A case of fatal viscerotropic Rocky Mountain spotted fever with virtual absence of cutaneous lesions was diagnosed at autopsy by specific immunofluorescent demonstration of Rickettsia rickettsii in spleen, kidney, epididymis and skin. The clinical presentation was that of insidious onset of fever, renal failure, hypotension, hyponatremia and obtundation over a 10 day period. The patient had respiratory insufficiency, hypocalcemia, increases in creatinine phosphokinase (CPK), serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alkaline phosphatase, billirubin and serum phosphate, grand mal seizure, myalgia and unremitting shock with death occurring on day 12 of illness. Postmortem examination revealed severe vasculitis with interstitial nephritis and multifocal tubular necrosis, pericholangitis with bile stasis, glial nodules in the brain, multifocal rhabdomyonecrosis, interstitial pneumonitis and mild interstitial myocarditis. Risk factors which this patient shared with other patients with fatal Rocky Mountain spotted fever were failure to recognize a rash, failure to obtain a tick bite history, male sex, black race and age greater than 30 years.

Acute viral myocarditis is an uncommon but potentially fatal illness in children. Patients with myocarditis may present with nonspecific symptoms or atypical findings that make diagnosis in the emergency department difficult. We describe a previously healthy 14-month-old child with difficulty breathing and a tonic-clonic seizure who was subsequently found to have ECG changes and cardiac marker elevation consistent with acute myocardial infarction. The patient was immediately transferred from our community hospital ED to our tertiary care children's hospital. Shortly after admission, the patient developed intractable nonperfusing ventricular arrhythmias necessitating extracorporeal membrane oxygenation. Cardiac function did not recover, and the patient required heart transplantation before cessation of bypass. Serology and anatomic pathology confirmed coxsackievirus B myocarditis. This case illustrates (1) the nonspecific presentation of myocarditis as dyspnea and seizure, (2) the manner in which myocarditis can mimic myocardial infarction, and (3) the importance of early diagnosis in the ED and transfer to a tertiary care facility.
