The radiologic "Target sign" of septic pulmonary embolism in a case of acute myelogenous leukemia.
The authors report the appearance of septic pulmonary embolism in a case of acute myelogenous leukemia. The pulmonary lesions are characterized radiographically by the uncommon appearance of central densities suspended within thin-walled pseudocystic air spaces. A possible pathogenic mechanism explaining these radiographic findings is discussed. Such images must be distinguished from those of a fungus ball or tuberculous cavities.
