ABSTRACT

Osteoid osteoma is type of benign bone tumor, characterized by a well-demarcated core with a typical size of <1 cm and by a distinctive surrounding zone of reactive bone formation. The tumor can occur anywhere in the cortex or medulla of the skeleton. However, the lesion usually affects the long bones of the lower extremities. The present study describes two cases of osteoid osteomas located in the rib.

f7-ol-09-04-1857: Computed tomography revealing the location of the lesion at the top of sixth right rib.

Mentions: In February 2011, a 16 year-old female was admitted to the Beijing Jishuitan Hospital. The patient presented with back pain that had been apparent for six months. A slight curve towards the left side of the patient’s back was observed. The patient complained of pain at night that was reduced by taking aspirin. A fixed tenderness point was identified in close proximity to the spine. A CT scan revealed a lesion that was located at the top of the sixth right rib with calcification present in the center (Fig. 7), while an X-ray scan revealed scoliosis of the thoracic spine (Fig. 8). An intra-operative three dimensional C-arm-based navigation system (REF 7700-500-000, Stryker, Kalamazoo, MI, USA) was used to locate and completely resect the tumor and curette the nidus (Fig. 9). The diagnosis was confirmed by histological analysis, which revealed interconnected, ossified bone trabeculae with abundant osteoblasts (Fig. 10; stain, hematoxylin and eosin, Tianhe Lien Company, Beijing, China). At the time of writing, the patient remained tumor-free.
