Multiple Low Energy Long Bone Fractures in the Setting of Rothmund-Thomson Syndrome

Figure 8

Young adult male with history of Rothmund-Thomson syndrome diagnosed at 2 years of age. Findings: (a) recurrent mildly displaced right tibia diaphyseal fracture (arrow) with mild associated bone marrow edema and adjacent soft tissue edema. (b) Cortical thickening is present at the fracture site (arrow). There is no mass-like bone lesion identified, and normal fatty marrow signal extends almost to the fracture line. (c) Mild bone marrow and periosteal enhancement is present at the fracture site (arrow). No nodular or mass-like enhancement is present. Technique: (a) coronal STIR MRI (TR = 6350, TE = 44.5), ST = 5 mm, spacing = 6 mm, FOV = 38.0 × 44.8 cm, and matrix = 224 × 320; (b) coronal T1 MRI (TR = 650, TE = 13.2), ST = 5 mm, spacing= 6 mm, FOV = 38.0 × 44.8 cm, and matrix = 224 × 352; (c) coronal T1 postcontrast fat-saturated MRI (TR = 650, TE = 12.3), ST = 5 mm, spacing = 6 mm, FOV = 38.0 × 44.8 cm, matrix 224 × 320, and contrast = 13 mL, Magnevist.
