RESUMEN
CT scans of 23 patients with gallbladder carcinoma were retropectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes around the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35%. The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.

Castleman disease is a relatively rare disease of differential diagnostic interest in patients with lymphadenophathy. The etiology and pathogenesis of the Castleman disease are still not elucidated and the MRI findings of disease has not yet been reported. Two patients with Castleman disease studied by MRI are presented: one case presented with a localized anterior mediastinal mass and the other case, with a neck mass. The lesions were characterized by relatively high signal intensities on both T1 and T2 weighted images in both cases, and significant degree of enhancement was seen in the cervical Castleman disease.

Asphyxia is the most important perinatal cause of neurologic morbidity in infants. Recently, elevated levels of CK-BB have been demonstrated in serum after asphyxic insult in infants. To evaluate the possibility of using serial measurements of CK-BB activity as a diagnostic method and a predictor of neurologic outcome in asphyxiatic infants. We studied CK-BB activity in serum of asphyxiated infants (16 preterm babies, 41 term babies) and healthy infants (11 preterm babies, 12 term babies) from birth (cord) to 5 days of serially. The results were as follows 1) Serum CK-BB activites (cord 76.0IU/L, 12 hours 34.1 IU/L, 1 day 22.4 IU/L, 2 days 8.2 IU/L) of asphyxiated preterm infants were much higher than those (cord 4.4IU/L, 12 hours 2.4IU/L, 1 day 1.6 IU/L, 2 days 1.1 IU/L) of healthy preterm infants, but there were no significant differences (P values>0.05). 2) Serum CK-BB activities (cord 59.0 IU/L, 12 hours 23.6 IU/L, day 17.6 IU/L) of asphyxiated term infants were significantly higher than those (cord 2.4 IU/L, 12 hours 2.7 IU/L, 1 day 0.4 IU/L) of healthy term infants (P values0.05) 4) Serum CK-BB activity (131.7 IU/L) at birth (cord) of asphyxiated term infants who showed late neurologic deficits was significantly higher than that (49.8 IU/L) of asphyxiated term infants who did not show late neurologic deficits (P value<0.05) In conclusion, it is suggested that serial measurement of CK-BB activity in serum of asphyxiated term infants from birth (cord) to 1 day of age is an available test for diagnosis of neonatal asphyxia and for a prediction of neurologic outcome of neonatal asphyxia.

An echogenic lobulated round mass in the head of pancreas was found during abdominal ultrasonography for routine checkup on a 34 year-old man. CT and MRI showed characteristic findings of lipoma. Clinical followup confirmed intrapnacreatic lipoma, which had been reported only once proviously. This lesion should be added to the list of benign connective tissue tumor of the pancreas.

We report a case of metastatic signet ring cell carcinoma of the ureter, The patient a 50-year-old man, presented with pain in the left flank. Radiologic examination revealed partial obstruction in the mid-portion of the left ureter. Microscopically, numerous signet ring cells were infiltrated in the muscle and serosa. Although multiple bone metastases were noted, the primary site was not identified after complete clinical examination in this case, which is unique to us and may be of interest to others.
