Abstract

Miliary tuberculosis is the most serious form of tuberculous disease, but is rarely complicated with acute respiratory distress syndrome (ARDS). When a patient with miliary tuberculosis initially presents with ARDS, the mortality is much higher. Therefore, the early detection of miliary tuberculosis as the underlying cause of ARDS is very important for the prognosis and survival of the patient. The diagnosis of miliary tuberculosis may be easy if the patient presents typical clinical manifestations associated with the characteristic pattern of miliary nodules on chest radiology. However, the diagnosis of miliary tuberculosis when complicated with ARDS can be difficult due to the nonspecific radiologic patterns, such as diffuse bilateral consolidation and ground glass opacity, without miliary nodular infiltration. However, these nonspecific patterns are known as less likely findings of miliary tuberculosis. We experienced a pregnant woman with miliary tuberculosis, mimicking ARDS due to bilateral severe pneumonia. She was admitted, via the emergency room, with sudden onset of fever, chill, cough and dyspnea. The initial chest PA and HRCT showed diffuse bilateral consolidation and ground glass opacity, without miliary nodular infiltration. All bacteriological studies, including blood and sputum cultures, tuberculosis-PCR and serologic study for infectious disease were negative. However, the definite diagnosis of unusual miliary tuberculosis as the underlying cause of ARDS was confirmed from the radiological finding and transbronchial fiberoptic lung biopsy. We report this case, with a review of the literature.
