Different sizes of ribs on both sides can be seen in congenital developmental abnormality, rib fracture, rib tumor, local inflammation around ribs.
1. Congenital developmental abnormality: some patients have congenital developmental abnormality of ribs, resulting in one side being thick and the other side being thin, and the size of the ribs on the left and right sides looks different from the appearance, if there is no uncomfortable symptom, there is no need to have special treatment, but if the deformity affects the respiratory and circulatory functions, the deformity should be corrected by timely surgical treatment.
2. Rib fracture: If there is a history of trauma, rib fracture can be caused by trauma, and the rib fracture does not heal properly, thus the size of the left and right side of the rib cage is not the same.
3. Rib tumor: if there is no history of trauma, and the size of the lower part of the ribs is not the same on both sides, we can not exclude the possibility of having rib tumor, because the growth of the tumor will make one side of the ribs bigger, and we should go to the hospital in time for consultation.
4. Local inflammation around ribs: when there is inflammation and infection under one side of ribs, which leads to swelling on the affected side, the size of ribs on both sides will be different, usually accompanied by pain and pressure pain at the same time.
There are many reasons for the different sizes of the ribs on both sides, which should be analyzed together with the medical history and symptoms. It is recommended to consult a doctor in the hospital, and if necessary, take further relevant examinations such as radiographs, in order to make a clear diagnosis.
