IgG4-related Sclerosing Cholangitis Presented as a Mass in the Liver / 대한췌담도학회지

Autoimmune pancreatitis or IgG4-related sclerosing cholangitis often involves the liver. Most common lesion involving the liver is shown as mass or masses often referred as inflammatory pseudotumor. Inflammatory pseudotumor usually needs to be discriminated with malignancy. Here we report a case of IgG4-related sclerosing cholangitis with liver involvement presented as a mass. It was proven by biopsy and did not show any evidence of autoimmune pancreatitis. The mass infiltrated around the portal tract and portal vein thrombosis was also present.

Long-term Successful Treatment of Massive Distal Duodenal Variceal Bleeding with Balloon-occluded Retrograde Transvenous Obliteration / 대한소화기학회지

Duodenal variceal bleeding in patients with portal hypertension due to cirrhosis or other causes is uncommon. We report on a case of a 55-year-old male with an ectopic variceal rupture at the distal fourth part of the duodenum who presented with massive hematochezia and shock. Shortly after achievement of hemodynamic stability, due to the limitation of an endoscopic procedure, we initially attempted to find the bleeding focus by abdominal computed tomography, which showed tortuous duodenal varices that drained into the left gonadal vein. He was treated with first-line balloon-occluded retrograde transvenous obliteration (BRTO), resulting in a favorable long-term outcome without rebleeding three years later. This case suggests that BRTO may be a first-line therapeutic option for control of ruptured duodenal varices, especially at a distal location.

Diffuse Skeletal Hemangiomatosis Mimicking Sacroiliitis

Hemangiomatosis of the skeletal system is a rare disease without specific symptoms and signs. We describe a 20-year-old patient with low back pain, whose plain radiographs of sacroiliac (SI) joint showed irregular sclerotic lesions. The patient was finally confirmed with skeletal hemangiomatosis by magnetic resonance imaging (MRI) and excisional biopsy of the lesion. The present case suggests that if patients with abnormal lesions of the SI joint in the plain radiographs do not have typical inflammatory back pain, advanced imaging is required to make an accurate diagnosis. Our case also emphasizes the importance of MRI and biopsy in establishing the diagnosis.

Splenic Hemorrhage with Hemoperitoneum Caused by a Snakebite / 대한구급학회지

In Asia, snakebites are estimated to affect 4 million people every year, and of these, 100,000 people are estimated to die. In Korea, snakebites occur frequently from the spring to the fall, but their importance is often overlooked. Fatal complications, including acute respiratory distress and acute kidney injury, can occur, and in some cases, severe hemorrhage results from coagulopathy. There have been only a few cases of snakebite-induced liver or intestinal bleeding, but to our knowledge, spontaneous bleeding from the spleen has not been previously reported. Here, we report the case of a 61-year-old male who visited the emergency room with abrupt abdominal pain due to hemoperitoneum associated with splenic hemorrhage after a snakebite.

Disseminated Cryptococcosis with Cutaneous Manifestation in a Renal Transplant Recipient: A Case Report / 대한이식학회지

Cryptococcosis commonly affects patients with immune dysfunction, as in the case of immunosuppression in organ transplant patients or as acquired immunodeficiency syndrome in patients afflicted with human immunodeficiency virus. The varied appearance of cryptococcal skin lesion makes clinical diagnosis of cutaneous cryptococcosis difficult. Cryptococcosis proves to be a fatal fungal infection in the immunocompromised patient. Therefore, diagnosis and early treatment of cryptococcosis become vital. A 56-year-old renal transplant recipient, with an ongoing immunosuppression regimen of cyclosporine, prednisolone, and mycophenolate mofetil, was admitted with a 2-week history of pain and edema of right arm without respiratory symptoms. Despite empiric antibiotic therapy, the patient continued to complain of severe tenderness of the involved arm and fever persisted as well. On the third day of hospital stay, a biopsy of the erythematous skin lesion was acquired. On the eighth day of hospital stay, results of both skin biopsy and blood cultures showed the presence of Cryptococcus neoformans. The treatment was begun with intravenous fluconazole (400 mg/day). After 4 days of antifungal treatment, the patient developed fever along with cough with purulent sputum. As the new developing symptoms were suggestive of pneumonia, especially of pulmonary cryptococcosis, the antifungal agent was changed from fluconazole to amphotericin B treatment (0.8 mg/kg, 50 mg/day). Chest computer tomography showed improvement in the pneumonic infiltration and consolidation after 4 weeks of amphotericin B treatment. In conclusion, cellulitis in immunocompromised patients should be suspected in case of highly atypical infectious etiology, and skin biopsy should not be delayed if empiric antibiotic therapy does not control the inflammatory response. Additionally, the patient should be treated with intravenous amphotericin B treatment in case of severe cryptococcosis.
