Primary hepatic actinomycosis is one of the chronic abscess-forming infections of the liver. Accurate diagnosis is frequently delayed due to its indolent course and nonspecific clinical and radiological manifestations. We report a case of a 57-year-old man presenting with asymptomatic multiple hepatic masses on follow-up abdominal computed tomography performed 1 year after stomach cancer surgery. Although a percutaneous liver biopsy procedure was conducted twice in order to obtain confirmative pathology, only a nonspecific organizing abscess with plasma cell infiltration was revealed, without identification of any organism in the tissue cultures. Ultimately, actinomycosis was diagnosed following the detection of sulfur granules on open surgical biopsied tissue. This case suggests that primary hepatic actinomycosis should be considered as one of the possible causes for enigmatic inflammatory lesions of the liver.

BACKGROUND/AIMS: Despite the improvement of personal and social hygiene, pyogenic liver abscess is still a common disease. We compared the incidence, infection route, underlying disease and major complications between two different local hospitals. METHODS: We reviewed the clinical data of 100 patients with pyogenic liver abscess who were treated at Seoul and Guri Hanyang University Hospital from 1999 to 2003. RESULTS: There were 64 males and 36 females in the study group; they were aged from 19 to 94 years with a mean of 56.5 years. Every year 19 to 23 pyogenic liver abscess patients were admitted to both hospitals. The most common organism isolated was Klebsiella pneumoniae in both local hospitals. In the Seoul hospital, diabetes (40.9%) was most common associated condition. In the Guri hospital, biliary tract disease or a history of hepatobiliary surgery (54.2%) was the most common associated condition. Catheter drainage and/or percutaneous needle aspiration were established as the standard treatment modality. CONCLUSIONS: In both regional hospitals, the incidence of pyogenic liver abscess did not decrease and Klebsiella pneumoniae was the most common organism. Diabetes and biliary tract disease, including, previous hepatobiliary surgery, were the most identifiable underlying disease.

Glomerulonephritis associated with visceral abscess is being increasingly recognized. The association of glomerulonephritis with visceral suppuration in the absence of endocarditis was first described by Whitworth and associates. Abscesses were most frequently located in the respiratory tract but have been reported at numerous other sites, including appendix, uterus, aorto-femoral bypass graft and cutaneous wound. This report documents the apparently rare occurrence of glomerulonephritis with acute renal failure in association with pyogenic liver abscess. The need for awareness of glomerulonephritis as a cause of acute renal failure in pyogenic liver abscess is highlighted.

BACKGROUND/AIMS: Hepatic or splenic lesions in hematologic patients are not defined well because they are not easy to evaluate due to limitations of invasive procedures. Management typically depends on the clinical diagnosis with few microbiological data. METHODS: We reviewed the medical records of consecutive hematologic patients with hepatic or splenic lesions in the infectious diseases unit from April 2009 to December 2010 at the Catholic Hematopoietic Stem Cell Transplantation Center in Korea. RESULTS: Twenty-six patients were identified. Their mean age was 46.0 +/- 14.7 years, and 16 (61.5%) were male. Underlying diseases were acute myelogenous leukemia (n = 15, 57.7%) and myelodysplastic syndrome (n = 6, 23.1%). Among the nine nontuberculous infectious lesions, two bacterial, six fungal, and one combined infection were identified. The numbers of confirmed, probable, and possible tuberculosis (TB) cases were one, three, and four, respectively. Two patients had concurrent pulmonary TB. QuantiFERON-TB Gold In-Tube (QFT-GIT, Cellestis Ltd.) was positive in seven cases, among which six were diagnosed with TB. The sensitivity and specificity of QFT-GIT were 75% and 81.3%. Nine (34.6%) were defined as noninfectious causes. CONCLUSIONS: Causes of hepatic or splenic lesion in hematologic patients were diverse including TB, non-TB organisms, and noninfectious origins. TB should be considered for patients not responding to antibacterial or antifungal drugs, even in the absence of direct microbiological evidence. QFT-GIT may be useful for a differential diagnosis of hepatosplenic lesions in hematologic patients.

Necrotizing pancreatitis is one of the rare complications of transcatheter arterial chemoembolization (TACE). Necrotizing pancreatitis after TACE may result from the development of ischemia caused by regurgitation of embolic materials into the vessels supplying the pancreas. We report a case of post-TACE necrotizing pancreatitis with abscess formation in a patient with hepatocellular carcinoma. The patient had suffered hepatic artery injury due to repetitive TACE; during his 25th TACE procedure he had submitted to selective catheterization of the feeding vessel from the dorsal pancreatic artery with a cytotoxic agent and Gelfoam particles. The patient complained of abdominal pain after the TACE procedure, and a CT scan led to a diagnosis of necrotizing pancreatitis with abscess formation. The pancreatic abscess progressed despite general management of the pancreatitis, including antibiotics. Percutaneous catheter drainage was performed, and the symptoms of the patient improved.

