Computed Tomography in the Evaluation of Carcinoma of the Ovary

Abstract

Over a 26 month period, 34 patients with histologically proven ovarian malignancy were studied by computed tomography (CT). In nine patients, CT was obtained for evaluation of a pelvic or abdominal mass. Computed tomography was diagnostic of ovarian malignancy in seven and indeterminate regarding the origin of the tumor in two patients. Ten patients were evaluated by CT in order to rule out recurrent ovarian neoplasm. Disease free intervals prior to CT ranged from 6 to 36 months with an average of 18 months. In eight surgically proven cases, CT was true positive for recurrent tumor in six patients, true negative in one, and false positive in one. In 20 patients, serial CT examinations were valuable in the objective assessment of measurable tumor response following chemotherapy and radiation therapy. A major limitation of CT was its inability to detect peritoneal and liver surface implants smaller than 2 cm in size.
