A Case of Pyogenic Liver Abscess with Multiple Septic Metastatic Infections and Colon Cancer

Klebsiella pneumoniae (K. pneumoniae) is one of the most common pathogens to cause liver abscess. Because K. pneumoniae is highly virulent, it may cause embolic complications. The rate of metastatic infection has a range of 3.5% to 20%. Thus, a diagnostic work-up for metastatic complications should be employed in K. pneumoniae liver abscess cases, including chest radiography and computed tomo graphy if chest radiographies are abnormal and ophthalmic examination in diabetic patients. Cryptogenic pyogenic liver abscess has been recently reported to potentially signal colorectal cancer, especially in female patients with diabetes. We present a case of liver abscess with endophthalmitis and septic pulmonary embolism, which is associated with silent colon cancer.
