Spine osteoid osteoma and osteoblastoma in children: diagnosis and surgical treatment

The experience of diagnosis and surgical treatment of spine osteoid osteoma and osteoblastoma in 60 patients was presented. In 78% of cases osteoid osteoma was diagnosed before operation, in 36% of cases by X-ray examination, and in 86 % of all patients examined by CT method. Osteoblastoma was diagnosed by clinical examination in 8% of cases, and by CT method in 80% of the examined patients. By morphologic criteria noninvasive osteoblastoma (osteoid osteoma) 33 observations, invasive one 23 observations, malignant (agressive) 2 observations, multifocal one 2 observations were differentiated. The conclusion was drawn that there were various types of single pathologic process, i.e. osteoblastoma. Surgical treatment tumor resection together with surrounding zone of sclerosis, gave the recovery in 95% of cases. Three patients with tumor recurrence refused reoperation, their outcomes were unknown.
