As in the nonpregnant population, lung ultrasonography would be most attractive if it has good positive and negative predictive value, is safe, and there is expertise with using and interpreting it locally. It is common for providers to withhold tests in a pregnant patient due to presumed risks to the fetus. This may lead to delays in diagnosis as well as diagnostic and therapeutic errors, resulting in similar or worse harm. In this case report, chest radiograph was initially withheld, and pulmonary embolism (PE) was excluded based on Doppler testing of the legs alone. Though PE was unlikely in this patient, clinicians had a high enough suspicion to empirically initiate anticoagulation treatment, bypassing diagnostic testing. Such practices are considered substandard care in the nonpregnant population; the same should apply to pregnancy.
