Abstract: (8900 Views) |
| Osteoid osteoma (OO) is a relatively common
skeletal neoplasm, frequently involves long bones.
OO of rib is extremely rare, including 0.23-2% of OO
cases. Most of them arose in posterior arc,
frequently in its head or neck and might lead to
painful scoliosis. Involvement of anterior aspect of a
rib is extremely rare. Skeletal scintigraphy is highly
sensitive for detection of OO. “Double density sign" a
typical pattern in bone scintigraphy is usually seen in
OO of cortical bones. The current study presents a
case of 22-year-old man with OO in anterior arc of a
rib, revealed double density sign on 99mTc-MDP
scan. Iran. J. Radiat. Res., 2012 10(3‐4): 197‐199
