ABSTRACT
An 88-year-old woman complained of right quadrant abdominal pain and severe edema in both legs. She had a history of pulmonary embolism one month ago. Abdomen CT showed a huge hepatic cyst compressing the intrahepatic portion of the inferior vena cava (IVC). The venogram CT showed multifocal thrombosis in the iliocaval and both lower extremity veins. Percutaneous hepatic cyst drainage was carried out. Fluid analysis presented leukocytosis, which suggested an infected hepatic cyst. To prevent secondary pulmonary thromboembolism, an IVC filter was inserted before catheter drainage for the hepatic cyst. One week later, abdominal pain was relieved. Then, sclerotherapy for the remnant hepatic cyst was performed by ethanol. Follow-up CT showed an increased amount of thrombosis in the iliocaval and left calf vein, but the IVC filter prevented another thromboembolic event successfully. The patient started dabigatran, a new oral anticoagulant, and compression stockings were applied to both legs. After one month, no visible thrombosis in the pelvis or either extremity was detected in abdominal CT. This case suggests that a huge hepatic cyst, especially with infection, should be considered as a possible cause of deep vein thrombosis if no other risk factors for thromboembolism exist.

A 47-year-old male with recurrent abnormal behavior for ten years was referred to our clinic. He was diagnosed with insulinoma and cognitive dysfunction. Persistent hypoglycemia leads to a high risk of cognitive dysfunction in diabetic patients. However, cognitive dysfunction associated with insulinoma is rare. In this case study, cognitive dysfunction was confirmed by neurological testing.

In patients with primary aldosteronism who have bilateral adrenal incidentalomas, it is important to identify which adrenal gland is secreting excess aldosterone. Traditionally, adrenal vein sampling (AVS) has been performed for lateralization despite its invasiveness. Here we report a case of bilateral adrenal incidentaloma in which 18-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) was used to identify the functional adrenal mass. A 53-yr-old man was referred to our clinic due to bilateral adrenal incidentalomas (right: 1 cm, left: 2.5 cm) on computed tomography (CT). Given his history of colon cancer, FDG-PET/CT scanning was used to rule out metastasis. Although there was focal hot uptake lesion in the right adrenal gland, the patient was suspected primary aldosteronism clinically more than metastasis because of the patient's underlying hypertension with hypokalemia. It was consistent with the results of AVS. Based on these findings, we propose that FDG-PET/CT can be used instead of AVS to identify the source of primary aldosteronism between two bilateral adrenal incidentalomas.

BACKGROUND/AIMS: The prevalence of occult HBV infection (OBI) in patients with chronic hepatitis C (CHC) in Korea has not been reported. Additionally, it is unclear whether OBI influences treatment outcome in CHC patients. We investigated the prevalence of OBI and its impact on treatment outcome in patients with CHC. METHODS: Seventy-six patients with CHC were enrolled and treated with pegylated or conventional interferon and ribavirin. Hepatitis B virus (HBV) DNA was detected by nested polymerase chain reaction. RESULTS: Among the 68 patients who completed treatment and follow-up, HBV DNA was detected in serum from nine (13.2%) patients, liver tissue from 10 (14.7%), and serum or liver tissue from 15 (22.1%). OBI was diagnosed in nine (12.7%) control subjects. No difference in the prevalence of OBI between patients with CHC and controls was observed (13.2 vs. 12.0%; p = 0.92). No significant differences in age, sex, genotype 1 frequency, amount of hepatitis C virus RNA, anti-hepatitis B surface antigen/anti-hepatitis B core-IgG seropositivity, staging, or histology grading were observed in patients with or without HBV DNA. Sustained virological response was achieved in 73.3% of patients with OBI and 83.0% without OBI (p = 0.46). CONCLUSIONS: These results demonstrate that a significant proportion of patients with CHC have occult HBV infection and that OBI does not affect treatment outcome in patients with CHC.
