Sonographic detection of early gallbladder cancer

During routine abdominal sonography and in cases of 'normal' gallbladder symptomatology, the sonographer may encounter an unsuspected early gallbladder cancer. 1 case report is presented in which a patient previously known with gallbladder concrements developed a primary gallbladder carcinoma within a period of 1 1/2 years. The clinical, pathological and prognostic features are discussed.
