We report the case of a 17-year-old girl who presented with an indentation in the right ventricle caused by an incomplete pericardium on preoperative 3-dimensional reconstructed computed tomography. She was to undergo surgery for a partial atrioventricular septal defect and secundum atrial septal defect. Preoperative electrocardiography revealed occasional premature ventricular beats. We found the absence of the left side of the pericardium intraoperatively, and this absence caused strangulation of the diaphragmatic surface of the right ventricle. After correcting the lesion, the patient's rhythm disturbances improved.

Conjoined twinning is a rare congenital malformation, accounting for 1% of monozygotic twins. Conjoined twins result if twining is initiated after the embryonic disc and rudimentary amnionic sac have been formed and if division of the embryonic disc is incomplete. Recently we experienced a case of conjoined twins, dicephalus dipus dibrachius, who had died at 3 hours of life, and performed autopsy. Autopsy revealed a total duplication of the heads, spines up to sacrum, small bowels, thymus and lungs. Two hearts existed within a common pericardium.

In the 10 years from 1958 through 1968, 23 patients have undergone 24 times of operation for constrictive pericarditis at this department. Follow-up data were available for periods varying several months to almost 10 years from examination at this department or follow-up letters. There were 21 males and 2 females in this series. Range of the age varied from 2 years to 53 years. Seven cases were below 15 years of age. There were two hospital death, one expired two weeks and another four weeks after the pericardiectomy. In both of them, myocardial damage by disease process seemed to be major contributing factors. Clinical and histological study showed tuberculous origin in 12 cases, non-specific chronic infiammatory changes in 8 cases and in 3 cases previous pyogenic pericardial infection by staphylococcus preceded to the constriction. In 11 cases bone tissue was noted microscopically in the pericardium: Sixteen patients[70 %]had pleural effusions, five cases had bilateral, 6 right, and 5 left. Calcification was seen along cardiac border in 9 cases. In 15 catheterized patients, 6 showed pressure gradients between vena cava and right atrium, ranging from 6 mmHg to 10 mmHg. One case was reoperated 3 months after the original operation resulting in marked improvement. In this reoperated case the original pericardiectomy seemed to be incomplete. In 21 cases. excluding 2 hospital death, symptoms and physical findings improved markedly in every patient

Purpose : This study was conducted to analyze treatment outcome and prognostic significance of World Health Organization (WHO)-defined thymic epithelial tumor (TET) subtype and to assess optimal radiation target volume in patients receiving surgery and adjuvant radiation therapy with TET. Materials and Methods: The record of 160 patients with TET, who received surgical resection at the Samsung medical Center, from December 1994 to June 2004, were reviewed. 99 patients were treated with postoperative radiation therapy (PORT). PORT was recommended when patients had more than one findings among suspicious Incomplete resection or positive resection margin or Wasaoka stage $II\~IV$ or WHO type $B2\~C$. PORT peformed to primary tumor bed only with a mean dose of 54 Gy. The prognostic factor and pattern of failure were analyzed retrospectively. Results : The overall survival rate at 5 years was $87.3\%$. Age (more than 60 years $77.8\%$, less than 60 years $91.1\%$; p=0.03), Wasaoka stage (I $92.2\%$, II $95.4\%$, III $82.1\%$, IV $57.5\%$; p=0.001), WHO tumor type (A-Bl $96.0\%$, B2-C $82.3\%$; p=0.001), Extent of resection (R0 resection $92.3\%$, R1 or 2 resection $72.6\%$, p=0.001) were the prognostic factors according to univariate analysis. But WHO tumor type was the only significant prognostic factor according to multivariate analysis. Recurrence was observed in 5 patients of 71 Masoka stage I-III patients who received grossly complete tumor removal (R0, R1 resection) and PORT to primary tumor bed. Mediastinal recurrence was observed In only one patients. There were no recurrence within irradiation field. Conclusion : WHO tumor type was the important prognostic factor to predict survival of patients with TET. This study suggest that PORT to only primary tumor bed was optimal. To avoid pleura- or pericardium-based recurrence, further study of effective chemotherapy should be investigated.
