Giant Hyperplasia of the Caudate Lobe in a Patient with Liver Cirrhosis: Case Report and Literature Review

The caudate lobe often exhibits enlargement and nodularity in cases of cirrhosis, which makes differentiation of hepatocellular carcinoma from other mass-like lesions of the caudate lobe difficult in cirrhotic patients. A 12x6 cm mass-like enlargement of the caudate lobe was incidentally found by computed tomography in a 38-year-old man suffering from alcoholic liver cirrhosis. Magnetic resonance imaging, liver colloidal scan, and sonoguided liver biopsy were used for the differential diagnosis. A literature review revealed two case reports, all of which (like ours) presented with an enlarged caudate lobe supplied with blood via a branch of the portal vein. Therefore, in cases of giant hyperplasia of the caudate lobe, confirmation of the caudate lobe blood supply and the enhancement pattern might be important for the differentiation.

Clinical Features of Eosinophilic Gastroenteritis / 대한소화기학회지

BACKGROUND/AIMS: Eosinophilic gastroenteritis (EG) is an uncommon disease with various gastrointestinal symptoms characterized by eosinophilic infiltration. Its incidence increases recently. We investigated the clinicopathologic features of the patients with EG. METHODS: Between January 1970 and July 2003, a total of 28 cases of EG have been reported. By adding 3 cases diagnosed in the Eulji Hospital, we evaluated the 31 cases of EG for the symptoms, laboratory findings, histologic findings, method of treatment, and allergic history. RESULTS: The incidence increased during 1990s. The predominant site of the eosinophilic infiltration was mucosa in 10 cases, muscularis in 5 cases, and subserosa in 5 cases. The remaining 11 patients had the EG in two sites. The most frequently affected organ was small intestine (12 patients), but there were 12 cases which more than two organs involved. Melena and hematochezia were dominant findings in the patients whose infiltration occurred in mucosa. On the other hand, ascites was a dominant finding in the cases that infiltration occurred in subserosa or involving over 2 layers. There was no difference in eosinophilia, clinical symptoms, and duration between two groups according to the symptom duration for less or more than 30 days. Additionally, seven patients had allergc histories. Peripheral eosinophilia was found in 24 cases. There was no recurrence of EG after the treatment. CONCLUSIONS: Our retrospective studies about EG reported in Korea could not clarify whether EG is related to allergy. Recently, the occurrence of EG is increasing and it is frequently involved in young men. The most apparent finding include peripheral eosinophilia. There is no significant clinical feature which is consistent with Klein's classification, though blood loss was more common in mucosal type and ascites was more common in serosal type and in case above two layers.
