Case of the Week: Ovarian Mucinous Cystadenocarcinoma (Ultrasound & MRI)

- เผยแพร่เมื่อ 3 ก.ค. 2024
- In this radiology lecture, we reveal the imaging appearance of mucinous cystadenocarcinoma of the ovary and explain differentiating features from serous cystadenocarcinoma.
Key points include:
1) A rare type of malignant ovarian epithelial tumor.
2) Often large at presentation, may be enormous.
3) Almost always multilocular.
4) Mucinous, proteinaceous and hemorrhagic material within loculi.
5) US: Scattered low-level echoes.
6) MRI: “Stained glass” appearance = Variable T1/T2 signal. Thick mucin = T1/T2 hyperintense.
7) Irregular, thick septations and solid components with internal vascularity and enhancement allow differentiation from mucinous cystadenoma.

Very well explanation! Fantastic presentation!
Thank you so much! Really appreciate that :)
I really wish you were my radiologist. I’ve taken somewhere between 4 and 5 MRIs, a couple CT scans, and a couple ultrasounds for a 11x9 cm pelvic mass, all to finally receive a differential diagnosis of cystadenoma or adenocarcinoma. It scares me to death because the first couple of MRIs and ultrasounds concluded it as an ovarian cyst.
Lovely demo thank you :) In the UK (on USS) we would describe this adnexal lesion using IOTA terminology, as a large irregular multilocular-solid lesion (>10 locales) with strong vascularity and no shadowing.
Thank you very much for all the exceptional and generous teaching. A radiology résident in Sénégal.
You are very welcome, and good luck with residency Abakar Gori!
Always learn some great nonneuro cases from your excellent tutorials.
Great to hear!
Brilliant case as always. Fantastic presentation.
Thank you kindly! Appreciate the feedback :)
Thank you - great demonstration:)
In the UK we would (on USS) describe this using IOTA criteria - large irregular multilocular-solid lesion with >10 locules containing low level or mixed echogenicity, strong vascularity and no shadowing. You can then use Simple Rules or ADNEX to calculate the risk of malignancy. And use the ADNEX score to determine the O-RADS category.
Best wishes
Great tip thank you! I wish the IOTA criteria was used more frequently in the US, but at least we have O-RADS which adopts parts of it.
Thanks...God bless you
You're welcome and thank you!
Amazing description
Thank you!
Excellent teacher in world 😍
Thank you! 😃
What would you list for your differential in this case?
For the ultrasound images, I would probably include other epithelial tumors such as serous cystadenocarcinoma, endometrioid tumor, and clear cell tumor. However, the MRI appearance is more specific for mucinous tumor given the stained glass appearance on T1-weighted images, together with the multilocularity and large size of the mass, and would consider a mucinous cystadenocarcinoma or a borderline mucinous tumor.
I didnot understand this is the serous cystadenoma and mucinous cystadenoma differentation or serous cystadenocarcinoma and mucinous cystadenocarcinoma differentation ?? Please send me the answer
Carcinoma will have thickened septations and mural nodularity, sometimes also with metastatic disease and ascites.
Is MUCINOUS CYSTADENOCARCINOMA FIGO GRADE 1 ovary means malignant?
Yes, but it means that the cancer has not spread outside of the ovary.
But before the surgery the ovarian tumor ruptured already.what are the risk?would cancer cell spread faster to other lymph nodes and other organ?
Mucinous border line tumer with atopia only means sir?
