Polycystic hydatidosis: casual finding of calcified hydatid cyst simulating mesenteric neoplasm

A case of abdominal hydatidosis, without hepatic involvement, in a patient from the State of Acre is reported. The hydatid, already in degeneration and partially calcified, was discovered incidentally by a radiologic examination of the vertebral column, carried out for evaluating the state of an intervertebral disk prolapse. Although the images suggested a mesenteric tumor, attached to the intestinal wall, the finding of rostellar hooklets in the dense contents of the cyst, after surgical removal, revealed the parasitic nature of the lesion.
