ABSTRACT

An aneurysmal bone cyst of fourth metacarpal which occurred in a 7-year-old girl was explored by MRI. MRI findings such as fluid-fluid levels were compared to literature. These levels are inconstant and not pathognomonic of aneurysmal bone cyst. They could occur within others bone tumors. Even if fluid-fluid levels are highly suggestive of aneurysmal bone cyst only pathological study asserts the diagnosis. MRI procedure might be a good procedure for post surgery follow up.
