@entity455 of bone and soft tissue are relatively common @entity85 . @entity2695 is the most frequently encountered @entity75 . @entity2695 commonly involves the spine and calvaria and often has a characteristic radiographic appearance, with either coarsened trabeculae lying adjacent to the vascular channels or multifocal lytic areas creating a honeycomb pattern. Soft-tissue @entity2695 is the most frequent soft-tissue @entity5 of infancy and childhood. Radiography and computed tomography (CT) may show phleboliths in cavernous soft-tissue @entity2695 . The magnetic resonance (MR) imaging appearance, however, is often more distinctive, because fat overgrowth and @entity9155 vascular channels can be seen. Lymphangioma usually occurs in the neck and axillae of young @entity1 as a soft-tissue mass composed of large cavernous spaces and is well evaluated with CT, ultrasound, or MR imaging. @entity455 can also diffusely involve both bone and soft tissue in @entity4904 . A group of @entity146 , including @entity8146 , @entity2698 , and @entity5426 , may have a nonspecific imaging appearance; however, the vascular pattern can be recognized in some cases, allowing radiologic diagnosis. Imaging is important throughout the evaluation of @entity75 for detection, diagnosis, preoperative assessment, and treatment.
