We report a familial case of visceral larva migrans of Toxocara canis after eating raw chicken liver. A 9-year-old female ate raw chicken liver with her father and older brother and was admitted to the hospital with periumbilical pain, a mild fever, and headache. The total peripheral eosinophil count was 9,884/$mm^3$ and the total lgE concentration was 2,317 IU/dL. Chest and abdominal computed tomography (CT) scans demonstrated multiple, poorly-defined, small, nodular lesions scattered in the liver and lung parenchyma. Toxocara ELISA and Western blot tests were positive in the patient, and her father and brother. A liver biopsy revealed extensive eosinophilic infiltrations in the portal and lobular areas. She took albendazole for 5 days and was discharged in good condition. These results suggest that clinicians should consider foodborne toxocariasis in patients with multiple, small nodules in the liver and lung parenchyma with eosinophilia and a history of raw meat ingestion.

Endoscopic subureteral injection for treatment of vesicoureteral reflux (VUR) is known to be safe and efficient due to its minimal invasive nature. Being non-migratory, non-antigenic, and biocompatible, Macroplastique (Polydimethylsiloxane) is likely to be stable over time. A 5-year-old boy with a past history of subureteral administration of Macroplastique for unilateral Grade V VUR 4 years ago presented with recurrent gross and microscopic hematuria, along with suprapubic pain. On computed tomography (CT) abdomen, calcified material, suspected to be a stone, was visualized in the bladder. On diagnostic cystoscopy, calcification was seen around the orifice site where Macroplastique injection had been performed. We removed the calcific material by Holmium laser. Endoscopic subureteric implantation has several advantages, but nevertheless, vigilance is needed to detect long-term complications, especially in patients with gross or microscopic hematuria.

Duodenal web is an uncommon lesion that infrequently cause partial or complete intestinal obstruction. If the duonenal web is incomplete and only partially obstructs the duodenal lumen, the onset of symptoms may be delayed for years, and obstructive symptoms will be only minimal and intermittent. Congenital duodenal obstruction is occasionally associated with intestinal malrotation. We experienced a case of duodenal web associated with intestinal malrotation in a 9-year-old girl who had been suffered from intermittent projectile vomiting since birth without failure to thrive. The diagnosis was made by UGI series & abdominal CT. Patient remained asymptomatic after operation.

Pancreatoblastoma is uncommon in children and is exceedingly rare in adults. Prognosis is good if the tumor is removed prior to metastasis. Complete tumor resection is the most important factor for long survival. We report two cases of pancreatoblastoma in 4 and 7 years old girls. Palpable abdominal mass was accidentally found by their parents. Abdominal CT scan showed a huge retroperitoneal mass of unknown origin in one case and a mass involving the pancreas in the other case. At laparotomy, well encapsulated tumor mass($10{\times}10$ cm in maximum dimension) was noted in the body of pancreas in one case, and in the tail of pancreas in the other case( $8{\times}7$ cm). We resected the tumor and preserved the spleen in both cases. Histological examination revealed that the tumors were pancreatoblastoma. Patients received postoperative chemotherapy with 6 cycles of cisplatinum, adriamycin, ifosfamide and etoposide and are alive in good condition 19 months and 17 months after operation.

Sialoblastoma is a rare tumor of salivary gland origin, developing in the fetal or neonatal period. Most tumors arise in parotid gland, and rarely in submandibular gland. Because of its rare incidence, diagnosis of the sialoblastoma in head and neck tumors of children is not easy. The case of a congenital submandibular gland sialoblastoma is presented. A neonate was transferred right after birth due to a submandibular mass. CT scan showed a lobulating mass located posterior to the left submandibular gland, suggesting neurogenic tumor or myofibroma. The tumor was excised easily after division of a duct-like structure connecting with the submandibular gland. The microscopic findings showed the basaloid cells and ductules forming cellular nests, separated by thin fibrous tissue. Immunohistochemical staining was positive for cytokeratin, vimentin and Ki-67, which was consistent with sialoblastoma.

