Popis: Objective: Since ovarian borderline tumor with invasive implant behaves as carcinoma, it should be managed like carcinoma. Since its characteristic features have not been reported, its preoperative diagnosis was thought to be impossible. We evaluated the features of MRI and macroscopic appearance in two cases of ovarian borderline tumor with invasive implant. Methods: Borderline tumor with invasive implant was evaluated in two patients by MRI and macroscopic examination. Results: In these patients, MRI revealed profuse papillary projections. Although the lesion showed high signal intensity on contrast-enhanced T1-weighted images compared with that on T1-weighted ones, most of the signal intensity on T2-weighted images was high, suggesting that the lesion is an assembly of vesicles and an obvious solid part is absent. The macroscopic appearance of the tumor showed profuse papillary projections consisting of many vesicles perforating and extending far beyond the ovarian capsule, without a solid part. The histological findings indicated serous borderline tumors with invasive implant. Conclusion: In these two cases, we found the characteristic features of serous borderline tumor with invasive implant by MRI and macroscopic examination. Our findings may be of clinical value since the preoperative information about the possibility of invasive implant may be quite important for the management of borderline tumor with invasive implant, especially for young patients wishing to bear children.
