Splenosis Mimicking Cancer
A 62-year-old woman with progressive shortness of breath and a 40-pack-year smoking history was referred for pulmonary evaluation after a radiograph of the chest showed nodularity along the left hemidiaphragm (Panel A, arrows), raising the possibility of cancer. The radiograph was otherwise unremarkable except for hyperinflation suggestive of emphysema and mild thoracic scoliosis. Her medical history was notable for a gunshot wound to the thoracoabdominal region 28 years earlier, which had resulted in injury to the liver, left hemidiaphragm, and spleen, requiring a laparotomy and splenectomy..
