  		Fig 1. A 31-year-old man with known generalized lymphangiomatosis presents with right proptosis.

A, Coronal fat-suppressed T2-weighted MR image demonstrates bilateral extramuscular hyperintense lesions. Additional masses with similar signal intensities are noted in the masticator spaces.

B, Low T1 signal intensity in these lesions without contract enhancement.

C, Coronal T2-weighted MR image demonstrates high-signal-intensity lesions in the occipital condyles and upper cervical vertebrae.

  		Fig 2. A 28-year-old man presents with a mediastinal mass on a chest x-ray for further work-up.

A, Axial contrast-enhanced CT scan of the chest demonstrates multiple nonenhancing cystic lesions in the mediastinum.

B, Axial contrast-enhanced CT scan of the neck at the level of the orbits demonstrates bilateral nonenhancing retrobulbar low-attenuation lesions.

C, Axial contrast-enhanced CT scan of the neck viewed at bone window settings demonstrates multiple lytic lesions of the occiput and upper cervical vertebrae.

D, Axial contrast-enhanced CT scan of the abdomen demonstrates multiple nonenhancing cystic lesions in the peritoneum.
