Multiorgan metastatic invasive lobular Carcinoma initially presenting as diplopia

We present an interesting case of biopsy-proven multiorgan metastatic invasive lobular carcinoma to the orbits and kidney, initially presenting in a 76-year-old woman with diplopia. Invasive lobular carcinoma is a less common subtype of breast cancer and is often difficult to detect on imaging with an unusual metastatic pattern when compared to invasive ductal carcinoma. Metastatic invasive lobular carcinoma most frequently involves the orbits, ovaries, gastrointestinal tract, retroperitoneum and bone. Disease involving these organ systems detected on imaging should raise concern for metastatic disease when appropriate.
