Pulmonary Metastases from Chondroblastic Osteosarcoma

Magnetic resonance imaging of the appropriate leg disclosed a large, enhancing, circumferential periosteal femoral mass that measured 30 cm in the craniocaudal dimension, as well as a nonocclusive thrombus in the appropriate femoral vein, for which the client obtained anticoagulation.

A 21-year-old woman offered to the emergency division with an 8-month background of dynamic swelling as well as pain in the appropriate upper leg.

Biopsy of the femoral mass validated a medical diagnosis of chondroblastic osteosarcoma.

One week later, the client had lack of breath and also left pleuritic upper body discomfort.

The oxygen saturation was 94% while the individual was breathing ambient air. Upper body radiography revealed numerous sores in both lungs (Panel A). Calculated tomography of the chest verified the presence of extensive, lobulated, and also partly calcified nodules and masses throughout both lungs, a searching for suggestive of pulmonary metastases (Panel B).

In spite of the initiation of chemotherapy, the illness progressed. A second chemotherapy routine was started; 5 cycles have actually been completed, and the illness is presently stable.
