Fibrovascular polyp of the esophagus is a rare and benign pedunculated intraluminal tumor. The tumor consists of varying amount of vascular fibrous and adipose tissue that arises in the submucosa and is covered by squamous epithelium. We report the typical radiographic, CTand MR findings of a case of giant fibrovascular polyp of the esophagus.

BACKGROUND: Because of the common etiologic factor, such as smoking, lung cancer and chronic obstructive Pulmonary disease are often present in the same patient. The preoperative prediction of remaining pulmonary function after the resectional surgery is very important to prevent serious complication and postoperative respiratory failure. 99mTc-MAA perfusion scan has been used for the prediction of postoperative pulmonary function, but it may be inaccurate in case of large V/Q mismatching. We compared 99mTc-DTPA radioaerosol inhalation scan with 99mTc-MAA perfusion scan in predicting postoperative lung function. METHOD: Preoperative inhalation scan and/or perfusion scan were performed and pulmonary function test were performed preoperatively and 2 month after operation. We predicted the postoperative pulmonary functions using the following equations. Postpneumonectomy FEV1=Preop FEV1x% of total function of lung to remain RESULTS: 1) The inhalation scan showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.94, 0.91, 0.87 respectively). 2) The perfusion scan also showed good correlations between measured and predicted FEV1, FVC and FEF25-75%. (correlation coefficiency; 0.86, 0.72, 0.97 respectively). 3) Among three parameters, FEV1 showed the best correlations in the prediction by lung scans. 4) Comparison between inhalation scan and perfusion scan in predicting pulmonary function did not show any significant differneces except FVC. CONCLUSION: The inhalation scan and perfusion scan are very useful in the prediction of postoperative lung function and don't make a difference in the prediction of pulmonary function although the former showed a better correlation in FVC.

Chronic constrictive pericarditis is an uncommon disease, but an importanat one because of its potential curability. It usually begins with an initial episode of acute pericarditis often with a pericardial effusion which may not be detected clinically. This then progresses to resorption of the effusion followed by obliteration of pericardial abity with formation of fibrotic tissue, which results in symmetrical scarring that produce uniform restriction. In general, there are no specific problems due to remained pericardial effusion in the clinically manifestated case of constrictive pericarditis. We report a case of chronic constrictive pericarditis with localized pericardial effusion, which caused to hemodynamic compromise due to local compression of the right ventricle.

We aimed to evaluate the histologic components of primary mediastinal mixed germ cell tumors. A total of 221 patients diagnosed with a mediastinal germ cell tumor (GCT) were retrospectively reviewed. Among them, 14 patients underwent surgical resection after chemotherapy and 8 patients were diagnosed with mixed GCT, who were then selected for further evaluation. Clinical chart review and histologic review of biopsy and surgical specimens of 8 patients were performed. All 8 patients were young males and showed a mature teratoma or a mature teratoma with a focal immature teratoma in the resected specimens. Serum alpha-feto protein was variably elevated. Seven patients experienced an increase in tumor size after the chemotherapy. In 5 patients, a variable amount of vasculoconnective tissue was found along with the mature teratoma occupying average 66.3% of resected mass, and 3 of them showed an identical vasculoconnective component on biopsy before chemotherapy. We suggest that vasculoconnective tissue might be the intrinsic component of primary mediastinal mixed GCT. When vasculoconnective tissue is obtained on small biopsy of an anterior mediastinal mass of a young male, the possibility of underlying mixed GCT should be considered and further clinical work up should be performed.

Chordomas are slowly growing and rare malignant tumors arising from the remnants of the notochord. Furthermore, intrathoracic chordomas presenting as a posterior mediastinal tumor account for only 1~2% of all reported chordomas. Incomplete resection of these tumors can lead to local recurrence, distant metastasis and result in a poor outcome, but complete remission can be expected with complete resection and adjuvant radiotherapy. We report a case of thoracic chordoma presenting as a posterior mediastinal tumor which was successfully treated with complete resection and adjuvant radiotherapy without recurrence and distant metastasis for 2 years.

Postpneumonectomy syndrome is a rare condition characterized by dyspnea due to an extreme mediastinal shift and bronchial compression of the residual lung after a right pneumonectomy or a left pneumonectomy with the right aortic arch. Severe fibrosis of the lung such as tuberculsosis (TB) - destroyed lung can cause similar clinical features in the absence of pneumonectomy. We report a unique case of postpneumonectomy syndrome without pneumonectomy, which was successfully treated with pneumonectomy and mediastinal repositioning with tissue expanders.

Sternocostoclavicular hyperostosis is an uncommon disease, characterized by an inflammatory arthrosteitis of the sternocostoclavicular region. Clinically, it manifests as a painful swelling of the upper anterior chest wall, which is associated with occasional pustulosis palmaris and plantaris. A 48-year-old man had suffered from pain in both shoulders and the upper anterior part of the chest for 6 months. On examination, a venous engorgement in the neck with dilated collateral veins in the upper chest and shoulders was observed. Swelling was noticed in his face, neck and both arms. Radiologically, the clavicles, the sternum and the first ribs were enlarged with complete fusion between them. 99Tc scintigraphy showed increased uptake in the clavicles and the sternum. Selective venography resulted in a bilateral subclavian and brachiocephalic vein occulation, which resulted from a subclavian vein thrombosis. All the above suggested a sternocostoclavicular hyperostosis. He underwent a vascular graft interposition between the right jugular vein and the left innomianate vein (using 8mm ringed Gore-Tex graft) and a resection of the bilateral medial half of clavicle and 1st rib. Here, we present a case on sternoclavicular hyperostosis with subclavian and brachiocephalic vein thrombosis, and report this case study with a review of the appropriate literature.
