Sclerotic variant of lymphangiomatosis of bone: imaging findings at diagnosis and long-term follow-up.

Lymphangiomatosis is an extremely rare congenital disorder affecting visceral organs and/or the skeletal system. In bone is is usually characterized by multiple lytic lesions with a lacelike pattern and sclerotic margins of various thickness. In this case report we demonstrate the rare sclerotic variant of lymphangiomatosis. We report the development of predominantly sclerotic lesions at different sites by serial radiographs with a long-term follow-up, and show the MRI findings of lymphangiomatosis of the spine.
