Background. Giant cell tumor (GCT) is an uncommon primary bone neoplasm in pediatric patients. Plain radiograph of the affected area is the first diagnostic approach in most cases. Objective. To show radiographic features that could allow the radiologist to suspect the diagnosis of GCT through plain radiological study. Methods. Records from the National Bone Tumor File between 1959 and 1999 were retrospectively analyzed. Twenty-nine cases of patients under 20 years with biopsy proven diagnosis of GCT were found. The radiological study was available in 14 cases. Results. From a total of 29 patients, 83% were females and 17% males. Age ranged from 7 to 19 years, with an average of 16.3 years. In cases with radiological study, 93% of them presented epiphyseal involvement of long bones. Osteolytic lesions with metaphyseal extension were the most frequent radiological pattern. One case showed malignancy with metastases. Conclusions. GCT is regarded as an infrequent occurrence in pediatric patients and its diagnosis can be suspected based on plain radiographic findings.
