Objective: To compare ultrasound (US) and computed tomography (CT) for evaluating
patients with complicated pneumonia admitted to the intensive care unit (ICU) to assess if US can
be an alternative to CT.
Subjects and methods: We prospectively compared US and CT findings in 48 patients admitted to
the ICU with complicated pneumonia with their final diagnosis at discharge. Images were evaluated
for parenchymal findings (consolidation, necrosis, and abscess) and pleural findings (effusion, loculation
or fibrin strands in the pleural fluid).
Results: US was similar to CT in the evaluation of parenchymal and pleural abnormalities except
for two patients with consolidation and effusion, three patients with loculated effusion, one patient
with pulmonary necrosis and another patient with lung abscess. US was superior to CT in detection
of fibrin strands within pleural effusion.
Conclusion: Chest US provides an accurate evaluation of the pleural and parenchymal abnormalities
associated with complicated pneumonia in the ICU patients. Considering that chest US is a
bedside and avoids transportation of the patient outside ICU, free of radiation exposure and easily
repeatable, chest US appears to be an attractive alternative to CT.
