Cryptogenic Pyogenic Liver Abscess in a Small Infant

Abstract

Before an operation, it was suggested by diagnosis that the liver neoplasm was probably malignant. Following division of the resected specimen, cryptonic pyogenic liver abscess was diagnosed. This is a rare case for small infants. It is common to perform liver excision for single or localized pyogenic liver abscesses, however, there are cases where malignancy cannot be denied completely. Since a malignant tumor was suspected in this case, we judged that liver biopsy before operation was extremely dangerous, and right lobectomy was performed via abdominal incision. The pathological diagnosis of the resected specimen presented findings compatible with pseudo tumor. It is believed that liver excision was a suitable medical treatment for pyogenic liver abscess in this case.
