Intraosseous gas may be seen in a number of conditions. The cause can often be determined from history and imaging studies.
Differential diagnosis of intraosseous gas:
(1) intraosseous pneumatocyst
(2) osteomyelitis with gas-forming bacteria
(3) lymphangiomatosis of bone (following biopsy or surgery)
(4) scuba diving or exposure to other pressure environments
(5) vertebral collapse following osteonecrosis
(6) trauma or surgery
