Abstract
|
|
|
An accurate diagnosis of the bone tumors on the basis of its radiographic characteristics is not possibile. However, the precise morphology of a lesion does provide reliable information regarding its "aggressiveness" or rate of growth, and this information coupled with data reflecting the site of the lesion, the age of the patient and matrix patterns allows the formulation of a resonable diagnosis in most cases.
A total of 79 cases of benign bone tumors were reviewed and analyzed clinically, radiologically and pathologically at the department of radiology and Nuclear Medicine, Yonsei University during the 5 years period from January, 1976 to December, 1980.
The results were obtained as follows:
1. Osteochondroma was the most common benign bone tumor and followed by osteoma, enchondroma, simple bone cyst and osteoid osteoma.
2. Male to Femal sex ratio was 1.4 : 1. Incidence was most commoon in 2nd & 3rd decade as 76%.
3. Enchondromas are located in the small bones of the hand in 8 cases among 9. Osteoid osteoma appeared in tibia (6 cases among 8). Osteoma predominated in skull and frontal sinuses.
4. Chondroblastoma showed epiphyseal location in 2 cases among 3 and osteoid osteoma involved cortical aerea of tibia shaft in 7 cases. Simple bone cyst showed central location in metaphysis of femur or humerus.
5. Enchondroma showed ring, stippled or arc shaped calification in 4 cases among 9. Osteochondroma showed calcification patterns in 4 cases among 31. 2cases of osteoblatoma showed ossification pattern.
6. 64 cases of bening bone tumors showed well defined margins and 20 cases showed sclerotic border.
