Peritoneal carcinomatosis is a severe condition characterized by the widespread dissemination of cancer cells within the peritoneum, the membrane lining the abdominal cavity and covering its organs. Originating from various primary cancers, such as ovarian, colorectal, or gastric malignancies, it often indicates advanced disease and presents a significant challenge in abdominal oncology. Ultrasound plays a crucial role in its diagnosis and management.
In medical ultrasound, peritoneal carcinomatosis typically appears as ascites (fluid accumulation), omental caking, or nodular thickening of the peritoneal surfaces. High-resolution imaging can detect even subtle peritoneal implants, guiding biopsies and staging. Early detection via abdominal ultrasound is vital for treatment planning, improving patient outcomes, and monitoring disease progression in this complex form of cancer.
