The craziness of the past week has settled down and #Breastradpath with @LizaMQuintana is back with Case 4!
53 yo had a screening MG. Maybe some new calcs or distortion in rt breast (arrow, 3D not shown)? #radres #radfellows -which images would you want during diag work-up??
She returned for diag work-up. Common diag w/u is mag views for calcs and tomo spots/90 for poss AD. But we decided to start with #contrastmammo & use enhancement to triage. What do you think? Based on these images alone, does it change your level of concern???? Ddx??
Rather than showing you other diag images, which weren't that helpful, I'm showing the US. Could this be a correlate??? Does it change your level of concern?? Ddx??
Share thoughts below.... more to come tomorrow!
We thought the US was a fine correlate & decided to recommend US-guided bx. We coded the case BI-RADS 4B bc our Ddx included PASH or ILC (was super similar to Case 2 in our series). The clip correlated perfectly with the enhancement. Check out Case 2 👇
Representative path slides are included. Hey there #breastpath what do you think??? Share your thoughts below!
Nice job everyone! Turns out this case was NOT pash (like Case 2) but actually was ILC with histiocytoid features. You all got it right!
Normal stroma is on the left and the ILC is on the right. Notice how many more nuclei there are in the ILC (blue dots) indicating way more cells. They are also extending outside the lobule. The # of cells and growth pattern are how we know it's invasive lobular
Here is an example of lobular neoplasia-many more cells but they are confined to the acinus of the lobule. Atypical lobular hyperplasia (ALH) & Lobular carcinoma (LCIS) are differentiated based on # of cells in acinus. More cells = LCIS, a non-obligate precursor to ILC.

Teaching points and relevant articles to come in the next few days...
This week's topic was invasive lobular cancer. Check out teaching points and articles below!
Here are the radiology teaching points. #radres #radfellows - did you know that ILC and PASH are both part of the differential for developing asymmetry??
Great Radiographics article on ILC:
