Solidified mucinous tumor of the ovary presenting characteristic MRI finding Junichi Matsumoto, Kotaro Yoshida, Dai Inoue, Norihide Yoneda, Hiroko Ikeda, Yasunari Mizumoto, Toshifumi Gabata European Journal of Radiology Open Volume 6, Pages 68-71 (January 2019) DOI: 10.1016/j.ejro.2019.01.005 Copyright © 2019 The Authors Terms and Conditions

Fig. 1 Ultrasonography (US). US showed a well-circumscribed hypoechoic mass, with spotty hyperechoic lesions, 70 mm in diameter. European Journal of Radiology Open 2019 6, 68-71DOI: (10.1016/j.ejro.2019.01.005) Copyright © 2019 The Authors Terms and Conditions

Fig. 2 Magnetic resonance (MR) imaging. a) The mass showed heterogeneous hyperintensity on T1-weighted MR images (repetition time [TR]/effective echo time [TE], 300/2.4 ms). b) T2-weighted images demonstrated hypointense mass with hyperintense reticular structures (TR/TE, 4267/91 ms). A unilocular cyst was also present in the mass. c) Contrast-enhanced MR images with fat-saturation showed slight reticular enhancement (TR/TE, 4.2/2.0 ms). d) Apparent diffusion coefficient value of the tumor was 1.38 × 10−3 mm2/s (TR/TE, 4800/64 ms, b-value = 800 s/mm2).

Fig. 3 Unenhanced CT. On unenhanced CT, the tumor demonstrated heterogeneous hyper-attenuated. European Journal of Radiology Open 2019 6, 68-71DOI: (10.1016/j.ejro.2019.01.005) Copyright © 2019 The Authors Terms and Conditions

Fig. 4 Photograph of cut surface of ovarian tumor. The cut surface of the mass showed multiple whitish firm gelatinous texture deposition with septa. European Journal of Radiology Open 2019 6, 68-71DOI: (10.1016/j.ejro.2019.01.005) Copyright © 2019 The Authors Terms and Conditions

Fig. 5 Histopathological finding of surgical specimen (Macrograph and magnified image). a) On Macrograph of resected specimen, the gelatinous portion consisted of degenerated mucin. b) On the septal structure, papillary cell proliferation, pseudostratified epithelium pattern and nuclear enlargement were observed in some areas.
