title: Lipid cyst: classic and atypical appearances.
abstract: Lipid cysts, a specific type of fat necrosis, frequently have a pathognomonic appearance on radiographs. This consists of a lucent lesion surrounded by a smooth rim that may or not be calcified. Occasionally, lipid cysts with unusual mammographic appearances are encountered. An appreciation of some of these appearances may prevent unnecessary biopsies.
