarian cancer. Position
emission tomography scan shows intense uptake in mediastinum (arrow)
in addition to those in pelvic region (arrowheads). H and B identify
physiologic uptakes in heart and bladder, respectively.

Fig. 1C. 57-year-old woman with recurrent ovarian cancer. Thoracic CT
scan reveals lymphadenopathy (arrow), suggesting metastases to
mediastinal lymph nodes. Chemotherapy was performed before surgery, and size
of enlarged nodes was reduced on follow-up CT scan (not shown), suggesting
malignant involvement.

Fig. 2. 47-year-old woman with recurrent ovarian cancer. Conventional
modalities, including CT and sonography, in follow-up period revealed no
definite findings of metastasis or recurrence, but coronal (left) and
sagittal (right) 18F-fluorodeoxyglucose position emission
tomography scans show focal intense uptake adjacent to liver
(arrows). Peritoneal dissemination was confirmed at surgery.
