When the lesions are small, they are often asymptomatic and most are found during a physical examination. In larger lesions, pain in the upper right abdomen may occur, and compression of the bile ducts may result in jaundice, while compression of the intestinal ducts may affect gastrointestinal function, resulting in paroxysmal pain and loss of appetite. The lesion is co-infected and symptoms such as chills and high fever may occur.
