Ovarian carcinoma metastases on CT and MRI

(A) A CT scan through the upper abdomen shows an indeterminate lesion in the spleen (arrow) in a patient with ovarian carcinoma.
(B) A T2-weighted image shows a cystic center (arrowhead) and a thick solid rim (arrow) consistent with an isolated metastasis.
(C) A CT scan performed four months later shows a growing splenic nodule (arrow) and new ascites (arrowhead).
