Liver Abscess due to Gemella morbillorum in a Healthy Woman

  • 1Department of Internal Medicine, Wallace Memorial Baptist Hospital, Busan, Korea.


Gemella morbillorum is a normal flora of the oral cavity, upper respiratory tract, gastrointestinal tract, or genitourinary system. Human infection cause by G. morbillorum is very rare. Known predisposing conditions are intravenous drug abuse, alcoholism, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, renal disease and poor oral hygiene. Most reported cases are infective endocarditis and vasculitis. We experienced a case of liver abscess by G. morbillorum in a healthy young woman, who was treated successfully with antibiotics and drainage. We report this case along with a literature review.

  • Figure 1 Initial abdominal CT images showing a 12×7.5×13 cm, multi-septated, enhancing, thick walled cystic mass in the right posterior segment of the liver. (A) pre-enhanced phase, (B) arterial phase, (C) portal phase, (D) delayed phase.

  • Figure 2 On hospital day 30, a follow up CT scan revealed a nearly resolved liver abscess with drain catheter insertion state.
