Breast cancer remains the leading cause of cancer related death in females worldwide. Metastatsis from breast primary are usually seen in lungs, bones and liver. Uncommon sites include adrenals, thyroid, spleen, pancreas and urinary bladder. Retroperitoneal metastasis are considered most unsual among breast cancer. We present the case of a treated breast cancer patient with a large reteroperitoneal lesion suggesting other aetiologies on imaging but proved to be metastasis on histopathology.
