Rocky Mountain spotted fever (RMSF) is a well-described, potentially lethal, tick-borne zoonotic infection and has very effective therapy. However, the diagnosis might not be made early enough, often leading to worse outcomes. ⋯ We present this case to raise awareness of RMSF in patients who present with a nonspecific febrile illness in tick-endemic areas in the United States. Early diagnosis and treatment with doxycycline before day 5 of illness is essential and can prevent morbidity and mortality.

Among patients who die from pulmonary embolus (PE), approximately two-thirds succumb within an hour of presentation. Computed tomography can provide a definitive diagnosis but is associated with practical limitations. Echocardiography can increase diagnostic certainty of PE by visualizing signs of acute right ventricular (RV) strain. This case highlights a potentially lethal finding associated with PE and the role of clinician-performed bedside echocardiography in the timely management of this disease. ⋯ The clinician performed a focused echocardiogram to evaluate the cause of the patient's critical state. PE-in-transit, a rare entity associated with large PEs, was identified, which obviated the need for further diagnostic evaluation and led to immediate aggressive therapy. Increased familiarity with the uses of bedside sonography in the evaluation of shock and respiratory distress may allow clinicians to become more proficient in managing these patients.
