Objective: This study aimed to describe the magnetic resonance imaging (MRI) features of pure breast encapsulated papillary carcinoma (EPC).
Materials and methods: Ten patients with histopathologically confirmed breast pure EPC were reviewed. Two radiologists evaluated lesion MRI characteristics.
Results: The EPC presented oval or round mass with circumscribed margin on MRI. In addition, 4 cases exhibited a cystic-solid mixed mass with mural nodules, and 4 cases exhibited a liquid level that indicated the possibility of hemorrhage.
Conclusions: A well-defined cystic-solid mixed mass with mural nodules, or a circumscribed mass exhibiting the possibility of hemorrhage, may suggest the diagnosis of EPC.
