Hemangiopericytomas, which used to be classified as the subtype of the meningiomas, like the angioblastic meningiomas or hemangiopericytic meningiomas, are rare in the central nervous system with an incidence of <1% of all central nervous system(CNS) tumors. In spite of a total surgical removal, hemangiopericytomas have a tendency of high local recurrence and distant metastasis. The authors report a case of hemaniogipericytoma recurred at the remote area from the primary site. The tumor recurred in the meninges of right temporal area after total removal of the tumor in the right parasaggital region including the falx.

PURPOSE: To analyze the features of lacrimal drainage system obstruction confirmed during external dacryocystorhinostomy surgeries and report the surgical outcomes. METHODS: We reviewed the medical records of a total of 769 cases who underwent external dacryocystorhinostomy for primary lacrimal drainage obstruction between 2005 and 2014. Data about detailed location and extent of obstruction were collected intraoperatively. The sites of obstruction were classified into nasolacrimal duct obstruction (NLDO), common canalicular obstruction (CCO), and canalicular obstruction. Lacrimal sac mucosa and lumen were grossly inspected, and the frequency of lacrimal sac changes, such as significant inflammation or fibrosis, was analyzed in cases of CCO or canalicular obstruction. The surgical success rate was also evaluated including effect of lacrimal sac status in the CCO and canalicular obstruction groups. RESULTS: Of 769 cases, primary NLDO with patent canaliculi was diagnosed intraoperatively in 432 cases (56.2%), CCO in 253 (32.9%), and canalicular obstruction in 84 (10.9%). Of 253 cases with CCO, 122 (48.2%) showed clear lacrimal sac lumen, and the other 131 (51.8%) showed significant inflammation or fibrosis of the lacrimal sac. In cases with canalicular obstruction, 35 of 84 (41.7%) showed a clear lacrimal sac, and the other 49 cases (58.3%) cases revealed mucosal changes of the lacrimal sac. The functional success rate was 87.5% for primary NLDO, 75.5% for CCO, and 72.6% for canalicular obstruction. In the CCO group, the functional success rate was lower in cases with significant lacrimal sac change (p = 0.044). CONCLUSIONS: Even in patients with CCO or canalicular obstruction, a large number of cases have lacrimal sac changes, and those changes were associated with lower functional success rate.

Esophageal perforation continues to be associated with high mortality - 20% to 30% - despite advances in surgical techniques. Traditional surgery has been the mainstay of treatment for perforation, but recent advances in endoscopic closure devices has increased therapeutic options for selected patients. Our patient had a fishbone-induced esophageal perforation. He was treated successfully with endoscopic clipping, antibiotics and parenteral nutrition. We report this case and provide a review of the relevant literature.

True hermaphroditism in which both ovarian and testicular tissues are present in same individual is a rare abnormality. Abnormal differentiation of external and internal genitalia is also observed. A total of 30O cases found in the literature by Niekerk, V.A. During exp1oratory surgery, testicular as well as ovarian tissues are found generally. Authors experienced one case of true hermaphroditism who had an ovotestis on the right gonad an ovary on the left with a karyotype of 46, XX and report this case with the review of literatures.

The objective of this study is to define optimal diagnosis and treatment strategies for patients with urachal anomalies in the pediatric age group. The medical records of 21 children who had undergone surgery for urachal anomalies at Severance Hospital, Yonsei University College of Medicine from January 1990 to April 2005 were reviewed. The subjects included 14 males and 7 females (M:F 2:1). The four types of urachal anomalies confirmed were a urachal cyst in 10 patients (47.6%), a patent urachus in 6 (28.6%), a urachal sinus in 4 (19.0%) and a urachal diverticulum in 1 (4.8%) patient. The most common presenting complaint was umbilical discharge (n = 10, 40.0%), followed by abdominal mass (n = 9, 36.0%). Urachal anomalies were diagnosed by ultrasonography in 18 patients, and 7 of them were additionally examined by computed tomography. The remaining patients were diagnosed solely by surgical exploration. Excision was performed in all patients and was supplemented by partial cystectomy in three. Umbilical discharge was the most common clinical manifestation in our patients, suggesting that ultrasonography should be performed in patients with umbilical discharge to differentiate urachal anomalies. We found the most common anomaly to be the urachal cyst, and all patients were successfully treated by surgical excision.

