| Percutaneous biopsy of bone lesion is usually performed under the guide of fluoroscopy or CT. Howeverultrasound (US) guided biopsy of bone lesion has seldom reported. We studied the usefulness of US guided biopsy ofvarious bone lesions. We performed the US guided biopsy of various bone lesions in 14 patients (13 male, 1female). Biopsy site was in rib in 2, clavicle in 3, humerus in 3, ileum in 3 and femur in 3 patients. Before thebiopsy, we examined the bone lesion with US and anesthesized the overlying skin and the soft tissue. When thedestructed cortex and soft tissue lesion was found, we performed US guided aspiration or tissue biopsy with 21Gspinal needle or the Tru-cut needle. When the cortical defect or soft tissue lesion could not be found, biopsy wasdone with 15G Ostycut needle. In 13 (93%) of total 14 cases, we could obtain sufficient aspirate or tissue for thepathologic examination. During our early experience, we failed to obtain adequate tissue in one case withplasmacytoma. The biopsy material was proved as pyogenic bone abscess in 1, tuberculous osteomyelitis in 2,primary bone tumor in 3 and metastatic bone tumor in 7. In conclusion, US guided biopsy of bone lesion is safe,useful, and accurate method in the preoperative tissue diagnosis and staging of metastatic bone tumor, primarybone tumor and infectious bone disease. It is particularily valuable as it is performed without radiation. |
