IDC with Lobular Invasion Pattern vs. ILC?

I was diagnosed with "invasive ductal carcinoma of no special type with lobular invasion pattern" (Stage 1, Grade 2, ER+ PR+, HER2 -, Oncotype score 6). What is the difference between ILC and "lobular invasion pattern"? I have found differing descriptions, and I know that the pattern was enough to get the oncologist to prescribe an additional boost at the end of radiation, but I still am unclear as to the difference between this and ILC. Do I have both? Thank you!
