Ovarian mucinous tumours

Radswiki et al.

Ovarian mucinous tumours are a subgroup of ovarian epithelial tumours. They represent ~20% of all ovarian tumours and ~10% of all malignant ovarian tumours. 

Subtypes

Mucinous ovarian tumours can be broadly sub-classified into three main subgroups:

General

In general, the cell type (e.g. serous, mucinous) often cannot be determined by the appearance at MR imaging, CT, or ultrasound 5

While some of the specific features can vary between the subtypes, there are certain features which are more common among mucinous tumours: 3

  • often larger than their serous counterparts (on occasion they may be enormous)
  • tend to be more multilocular with small cystic components +/- honeycomb-like locules
  • calcification is comparatively rare and if present tends to be linear
  • bilaterality is comparatively rare
  • peritoneal carcinomatosis is less common compared with serous tumours
  • may have accompanying pseudomyxoma peritonei
MRI
  • T1
    • the signal intensity of mucin on T1-weighted images varies depending on the degree of mucin concentration
    • on T1-weighted images, loculi with watery mucin have a lower signal intensity than loculi with thicker mucin. 
  • T2
    • on T2-weighted images, the corresponding signal intensities are flipped, so that loculi with watery mucin have high signal intensity and loculi with thicker mucin appear slightly hypointense.

Prognosis of mucinous tumours is highly dependent on stage and histologic composition: see individual subtypes
