Cystic Angiomatosis of Bone (Report of Two Cases)

Cystic Angiomatosis of bone is a rare disease presenting as multiple cystic honey comb-like lesions, involving axial and appendicular skeleton. Lesion size varies from millimeters to several centimeters. The cysts have discrete sclerotic borders and their centers are radiolucent. The inner wall of the cysts are covered with endothelial cells and cysts are tilled with gelatinous or bloody liquid. Soft tissues or viscera may be involved too. When bone alone is involved, the prognosis is benign, but whenever simultaneous viscera involvement is present, the disease would be progressive, with poor prognosis. This is a report of two cases of cystic angiomatosis.
