Breast MRI background parenchymal enhancement as an imaging bridge to molecular cancer sub-type.

Purpose: To evaluate the distribution of MRI breast parenchymal enhancement (BPE) among different breast cancer subtypes searching for any significant difference in terms of immunohistochemical and receptorial patterns (Estrogen Receptor -ER, Progesterone Receptor - PR, Human Epidermal Growth Factor Receptor 2 - HER2).

Methods: 82 consecutive patients affected by breast cancer underwent breast DCE-MRI. Two radiologists retrospectively evaluated all subtracted MR enhanced images for classifying BPE.

Uremic lung: The "calcified cauliflower" sign in the end stage renal disease.

Metastatic pulmonary calcification (MPC) is a rare pathological condition consisting of lung calcium salt deposits which commonly occurs in patients affected by chronic kidney disease probably for some abnormalities in calcium and phosphate metabolism. CT represents the technique of choice for detecting MPC findings including ground glass opacities and partially calcified nodules or consolidations. We present a case of MCP in a patient affected by hepato-renal autosomic-dominant polycystic disease; chest CT revealed extensive lobar-segmental parenchymal calcification with a peculiar cauliflower shape which we called "calcified cauliflower" sign.

Management of castrate resistant prostate cancer-recent advances and optimal sequence of treatments.

Until 2010, chemotherapy with docetaxel was the only approved agent for treatment of metastatic castrate resistant prostate cancer (mCRPC). Since then, the therapeutic landscape of mCRPC has changed rapidly. Multiple novel agents have received regulatory approval after demonstrating improved overall survival in separate randomized Phase 3 studies.
