Bilateral pleural effusion, small amount of free abdominal fluid and inflammatory area on right inferior fossa. Images show inflammatory area with free fluid and a markedly thickened and irregular of caecal walls.
Caecal carcinoma can clinically mimic acute appendicitis, either by presenting as a painful mass or secondary to perforation.
In this case we can see an exuberant inflammatory inflammatory process with free fluid on caecum region. These, with the clinical history, can suggest us for an acute appendicitis, but the history of previous appendicectomy and the markedly thickened and irregular caecal walls show us a caecal tumour.
Colorectal carcinoma is the most common cancer of the gastrointestinal tract and the second most frequently diagnosed malignancy in adults.
