THE OFTEN described roentgenographic features of staphylococcal pneumonia1-3 include a rapidly changing x-ray picture which may proceed from that of pneumonic infiltrate to one of large air-filled cavities within the space of a few hours.4 Rupture of these pneumatoceles may produce a tension pyopneumothorax. The initial infiltrate may be focal, segmental, or lobar in distribution or may involve one or both lungs in their entirety and has almost always been described as being patchy in appearance but not as a homogenous lobar consolidation resembling neoplastic change. The following patients presented to us with x-ray findings initially thought to represent neoplastic involvement of the upper lobe area.
