Pylephlebitis (septic thrombophlebitis of the portal venous system) is a rare but serious complication of intra-abdominal infections that drain into the portal venous system. Its diagnosis is based on imaging; computed tomography may reveal a thrombus in the portal vein. Bacteremia may also be evident. As the symptoms are nonspecific, early clinical diagnosis is difficult, and delayed treatment can compromise outcomes. We report a case with extensive pylephlebitis and a liver abscess associated with Streptococcus intermedius sepsis; the case was treated successfully with antibiotics and anticoagulants. Such cases have not been widely reported.

A nasal septal abscess results from the collection of purulent fluid between the cartilage of bony septum and overlying mucoperichondrium or mucoperiosteum. Unless early diagnosis and surgical treatment are performed, serious complications such as cavernous sinus thrombophlebitis, sepsis, and saddle nose may occur. We report a case of septal abscess and sphenoid sinusitis that occurred after dental implant. A 74-year-old female with diabetes and liver cirrhosis was referred to the hospital for management of rapidly aggravated perinasal pain, nasal obstruction, and headache. The patient had undergone dental implant in the right upper incisor area 6 days ago. A CT revealed septal abscess and bilateral sphenoid sinusitis. The patient was operated upon to drain septal abscess, and both sphenoid sinuses were opened widely.

BACKGROUND/AIMS: Recurrent pyogenic cholangitis (RPC) is a chronic progressive disease frequently accompanied by cholangiocarcinoma (CCA). This study aimed to investigate the natural course of RPC and identify factors associated with CCA. METHODS: From January 2005 to December 2016, 310 patients diagnosed with RPC at Seoul National University Hospital were included. Complications and management during follow-up were recorded. CCA-free probability was estimated by Kaplan-Meier method, and risk factors associated with CCA were analyzed using log-rank test and Cox’s proportional hazard regression model. RESULTS: Mean age at diagnosis was 59.1±10.9 years and mean follow-up duration was 84.0±64.1 months. An intrahepatic duct stone was found in 253 patients (81.6%). Liver atrophy was identified in 185 patients (59.7%) and most commonly located at the left lobe (65.4%). Acute cholangitis, liver abscesses, cirrhotic complications, and CCA developed in 41.3%, 19.4%, 9.7%, and 7.4%, respectively. During follow-up, complete resolution rate after hepatectomy, biliary bypass surgery, and choledocholithotomy with T-tube insertion reached 82.3%, 55.2%, and 42.1%, respectively. None of the patients who maintained complete resolution by the last follow-up day developed CCA. In univariate analysis, female, both-sided intrahepatic duct stones, and liver atrophy at any location were associated with increased risk of CCA. Multivariate analysis revealed that both-sided atrophy significantly increased risk of CCA (hazard ratio, 4.56; 95% confidence interval, 1.48 to 14.09; p=0.008). In 21 patients who developed intrahepatic CCA, tumor was located mostly in the atrophied lobe (p=0.023). CONCLUSIONS: In RPC patients, acute cholangitis, liver abscess, cirrhotic complications, and CCA frequently developed. Both-sided liver atrophy was a significant risk factor for developing CCA.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease affecting various organs. Among its manifestations, inflammatory pseudotumor (IPT) is an extremely rare disease about which no case has been reported of it occurring in the liver. We present a case of a SLE patient with hepatic IPT (hIPT) successfully treated with immunosuppressants. A 16-year-old male with elevated liver enzymes visited our clinic and was diagnosed as SLE. Although no lesion was observed in the initial abdomen ultrasonography, the abdominal CT on hospital day 7 revealed a new hepatic mass resembling an abscess. Despite 5 weeks of antibiotics treatment, the hepatic mass remained, and was re-diagnosed as hIPT secondary to SLE with an abdominal MRI. After high dose prednisolone and mycophenolate mofetil treatment, lupus activity subsided and hIPT disappeared in the follow-up CT. This case suggests that hIPT should be considered as a differential diagnosis among hepatic mass in SLE patients.

Emphysematous osteomyelitis, characterized by intraosseous gas, is a rare but potentially fatal condition that requires prompt diagnosis and aggressive therapy. Causative organisms are members of the bacterial family Enterobacteriaceae or anaerobes in most cases and significant comorbidities such as diabetes mellitus and malignancy, may predispose an individual to the development of emphysematous osteomyelitis. We report a case of extensive emphysematous osteomyelitis via hematogenous spread from Klebsiella pneumoniae liver abscess, complicated by gas-containing abscesses in adjacent soft tissues and epidural space, and multiple systemic septic emboli in a diabetic patient.

Since the mid 1980s, the prevalence of liver abscess caused by hypervirulent Klebsiella pneumoniae strain has increased in Asia, particularly in Taiwan and Korea. This strain is mostly K1 or K2 serotype, and has hypercapsular and hypermucoid phenotypes. Most infections are community acquired, and patients rarely have a hepatobiliary disease prior to infection. Clinical manifestations are characterized by fever and high C-reactive protein, and metastatic infections, such as septic emboli in the lung and endophthalmitis and meningitis are frequently observed. Antibiotic resistance is rare. Antibiotic treatment and abscess drainage are needed, and early diagnosis and treatment of endophthalmitis is also important.

During chemotherapy in patients with gastrointestinal malignancy, the hepatic lesions may occur as chemotherapy-induced lesions or tumor-associated lesions, with exceptions for infectious conditions and other incidentalomas. Focal hepatic lesions arising from chemotherapy-induced hepatopathies (such as chemotherapy-induced sinusoidal injury and steatosis) and tumor-associated eosinophilic abscess should be considered a mimicker of metastasis in patients with gastrointestinal malignancy. Accumulating evidence suggests that chemotherapy for gastrointestinal malignancy in the liver has roles in both the therapeutic effects for hepatic metastasis and injury to the non-tumor bearing hepatic parenchyma. In this article, we reviewed the updated concept of chemotherapy-induced hepatopathies and tumor-associated eosinophilic abscess in the liver, focusing on the pathological and radiological findings. Awareness of the causative chemo-agent, pathophysiology, and characteristic imaging findings of these mimickers is critical for accurate diagnosis and avoidance of unnecessary exposure of the patient to invasive tissue-based diagnosis and operations.

Heterogeneous features of liver cancer can mimic liver abscess. Therefore it is essential to double-check tumor markers in the diagnosis of liver abscess. Herein, we report a case of combined hepatocellular-cholangiocarcinoma (cHC) occurred in an unrecognized chronic hepatitis B patient initially misdiagnosed as liver abscess. A 49-year old male initially presented with chill, right upper quadrant pain, and a liver mass. Mass showed peripheral enhancement in arterial phase of computed tomography, which was not typical for hepatocellular carcinoma (HCC). Strikingly elevated alpha-fetoprotein and fine needle aspirated pathology revealed HCC. Despite discordant image findings he was treated with transarterial chemoembolization. He was treated with sorafenib due to metastatic retrocaval lymphadenopathy afterwards. The mass presumed to be HCC progressed with sorafenib. It was surgically resected and he was finally confirmed as cHC. Discordant tumor markers with presumptive image findings should prompt the suspicion of rare type of primary liver cancer, the cHC.