This is a case of tracheomalacia associated with esophageal atresia. An 11-month-old- male boy presented with a life-threatening apneic spell after correction of esophageal atresia (Gross type C). After complete exclusion of the other possible causes of the apneic spell, the presumptive diagnosis of tracheomalacia was made with fluoroscopy and 3-dimensional chest CT. The final diagnosis was made with rigid bronchoscopy under spontaneous respiration. The aortopexy was performed with intraoperative bronchoscopic examination. The postoperative period was unremarkably uneventful. The patient was discharged 9 days after the aortopexy and has remained well to date (5 months after the aortopexy).

Intussusception is a frequent cause of intestinal obstruction in early childhood and most are idiopathic in origin. In a minority of cases a definite pathological lead point is identified by imaging studying or during surgery. As the pathologic lead point of intussusception, Meckel's diverticulum is the most common lesion. In symptomatic patients, 40~60% of Meckel's diverticulum contain ectopic tissue, with gastric mucosa being far the most common type. A few Meckel's diverticulum contain pancreatic tissue. Combined heterotopic pancreatic and gastric tissues in the Meckel's diverticulum especially causing intussusception is extremely rare. We report the case of 5-year-old girl with an intussusception caused by Meckel's diverticulum containing both heterotopic gastric and pancreatic tissues.

Perinephric abscess is an accumulation of pus in the perinephric space, the area anatomically defined between the kidney and Gerota's fascia. Gram negative organisms are the most prevalent bacterial species found in perinephric abscess. Fever, flank pain, vomiting and abdominal mass are the usual presenting complaints. But with its insidious onset, variable symptoms and rue frequency in children, perinephric abscess has been a major diagnostic problem, leading to delayed diagnosis and inappropriate treatment, which increase the rate of complication and mortality. Clinical diagnosis of perinephric abscess is difficult but must always be considered in children with a febrile septicemic illness. For appropriate treatment, early detection is very important, and either ultrasonography or computed tomography(CT) facilitates the diagnosis and establishment of treatment method. We experienced a case of left perinephric abscess treated by percutaneous drainage in a 1-year 7-month old boy. Review of literature was made briefly.

Posterior nutcracker phenomenon (PNP) was found to be the cause of significant proteinuria in a 10-year-old female. PNP was documented by Doppler ultrasonography and abdominal 3D CT as a cause of her proteinuria. Despite treatment with ACE inhibitor for several months, her persistent and progressive proteinuria lead us to perform a left renal biopsy, which revealed no significant finding except for focal effacement of foot processes. We speculate that nutcracker phenomenon can induce not only orthostatic proteinuria but also significant proteinuria by focal effacement of foot processes.

Kawasaki disease (KD) is a leading cause of acquired heart disease in children. Yet the etiology of KD is still unknown and diagnosis depends on the exclusion of other diseases and the clinical manifestations meeting the defined criteria. Young infants frequently show atypical clinical courses and are frequently complicated with coronary aneurysms. Some cases show thrombocytopenia, which is known as one of the risk factors for complications with coronary aneurysms. So, a high index of suspicion is the most important factor for the diagnosis of KD in very young infants or adolescents whose clinical courses are equivocal. We report herein on a case of KD in an 80-day-old female infant with fever and seizure with bloody stool; laboratory findings were those of sepsis with disseminated intravascular coagulopathy. In spite of aggressive treatments, fever and thrombocytopenia persisted for two weeks and huge coronary aneurysms developed at the third week in all three major coronary arteries; the diameter of the right one was as large as the aortic annulus. Three months later, huge pulsatile masses developed in both axillas; these were found to be huge axillary aneurysms defined very clearly on multi-detector CT scan. She has been under follow up with antiplatelets and anticoagulation therapy with poor regression of the aneurysms.