BACKGROUND AND OBJECTIVES: Patent ductus arteriosus (PDA) is associated with increased morbidity and mortality in premature infants. Therefore, an early diagnosis and treatment of a hemodynamically significant PDA are very important. A widened pulse pressure is considered to be a well known clinical sign of a PDA in older infants and children; however, whether this is also applicable in the case of preterm infants remains to be confirmed. The aims of this study were to investigate the change in blood pressure (BP) before and after medical treatment of a PDA with indomethacin and to evaluate if the change in the pulse pressure in preterm infants with a medically treated PDA could be used as a reliable clinical predictor of a hemodynamically significant PDA. SUBJECTS AND METHODS: Between January 2005 and June 2009, a retrospective analysis was performed in preterm infants with a hemodynamically significant PDA (PDA group, n=72) and preterm infants without a PDA (control group, n=72) at the Chonnam National University Hospital Neonatal Intensive Care Unit. The PDA was closed by treatment with indomethacin. The BP was compared between the two groups over the seven days after the first dose of indomethacin. RESULTS: In preterm infants with a hemodynamically significant PDA, the mean systolic (55.1+/-6.0 mmHg) and diastolic BPs (31.4+/-6.2 mmHg) were lower than those in the controls (mean systolic BP 58.0+/-6.4 mmHg, mean diastolic BP 34.7+/-6.0 mmHg) before indomethacin treatment. When the ductus arteriosus was successfully closed by indomethacin treatment, there was a gradual increase in both the systolic and diastolic BPs without any change in the pulse pressure. CONCLUSION: The results of this study show that a widened pulse pressure is not a useful clinical sign of a hemodynamically significant PDA in preterm infants. However, low systolic and diastolic BPs may be useful clinical signs of a hemodynamically significant PDA in preterm infants. If the systolic and diastolic BP is low, a PDA should be considered and echocardiography should be performed for early diagnosis and treatment.

OBJECTIVE: This study is designed to demonstrate a relationship between reconstruction methods of the craniectomy site and the development of postoperative complications including headache, tinnitus, and operation site pain after microvascular decompression(MVD) in patients with hemifacial spasm. METHODS: This study included 44 consecutive patients who underwent MVD due to hemifacial spasm from 1995 to 2001. Craniectomy site was reconstructed with only Gelfoam(group 1) in 20, the bone dust and Gelfoam(group 2) in 11, the bone chips and Gelfoam(group 3) in 13. Group 1, 2 were studied retrospectively and group 3 was studied prospectively on the postoperative complications. RESULTS: Postoperatively, wound infection occurred in 3(6.8%), headache in 14(31.8%), operation site pain in 17(38.6%), tinnitus in 15(34.1%), hearing loss in 1(2.2%). Wound infection was noticed in 5% of group 1, 18.2% of group 2, and none of group 3. Headache developed in 45% of group 1, 27.3% of group 2, and 15.4% of group 3. Operation site pain was noticed in 50% of group 1, 27.3% of group 2, 15.4% of group 3. Tinnitus revealed in 45% of group 1, 18.2% of group 2, 30% of group 3. CONCLUSION: Reconstruction of the craniectomy site with the bone chips in patients with hemifacial spasm might have effects on diminution of the postoperative headache, operation site pain and wound infection.

The horseshoe Kidney is probably the most common of all renal fusion anomalies which often accompanies vascular anomalies and obstructive complications. Good post-operative results will be assumed with careful attention to the anatomy, vasculatures and drainge from renal pelvis at the time of operation. A 33 year old male was found to have horseshoe kidney with multiple renal stones, hydronephrosis and pyelonephritis. Through IVP, RGP, ultrasonogram, renal scan and renal angiography, the diagnosis was made. This is a report of the good results gained by isthmectomy, partial nephrectomy, ureterolysis and nephropexy.It was compared with several literature reviews.
