    Abstract:
    A 55-year-old woman who developed severe hypoxemia associated with severe pneumonia was admitted to our hospital for mechanical ventilation. She was treated with antibiotics under a diagnosis of mycoplasma pneumonia. Although most clinical findings improved, hypoxemia remained. As a chest CT film showed multiple nodules and an enhanced CT film revealed arterial filling in the nodules, multiple pulmonary arteriovenous fistulas (PAVFs) were considered to be an underlying cause of hypoxemia. Transcatheter coil embolization for 5 PAVFs, significantly ameliorated hypoxemia in the patient. PAVF is a congenital desease, and in many cases, is asymptomatic. Therefore, it was rare for PAVFs to be detected in a middle-aged patient with prolonged hypoxemia associated with pneumonia.
