Mathew Leonardi: Why Endometriosis Is Often Missed?
Dr. Mathew Leonardi, Associate Professor at McMaster University, shared a post on LinkedIn:
“Endometriosis does not have one single appearance, and that is part of why it is so often missed.
In this carousel, I’ve included a range of endometriosis lesions across different disease types and locations, including superficial disease, ovarian disease, and deep endometriosis involving areas such as the bowel, bladder, uterosacral ligaments, peritoneum, vagina, and ovary. A few are deliberately difficult because real-life recognition is not always straightforward.
As you go through the images, pause on each one and ask yourself:
What am I looking at?
What features make this location or lesion type recognizable?
What would make this easy to miss?
The final slide has the answers.
I’d love to know which image was hardest for you, or what area you are still trying to get better at identifying, whether that is ultrasound, surgery, anatomy, or lesion patterns.
If this kind of teaching is useful, save the post so you can come back to it, and share it with someone else learning endometriosis imaging or surgery. Comments, saves, and shares also help this reach more people who are trying to build real pattern recognition.”
