XXXX : CT and MR findings.

@entity1 @entity5 @entity10968 @entity730 @entity8940
PURPOSE: The purpose of this study was to determine the CT and MR characteristics of @entity5 , rare epithelial neoplasms of the ovary. METHOD: CT and MR scans of eight pathologically proven @entity5 of the ovary (seven benign, one malignant, and one associated with @entity8940 ) were retrospectively reviewed. The masses were analyzed for location, size, external configuration, internal architecture, enhancement pattern, presence of @entity730 , and metastatic spread. RESULTS: The @entity1 ' median age was 63 years (range 39-79 years), and the mean size of the @entity5 was 11.4 cm (7.5-17 cm). All @entity5 were unilateral and had a well-defined margin. The mass was mostly solid in three, mostly cystic in one, and "mixed" solid and cystic in four cases. The @entity5 with cystic components (n = 5) were mostly multilocular in appearance (n = 4). All the solid components showed mild homogeneous enhancement on postcontrast CT and MRI. Extensive amorphous @entity730 within the solid component on CT was seen in five of six cases (83%). No characteristic findings discriminating @entity10968 could be found. CONCLUSION: Extensive amorphous @entity730 in a solid mass or solid component in a multilocular cystic mass is a characteristic finding of @entity10968 and MRI.
