2-year-old girl was diagnosed with pleuropulmonary blastoma (PPB). She presented with cough and fever which was treated as pneumonia. When her symptoms did not improve, a chest X-ray showed a right lower lobe infiltrate with pleural effusion and a cystic lesion superiorly. She was further treated with antibiotics and improved clinically, but follow-up with chest CT showed a persistent cystic area in the right lower lobe and pneumothorax. She thus underwent pleural drainage and thoracoscopic biopsy, revealing a diagnosis of "cystic pleuropulmonary blastoma".

65-year-old female that suffers from pain in the left knee underwent examinations that showed femoral-tibial arthrotic manifestations, external degenerative meniscal tear and moderate joint effusion. A diagnosis of external degenerative meniscal tear was established. Further medical tests showed marked degeneration of the meniscal fibrocartilage, diffuse femoral-tibial arthrotic abnormalities, subchondral cysts and edema of the spongious bone, as well as rarefaction of the cartilage matrix, and manifestations of chondropathy.

39-year-old male experienced in 1994 intense lower back pain after lifting weights, with spontaneous resolution. In 2006, he again experienced lower back pain radiating into both thighs. A lumbar MRI showed degenerative changes and EMG test showed L5 nerve root irritation. His physical examination demonstrated increased reflexes and a concern for cervical stenosis was entertained. Further cervical MRI and lumbar studies showed arthritic changes, and the thoracic MRI showed evidence of spinal cord compression. The surgeon suggested posterior thoracic laminectomy.
