Solitary Osseous Metastasis of Rectal Carcinoma Masquerading as Osteogenic Sarcoma on Post-Chemotherapy Imaging: A Case Report

Solitary metastases from colorectal carcinoma in the absence of hepatic or pulmonary metastases are rare. These can have a diverse imaging appearance, particularly after chemotherapy. It is important identify patients with solitary skeletal metastases, as they have a better prognosis than those with multiple skeletal or visceral metastases. We describe an unusual case of a solitary metastasis to the femur in a case of colon carcinoma that went undiagnosed and later presented with imaging features of osteogenic sarcoma.

Diagnosis of a Malignant Intramammary Node Retrospectively Aided by Mastectomy Specimen MRI-Is the Search Worth It? A Case Report and Review of Current Literature

Metastases to intramammary nodes have been shown to be an independent predictor of poor outcome in patients with breast cancer, such as axillary lymph node metastases. The detection and accurate characterization of these nodes preoperatively is thus crucial for the staging and planning of treatment for breast carcinoma, particularly in cases with axillary lymph node negative disease as it upgrades the disease staging. We herein report the first case where we detected an intra-mammary node on specimen MRI after the primary pathological gross specimen evaluation failed to detect the node.
