[Chance coincidence of spondylolisthesis and osteoid osteoma of the spine--a case report].
ABSTRACT Between 10 and 20% of all osteoid osteomas are located in the spine. Diagnosis is often hampered by atypical signs and symptoms and unclear X-rays. Striking (chance) X-ray findings in this case, a spondylolisthesis- can divert attention away from a correct diagnosis. Scintiscanning and computer tomography are essential for a correct diagnosis.
