INTRODUCTION
As a subtype of biliary tumors, gallbladder cancer is rare yet highly
malignant1. Characterized by its ease of metastasis
and poor prognosis, its common sites of metastasis include lymph nodes
and the liver. However, it can also spread to other organs and tissues
such as the lungs, bones, and peritoneum2. It’s
critical to note that the incidence of lung metastasis in gallbladder
carcinoma hovers around 10-30%, with a dismal 5-year survival rate of
around 5-10%3-4. Unusually, when gallbladder
carcinoma metastasizes to the lungs, it can sometimes present as
pulmonary cavitary lesions, although this manifestation is not commonly
observed. In this light, we present a case of gallbladder carcinoma with
pulmonary manifestations of cavitary lesions.
