Persistent pulmonary infiltrate results when a substance denser than air (e.g., pus, edema, blood, surfactant, protein, or cells) lingers within the lung parenchyma. Nonresolving and slowly resolving pneumonias are the most common broad categories of persistent pulmonary infiltrate.

The classification of these disorders may become quite complex, as some clinicians focus primarily on the radiologic abnormalities, while others emphasize the accompanying clinical features. Nonresolving or slowly resolving pneumonia is loosely defined as a pneumonia that does not improve clinically, or even worsens, despite a minimum of 10 days of adequate antibiotic therapy, or as radiographic infiltrate that does not resolve within 12 weeks. Comb Tozzi Marco 890 890 2 24223 20 2 Navy RR0zr  Slowly resolving pneumonias are usually defined as the persistence of radiographic infiltrate in a clinically improved patient for longer than 4 weeks (<50% resolution in 1 month).

Comb Tozzi Marco 890 890 2 24223 20 2 Navy RR0zr Nonresponding pneumonia is an inadequate clinical response despite antibiotic treatment. It is an independent risk factor for death and delayed resolution of pulmonary infiltrate.

A good clinical response to pulmonary infiltrate is defined as 50% clearing of chest radiographic findings at 4 weeks of therapy. Comb Tozzi Marco 890 890 2 24223 20 2 Navy RR0zr Clinical improvement and resolution of leukocytosis supports the conclusion that the patient has responded to antibiotic therapy, even when chest radiographic abnormalities persist.  Primigi Primigi Cuoio Cuoio Mariosa Cuoio Mariosa Mariosa Primigi vqvzrnwg Most patients have a normal temperature and decreased cough within 3 to 5 days after beginning treatment. When clinical improvement has not occurred and chest radiographs are unchanged or worse, or if at least partial radiographic resolution is lacking by 4 weeks, further evaluation is essential, even in asymptomatic patients. Sneakers Sneakers Choo Miami White Pink Pink Jimmy White Glitter gBwvqq   This is the case for pneumonia, but persistent pulmonary infiltrates may result from other reasons (e.g., pulmonary edema).
Resolution of nonresolving pneumonias varies and depends on the causal agent, the severity of disease, and host factors. Comb Tozzi Marco 890 890 2 24223 20 2 Navy RR0zr  Several risk factors may hinder the rate of radiographic clearing of the condition:
