if there are no signs of infection, a cyst of montgomery can be observed, because more than 80% resolve spontaneously, over only a few months. however, in some cases, spontaneous resolution may take up two years. in such cases, a repeat ultrasonography may become necessary. if, however, the patient has signs of an infection, for example reddening (erythema), warmth, pain and tenderness, a treatment for mastitis can be initiated, which may include antibiotics and non-steroidal anti-inflammatory drugs (nsaids). with treatment, inflammatory changes usually disappear quickly. in rare cases, drainage may become necessary. a surgical treatment of a cyst of montgomery, i.e. a resection, may become necessary only if a cyst of montgomery persists, or the diagnosis is questioned clinically.
