CHEST, ABDOMEN, AND PELVIS CT SCAN WITH IV & ORAL CONTRAST:
An oval-shaped ill-defined heterogeneous enhancing soft tissue mass lesion with areas of cystic degeneration and containing calcification is seen arising from the 11th rib antero- medially . It measures around eight by seven by three centimeters in dimensions. This lesion is consistent with Ewing’s sarcoma.
Periosteal reaction to the adjacent rib is also seen.
Both lung fields appear clear without evidence of metastasis.
Hila and mediastinum appear normal without evidence of lymphadenopathy or mass lesions.
The liver and spleen appear normal in size and homogenous without evidence of focal lesion.
Kidneys, adrenal glands, and pancreas appear normal without evidence of focal lesions.
No evidence of significant retroperitoneal, abdominal or pelvic lymphadenopathy or fluid collection.
