Mesenchymal hamartoma of the chest wall : radiologic manifestations with emphasis on cross-sectional imaging and histopathologic comparison
2002
PURPOSE: To describe the imaging features of chest wall mesenchymal hamartoma with emphasis on cross-sectional imaging and comparison with histopathologic results. MATERIALS AND METHODS: For 14 mesenchymal hamartomas of the chest wall in 12 children, radiologic studies (computed tomographic [CT] scans [n = 14], radiographs [n = 11], magnetic resonance [MR] images [n = 9], and bone scintigraphic images [n = 1]) were reviewed by four radiologists with consensus agreement. Clinical history was reviewed for patient demographics and symptoms at presentation. Radiologic studies were evaluated for lesion location, size, number of affected ribs, cortical irregularity or erosion, presence and type of matrix mineralization, lung hyperaeration adjacent to the lesion, degree and homogeneity of radionuclide uptake, and intrinsic characteristics on CT and MR images. RESULTS: Patients included seven male and five female children. Nine patients (75%) were younger than 1 year. Five patients had a chest wall mass; in the r...
