Mammographic manifestations of steatocystoma multiplex

Objective: To identify the typical imaging features of steatocystoma multiplex on mammography. Methods: Mammographic findings in 9 patients with clinical and pathological diagnosis of steatocystoma multiplex were analyzed along with a review of the current literature. Results: Four of the nine patients with steatocystoma multiplex had a positive family history. Nine patients showed multiple, round, thin-walled fatty, radiolucent nodules with well-defined margin. These nodules are located in the superficial layer of the axilla bilaterally. They are also seen on the skin of breast (7 eases), the anterior chest wall (4 cases) and the upper arm (3 cases). Conclusion: Recognition of the characteristic mammographic features of Steatocystoma multiplex is important in the management of these patients. (authors)
