MRI characteristics of parosteal lipomas associated with the HMGA2-LPP fusion gene..     ///    The expression of HMGA2-LPP fusion transcripts was determined using the reverse transcription-polymerase chain reaction method.     ///    "Since the HMGA2-LPP fusion transcripts are exclusively detectable in benign mesenchymal tumors, testing HMGA2-LPP expression may be useful for differential diagnosis in cases of radiologically-suspected well-differentiated liposarcomas.. "    ///     The magnetic resonance (MR) characteristics of parosteal lipomas with the HMGA2-LPP fusion transcripts are described.
