Abstract
Intrasplenic metastases from ovarian carcinoma cannot be always demonstrated intraoperatively. CT is the most important imaging modality of choice for staging and follow-up ovarian cancer; in this study we searched CT appearances of intrasplenic metastases from ovarian carcinoma. We retrospectively reviewed imaging histories of the patients with ovarian cancer from the radiology information system, and found 12 patients with intrasplenic metastasis. All patients underwent abdominal CT with 16-MDCT. We searched number, density and maximum diameters of splenic metastasis. The growing rate of three lesions, which were followed up by CT, was calculated. Serum cancer antigen (CA) 125 levels were noted. We also evaluated clinical history and pathology reports of all patients. Splenic metastases, solitary or multiple, were detected most frequently during the follow-up (1-14 years after initial diagnosis) and most were associated with other sites of recurrence. The diameters of lesions ranged from 4 to 85 mm. All lesions appeared hypodense except for one lesion with dense calcification. Densities of lesions ranged from 12 to 208 Hounsfield units (mean, 49 +/- 51 HU). Most lesions appeared as solid well-defined nodules; however some lesions had lobulated and irregular contours with an infiltrative pattern. The growing rates of three lesions were 0.72 mm/month, 1.75 mm/month and 2.70 mm/month. Eight patients had elevated serum CA 125 levels (40-1256 U/mL). We concluded that CT can demonstrate intraparenchymal and infiltrative splenic metastasis in patients with ovarian cancer even in the absence of increased CA 125 levels.
