A 70-year-old woman with poorly controlled diabetes mellitus was admit
ted because of persistent remittent fever. Soon a liver abscess was de
tected as the cause of the fever by ultrasonography, and antibiotic th
erapy was started. However, suddenly serious dyspnea with chest and ba
ck pain developed. The morbid condition was definitely diagnosed as se
ptic pulmonary emboli (SPE) with pulmonary perfusion scan. It should b
e recognized that liver abscess can be a latent focus of systemic meta
static complications such as SPE, and not only early detection but als
o prompt appropriate drainage of liver abscesses is essential.
