title: 'Sabre sheath' trachea with mediastinal lipomatosis mimicking a mediastinal tumour.
abstract: Two cases of 'sabre sheath' trachea in combination with mediastinal lipomatosis are reported. The initial chest radiographs in both cases were interpreted as showing a mediastinal tumour causing tracheal compression. The correct diagnosis was subsequently made using computed tomography (CT). It is important to be aware of these benign conditions when interpreting chest radiographs, particularly in cases of suspected mediastinal pathology.
