Hemorrhagic Cysts and
Tricks for Differentiating Neoplastic
From Benign Features
Significance of hemorrhage into a unilocular lesion
- If we see this and truly know that it is hemorrhagic, then we can be highly confident that we are looking at a benign lesion.
Mural nodules vs. adherent clot
Fibrin strands vs. septations
- No fool proof method for determining, so stay cautious
- Fibrin strands within a hemorrhagic cyst tend to me much more numerous. Often >30 per image. A neoplasm could have 30+ septations, but that's through the whole mass rather than on a single still image
- Septations within a neoplasm tend to "flow into one another" where as fibrinous stranding is more of a random process.
