ULTRASONICALLY GUIDED ASPIRATION BIOPSY IN OSTEOLYTIC BONE-LESIONS OF THE CHEST-WALL

Sixteen consecutive patients with one or more osteolytic bone lesions of the chest wall radiologically confirmed underwent ultrasonically guided aspiration biopsy. Nine patients (56.2 percent) had bronchogenic carcinoma with a direct extension. Other diagnostic techniques had failed to diagnose disease in these patients. The lesion showed heterogeneous echogenicity (n = 16) caused by the hyperechoic signals of bone fragments. The interruption of the cortex bone was detected in all cases and extraosseous tumor portion in 14 of 16 patients (87.5 percent). No respiratory motions of the lesion could be demonstrated (n = 16). Definitive histologic diagnosis was made in 14 of the 16 patients (87.5 percent). In malignancy, diagnosis was established in 13 of 14 patients (92.8 percent). Of two confirmed benign lesions, one diagnosis of tuberculosis was obtained. No complication occurred. Sonography and consequently ultrasonically guided aspiration biopsy are a useful, accurate, safe, and low-cost technique for osteolytic lesions in thoracic diseases.
