The clinical, roentgenologic and pathologic features in nine patients with cervicomediastinal cystic hygroma seen at the Mayo Clinic have been presented, bringing the total number of reported cases to 37.
These lesions are congenital tumors of lymphatic origin, and they are loculated and extensive. Despite their histologically benign character, they have an infiltrative type of growth that makes their surgical removal difficult. Malignant degeneration has not been known to occur.
The presence of a cervical mass and the frequent evidence of compression of vital structures in the neck and upper mediastinum cause these lesions to be recognized in the early years of life. They are less common in adults.
Surgical removal is the ideal treatment. When this is not possible, roentgen therapy is effective in some instances in controlling the growth of the tumor.
