Lymphangioma, a benign neoplasm of the lymphatic system, is common in children but rare in adults. Its clinical manifestations include abdominal pain, nausea, vomiting and a palpable mass. However, abdominal sonography or abdominal computed tomography (CT) scan can also incidentally reveal lymphangioma. A larger or symptomatic lymphangioma is treated with total resection to prevent recurrence, infection, torsion and enlargement. Although lymphangioma rarely becomes malignant, its prognosis is generally good. We report a cystic lymphangioma of the spleen and retroperitoneum, which was incidentally found in a 56-year-old man who was hospitalized due to a colon mass. Physical examination showed no specific findings. Abdominal CT revealed a 5.7 cm, non-enhanced multilobulated cystic mass with multiple septa in the spleen and a 10 cm lobulated cystic mass in the paraaortic area. Splenectomy and retroperitoneal resection of the cystic mass were conducted. The endothelium of splenic and retroperitoneal cyst was immunohistochemically stained with D2-40 antibody. The patient was finally diagnosed with splenic cystic and retroperitoneal cavernous lymphangioma.
Background/AimsGastric stasis in migraineurs remains controversial. The aim of this study is to investigate gastric emptying (GE) time, and any associations between GE parameters and dyspeptic symptoms among patients with functional dyspepsia (FD) and migraine without any gastrointestinal symptoms during the interictal period.MethodsWe enrolled 27 migraine patients, 32 FD patients and 12 healthy people as controls, and performed GE scintigraphy as gastric function test. Gastrointestinal symptoms were evaluated in the FD and migraine.ResultsThe age-adjusted mean gastric half-emptying time in FD (125.51 ± 52.55 minutes) patients was longer than in migraineurs (100.82 ± 23.94 minutes, P = 0.035) and controls (95.25 ± 23.29 minutes, P = 0.021). The percentage of gastric retention was higher in FD than in migraine. However, migraineurs did not show an obvious delayed gastric emptying or an increase of gastric retention when compared to the normal controls. The association between each dyspeptic symptom and GE parameters was not significant, but postprandial fullness and early satiety showed a tendency of delayed GE. In migraineurs, GE time did not show significant association with nausea and vomiting during interictal periods.ConclusionsDelayed GE does not appear to be a mechanism that patients with FD and migraine have in common. Migraineurs without dyspepsia during interictal period had normal GE, and further study for association with FD should be investigated.
For the halide-free imidazolium-based ionic liquids with a methanesulfonate anion, the solubility results of carbon dioxide (CO 2 ) are presented at pressures up to approximately 45 MPa and temperatures ranging from 303.15 K to 343.15 K. The solubility was determined by measuring bubble pressures of mixtures of CO 2 and ionic liquid using a high-pressure equilibrium apparatus equipped with a variable-volume view cell. The ionic liquids studied in this work were 1,3-dibutylimidazolium methanesulfonate, 1-ethyl-3-methylimidazolium methanesulfonate, 1-butyl-3-methylimidazolium methanesulfonate, and 1,3-dimethylimidazolium methanesulfonate. A sharp increase of equilibrium pressure was observed at high CO 2 compositions. In ionic liquids, the CO 2 solubility was elevated according to the increase of the total length of alkyl chains linked to the imidazole of the ionic liquids, and this increase became more apparent at higher pressures. The ionic liquids with a methanesulfonate anion gave a lower CO 2 solubility than the ionic liquids with a fluorinated substituent such a fluoroalkyl group on their anions.
Background: A paradoxical response is defined as the radiological and clinical worsening of a previous lesion or the development of new lesion after initial improvement during theprocess of antituberculous treatment. The related factors for the development of a paradoxical response in patients with tuberculous pleurisy are not certain. Methods: We selected patients with tuberculous pleurisy who had been treated for more than 4 months. The changes onthe serial chest X-ray findings before and after treatment were reviewed. Paradoxical responses were regarded as any worsening or development of new lesion at least 2 weeks after the initiation of treatment. The baseline clinical characteristics and laboratory findings of the peripheral blood and pleural fluid were compared between the patients with a paradoxical response and the patients without a paradoxical response. Results: Paradoxical responses appeared in sixteen patients (21%) among the 77 patients.It took a mean of 38.6 days after the treatment and the time to resolve the paradoxical response was a mean of 32.1 days. For the patients with a paradoxical response, the median age was younger (30.5 years vs 39.0 years, respectively) and the lymphocytic percentage of white blood cells in the pleural fluid was higher (82.1% vs 69.6%, respectively) than for the patients without a paradoxical response. Conclusion: The development of a paradoxical response during the treatment of patients with tuberculous pleurisy was not rare and this was related with the age of the patients and the percentage of lymphocytic white blood cells in the pleural fluid.

The caudate lobe often exhibits enlargement and nodularity in cases of cirrhosis, which makes differentiation of hepatocellular carcinoma from other masslike lesions of the caudate lobe difficult in cirrhotic patients. A 12×6 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.
