title: [Cystic lesion of the calcaneus. Intraosseous lipoma].
abstract: We report two cases of intraosseous lipoma in the calcaneus of a 38 year old man, complaining about heel pain and a 27 year old woman with no pain. Plain radiographs showed a well-defined cystic lesion in the calcaneus with sclerotic margins. Computed tomography (CT) detected a well-defined, low-density lesion with attenuation values equal to adipose tissue. Magnetic resonance (MR) findings show similar signal intensity with subcutaneous adipose tissue on T1-weighted and T2-weighted images, and STIR-T2 imaging showing low signal intensity with complete suppression indicating the presence of normal fat. As a result, at first intraosseous lipomas could only be identified pathologically, but now it is easy to perform radiological diagnosis using MR.
