MALIGNANT NEUROECTODERMAL TUMOR OF THE CHEST-WALL (ASKIN TUMOR) - CT AND MR FINDINGS IN 8 PATIENTS

Malignant neuroectodermal tumour of the chest wall (Askin tumour) is an uncommon malignant neoplasm affecting young adults. We retrospectively reviewed the clinical and pathological information and radiologic studies in our archives on eight cases of this tumour. All cases were pathologically proven. Plain films, CT scans and radionuclide images were available in all cases. MR images were also available in two patients. Although rare, Askin tumour should be included in the differential diagnosis when a chest wall or thoracic paraspinal mass is identified in a young individual.