Klebsiella pneumoniae liver abscess has a tendency to spread to distant sites early in the course of disease and to involve multiple organs synchronously. A 59-year-old male was admitted because of liver abscess accompanied by fever and abdominal pain. The patient underwent percutaneous catheter drainage and received intravenous antibiotics. Symptom relief was achieved after the treatment as well as marked reduction in the size of the abscess. Despite proper treatment of the liver abscess, however, patient developed multiple metastatic infections in a non-concurrent manner: left and right endophthalmitis, psoas abscess, and infectious spondylitis at 5, 23, 30 and 65 days after initial manifestations of liver abscess, respectively. Each infectious episode followed one another after resolution of the former one. For each episode of metastatic infections, the patient promptly underwent treatment with systemic and local antibiotics, interventional abscess drainage, and surgical treatments as needed. The patient fully recovered without sequelae after the use of intravenous antibiotics for an extended period of time. Herein, we report a case of K. pneumoniae liver abscess complicated with delayed-onset multiple metastatic infections.

Fusobacteria are anaerobic gram-negative, non-spore forming bacilli found in normal flora of the oral cavity, urogenital tract, and gastrointestinal tract. Fusobacterium nucleatum has been seldom reported as a cause of liver abscess, particularly in immunocompetent hosts. A 55-year-old man with frequent periodontal disease visited our hospital with intermittent fever and headache for 2 months. Abdominal CT scan revealed an 8.2x6 cm mass in the right hepatic lobe with central low density. Abscess culture revealed F. nucleatum as the causative organism. Percutaneous abscess drainage and intravenous administration of antibiotics for 4 weeks improved symptoms and decreased the abscess size. We report a rare case of liver abscess due to F. nucleatum in an immunocompetent man with periodontal disease.

Neutropenic enterocolitis is a serious complication of chemotherapy for malignancies such as acute leukemia or lymphoma. The acute inflammatory disease may involve the terminal ileum, cecum and ascending colon. Although conservative care is recommended as the primary treatment modality, surgical intervention is essential for intestinal perforations, abscesses, or bleeding. We experienced a case of neutropenic enterocolitis with a liver abscess in a young leukemia patient. A 13-year-old boy with acute myelogenous leukemia had completed two cycles of chemotherapy (Arabinoside 300 mg, Dactinomycin 40 mg, VP-16 150 mg, 6- mercaptopurin 60 mg, dexametasone 3 mg). Ten days after completing the second cycle he had abdominal pain, low abdominal tenderness and a high fever. The WBC count in the peripheral blood was 210 cell/mm3. A CT scan demonstrated wall thickening of the terminal ileum and ascending colon, as well as 5 cm, and 6 cm sized homogeneous low-density areas in both hepatic lobes. A presumptive diagnosis was neutropenic enterocolitis with a liver abscess. The patient was managed conservatively with fluid resuscitation, a bowel rest, and broad-spectrum antibiotics. Twenty-five days later his abdominal pain was abruptly aggravated. The CT scan and Chest X-ray demonstrated free air in the peritoneal cavity. An emergency laparotomy was performed under a diagnosis of peritonitis with an intestinal perforation. The laparotomy show that, there were perforations at the pylorus of the stomach, and full thickness necrosis at multiple segments of the small bowel. Primary closure of the stomach, a segmental resection and an end-to-end anastomosis of the small bowel, and ileostomy were performed. However, postoperative leakage developed at the stomach. The patient recovered with supportive management. The patient had a third chemotherapy series 3 months after surgery. Three days after completing the third cycle, the patient developed peritonitis. A pyloric re-perforation of the stomach was observed on the laparotomy. Postoperative leakage developed after the primary closure of the stomach. The patient died of sepsis 54 days later. Therefore, intensive monitoring and close collaboration between the hematologist and the surgeon is essential for patients with neutropenic enterocolitis. Postoperative complications are quite common and can be fatal in patients with neutropenic enterocolitis that develops after chemotherapy.

Lactococcus lactis cremoris infections are very rare in humans. We experienced liver abscess and empyema due to L. lactis cremoris in an immunocompetent adult. A 42-yr-old man was admitted with fever and abdominal pain. Abdominal computed tomography (CT) revealed a liver abscess and chest CT showed loculated pleural effusion consistent with empyema. L. lactis cremoris was isolated from culture of the abscess material and blood. The patient was treated with pus drainage from liver abscess, video-assisted thoracoscopic decortications for empyema, and antibiotics including cefotaxime and levofloxacin. The patient was completely recovered with the treatment. To our knowledge, this is the first report of a L. lactis cremoris infection in Korea.
