Suggested Answer: D Vote an answer

The presence of the "spine sign" on chest x-ray is indicative of bilateral lower lobe pneumonia.
When something abnormal interposes itself and superimposes on the lower thoracic spine, the spine may "appear" to become whiter rather than darker just above the diaphragm. This effect is called the
"spine sign." The spinal markings disappear at the level of bilateral lower lobe pulmonary infiltrates, which occlude visibility of the vertebrae.
