 Introduction

A44-year-old
woman was admitted to our institution with a history
of shortness of
breath on mild exertion, cough, fever, and weight
loss of 20 pounds.
Past history was not significant until 2
months before the
hospitalization, when she developed weakness
and cough with occasional
mucoid sputum. She did not smoke or
take any medication. Examination
revealed no lymphadenopathy,
jaundice, or neck vein engorgement but did
show mild hepatomegaly.
A chest radiograph and CT of the thorax showed
multiple nodules
2 to 3 cm in diameter in both lung fields suggestive
of multiple
pulmonary emboli. A lung ventilation/perfusion scan
was positive
for multiple pulmonary emboli. Leg ultrasound was
negative for
deep venous thrombosis. An ECG showed sinus
tachycardia. Laboratory
tests demonstrated marked
eosinophilia, with negative
Brucella,
Q fever, rheumatoid
factor, anti-nuclear antibody, anti–hepatitis
C virus, and
hepatitis B surface antigen tests.
