CTICasesUndifferentiated Pleural Sarcoma with Rib Destruction

Imaging findings
An initial chest radiograph in 2007 was called normal. In 2012, a radiograph showed subtle periosteal reaction and destruction of a rib. CT revealed an extensive lesion involving two contiguous ribs with periosteal reaction and permeation.
Key takeaways
The case highlights the subtlety of bone destruction on initial radiographs. The lesion was an undifferentiated sarcoma, which eventually led to brain metastases. Malignant pleural lesions like sarcomas or aggressive fibrous tumors can erode into bone, differentiating them from benign fibrous tumors.
