what are we trying to accomplish here?
- The first thing to realize is that pretty much no matter what, a 9 cm mass is going to be excised, so our job is to make our best educated guess as to the etiology so that the best surgical approach can be planned
how to approach a mass like this
- When you see a mass, the first thing you should try to ascertain is whether or not it is unilocular
- If unilocular, it is overwhelmingly likely to be benign.
- When faced with a unilocular mass with low amplitude echoes, the primary differential is neoplasm (prob benign vs. endomtrioma)
- Search hard for echogenic wall reflectors (if you see these, it is 47 times more likely to be endometrioma)
- If still unsure, MRI can definitively characterize the lesion as an endometrioma
