Purpose: Though it has been stated that hamartomas are rare tumours, radiologists frequently encounter it in their daily practice. Fat, glandular and fibrous tissues produce a mass of disorganized but mature specialized cells. Since hamartomas do not have specific diagnostic histological features, the clinical and radiological correlation is important in diagnosis. The aim of this study is to present the advanced magnetic resonance imaging findings of breast hamartomas. Materials and Methods: Eight patients with a breast hamartoma were examined in view of advanced magnetic resonance imaging findings in addition to ultrasonographic and/or mammographic findings. Results: All of the lesions showed gradual enhancement pattern in time-signal intensity curve on dynamic contrast enhanced magnetic resonance imaging (DCE-MRI). On MR spectroscopy (MRS), water and lipid peaks were detected similar to normal breast tissue. The diffusion features of the lesions were variable due to the different ratios of the tissue elements constituting them on diffusion-weighted imaging (DWI). Conclusion: Advanced MRI findings may be clarify the diagnosis by providing additional information to sonography especially in lactating or pregnant women, in whom mammographic examination is not preferred.
