CT features of serous surface papillary carcinoma of the ovary.
OBJECTIVE
The purpose of this study was to determine the CT appearance of serous surface papillary carcinoma of the ovary.


METHODS
CT scans of 17 patients with histologically proven serous surface papillary carcinoma of the ovary were retrospectively reviewed. We evaluated the ovary size, omental or mesenteric involvement (none, mild, or severe), ascites (none, small, moderate, or large), and peritoneal thickening (none, smooth, or nodular). We also noted the presence of a cul-de-sac mass, lymphadenopathy, and calcification within the peritoneal mass. The preoperative serum level of cancer antigen (CA)-125 was assessed in all patients.


RESULTS
The diameter of ovaries was 3 cm or smaller in 14 patients (82%). All patients had omental or mesenteric involvement by the tumor (mild, n = 2; severe, n = 15) and ascites (small, n = 1; moderate, n = 3; large, n = 13). Peritoneal thickening (smooth, n = 5; nodular, n = 10) was noted in 15 patients (88%) and a cul-de-sac mass in 10 (59%). Lymphadenopathy was noted in five patients (29%) and calcification within the peritoneal mass in one (6%). Serum CA-125 level was elevated in all patients (168-63,300 U/mL).


CONCLUSIONS
Serous surface papillary carcinoma of the ovary should be suggested as a diagnosis in patients who have peritoneal carcinomatosis, relatively normal-sized ovaries, and a highly elevated serum CA-125 level.
