  A Radiologist’s Guide to Mammography, Ultrasound, Core Biopsy, and AI-Assisted Interpretation A 37-year-old woman with a painless palpable breast mass demonstrates the central diagnostic dilemma of diabetic mastopathy: a benign fibro-inflammatory process that can reproduce the clinical and imaging phenotype of breast cancer. When a Firm Breast Mass Looks Like Cancer A 37-year-old woman undergoing a routine health examination was found to have a firm mass in the right breast. There was no pain. No tenderness. No obvious skin change. The clinical history, however, contained an important clue: she had long-standing type 2 diabetes and obesity. She had also given birth six months earlier and had breastfed. Mammography showed very dense breast tissue and architectural distortion at the site corresponding to the palpable abnormality. Targeted ultrasound revealed an approximately 10-mm irregular hypoechoic mass, accompanied by another similar lesion measuring approximately 6 mm nearby....

1. Clinical Hook A 73-year-old man with colorectal malignancy presents an imaging problem that is more complicated than simply identifying a primary tumor. The critical question is not merely: “Where is the cancer?” It is: “How far has the cancer traveled, by which route, and does that pattern change management?” That distinction is fundamental in advanced colorectal cancer. The supplied case material describes metastatic disease and contiguous spread through several possible pathways, including direct extension, lymphatic dissemination, peritoneal spread, fascial-plane extension, and hematogenous dissemination. The imaging set illustrates why no single modality can answer every clinical question. Contrast-enhanced CT provides the broad anatomic map. MRI contributes superior soft-tissue characterization, particularly in the pelvis. FDG-PET/CT identifies metabolically active disease. Ultrasound can detect selected hepatic lesions and support bedside assessment. Colonoscopy directly visu...
