MRI demonstrating a large cystic mass in the anterior mediastinum (white arrows), a cystic lesion in the left axilla (grey arrow), as well as numerous bone and splenic lesions (white arrowheads). Axial and Sagittal T1 fat-saturated images prior to administration of gadolinium (A, B) and post-injection of gadolinium (C, D) demonstrate no features of enhancement of the mediastinal mass. Axial HASTE fat-saturated sequence (E), sagittal STIR (F), and axial T2 fat-saturated sequence (G) demonstrate cystic nature of mediastinal mass, axillary mass, and multiple hyperintense bone lesions involving the vertebra and iliac bones. H Axial HASTE fatsaturated sequence of the upper abdomen illustrates numerous small splenic hyperintense lesions (black arrows)
