Contrast extravasation in hyperacute intracerebral hemorrhage (ICH) indicative of active bleeding is a predictor of possible enlargement of hematoma, providing clinician with valid management decisions. We report unusual MR imaging features of contrast extravasation in hyperacute ICH in three patients: Case 1 with hypertension revealed dual foci of contrast extravasation, one in right basal ganglia and the other in left lateral ventricle, suggesting simultaneous bleeding of the two foci. Case 2 with presumed diagnosis of vasculitis showed relatively large area of contrast extravasation mimicking enhancing tumor or vascular lesion. Case 3 with hypertension showed the findings of active bleeding which was likely to occur during the time of MR imaging acquisition.

Background: We present here the early and midterm surgical results for infective endocarditis and we especially focus on the effect of aggressive reconstruction or root implantation after wide debridement. Material and Method: Between January 1995 and Jun 2006, we enrolled 79 adult infective endocarditis patients who underwent surgical treatment. There were 63 and 16 native and prosthetic valve endocarditis cases, respectively. They included 27 cases of culture negative endocarditis. With performing valve replacement or repair, 28 of the patient underwent a more aggressive surgical option, for example, aortic root replacement or reconstruction, or heart base reconstruction etc. Result: There were statistical relationships between the in-hospital mortality and staphylococcal infection, urgent-based operation and operation during the active phase of endocarditis. Wide debridement and aggressive reconstruction were not related to either the post operative mortality or the early morbidity. Culture negative endocarditis was not related to the postoperative mortality and morbidity. Conclusion: Physicians must pay attention to patients' medical treatment during the preoperative period of the infective endocarditis. If surgery is considered for treating infective endocarditis, it should be performed before the downhill course of the disease so that the surgical outcome is improved. Wide debridement and more aggressive reconstruction are also warranted.

Hughes-Stovin Syndrome is an exceedingly rare combination of distal pulmonary arterial aneurysm and deep vein thrombosis, mostly found in young patients. There are striking similarities between the vascular manifestation of Behçet's disease and Hughes-Stovin Syndrome. It has been suggested that they may have a similar pathogenesis. Most patients died of massive hemoptysis due to rupture of aneurysm. Recently we have experienced the first case of Hughes-Stovin Syndrome in Korea. A 37 year old male patient was admitted because of recurrent hemoptysis and intermittent fever. He had a history of recurrent aphthous ulcers and erythema nodosum-like skin rash, But no other findings of Behcet's disease was found. Angiography showed multiple pulmonary arterial aneurysm and deep vein thrombosis in Right lower extremity. Histologic examination of specimens of open lung biopsy revealed leukocytoclastic angiitis. Pulmonary arterial aneurysms were successfully treated by coil embolization and he is in good condition with corticosteroid and cyclophosphamide therapy.

A 26-year-old man with a one-year history of asthma and sinusitis presented with bilateral pleural effusions, patch basilar infiltrates on a chest x-ray and a pericardial effusion on an echocardiogram. The peripheral blood showed marked eosinophilia. An obstructive pattern was also observed during the pulmonary fuction test, which was responsive to bronchodilator inhalation. Nerve conduction studies showed right sural neuropathy. Thoracentesis yielded an acidotic exudative effusion with low glucose, low $C_3$ and eosinophilia. An open lung biopsy revealed an eosinophilic interstitial pneumonitis associated with a necrotizing eosinophilic vasculitis, and granulomatous inflammation foci. In the literature, pleural effusions were reported in 29 percent of Churg-Strauss patients, but the number of effusions was low and their characteristics have not been well described. This report describes the characteristic findings of pleural fluid and its histologic features in a case of classical Churg-Strauss syndrome.

Behcet's disease is a complex multisystem disease that features recurrent aphthous stomatitis, recurrent genital ulcerations, and eye lesions(uveitis or chorioretinitis). Among the systemic manifestations, pulmonary involvement is known to be rare and only a few cases have been documented. The most important features of pulmonary lesions in Behcet's disease are recurrent hemoptysis, which is often massive, and fatal pleuritic chest pain and recurrent high fever and fleeting nature of the pulmonary infiltrates. We report a case of Behcet's disease manifestated as high fever and pleural effusions which was complicated by pulmonary infarction as a result of pulmonary arteritis.

A 14-year-old intact male Siberian Husky was presented with hematuria, lethargy, and anorexia of 1-month duration. The physical examination revealed mild abdominal distension and pain. The hematology and serum chemistry revealed anemia and severe azotemia. The radiographic examination revealed renomegaly and the ultrasonographic examination, indistinct cortico-medullary junction, increased renal cortex echogenicity, and irregular margination. The urinalysis showed proteinuria and hematuria. The differential diagnosis included renal failure, cystitis, pyelonephritis, and neoplasia. The patient's condition continued to deteriorate, and the dog eventually died. The gross findings from the necropsy revealed hemoperitoneum and a bilateral renal mass. HSA was diagnosed by histopathological examination. This case report describes primary bilateral renal hemangiosarcoma (HSA), which is uncommon in dogs.

Descending necrotizing mediastinitis(DNM) is a rare complication of the oropharyngeal and cervical infection. Descending necrotizing mediastinitis requires an early and aggressive surgical approach to reduce the high morbidity and mortality associated with this disease. A 39-year-old man complained of odynophagia, neck swelling, and disturbance of swallowing with dyspnea. CT scans of the neck suggested a peritonsillar abscess and retropharyngeal and peripharyngeal abscess. He underwent cervical drainage. He remained febrile and complained of severe both pain in both shoulders. On postoperative day 5, a follow-up CT scan confirmed a mediastinal abscess. Reexploration of the neck and right thoracotomy for debridement and drainage of the mediastinal abscess were performed.. A large amount of pus was drained from the anterior and posterior mediastinum and its necrotic tissue was debrided. The patient's condition and radiologic findings gradually improved. Cultures of the drain fluid revealed Klebsiella pneumoniae. He was discharged on the 85th hospital day. In our experience, both transcervical drainage and aggressive mediastinal exploration via thoracotomy can lead to an improvement in the survival of the patient with descending necrotizing mediastinitis. CT scanning is useful for early diagnosis of mediastinitis and for follow up.

This is a report of a successful management of a patient with infective endocarditis involving native aortic valve, mitral valve, tricuspid valve, and Interventric lar septum. A 16 year-old patient who underwent VSD patch closure, and aortic valvuloplasty at the age of 1 1 years showed Intractable congestive heart failure during antibiotics treatment for infective endocarditis. Operative findings revealed that there were large defect along the previous patch, aortic regurgitation with multiple perforations and vegetations, mitral regurgitation with vegetation, aortic paraannular abscess, interventricular myocardial abscess, and tricuspid regurgitation with perforations and vegetations. We reconstructed the interventricular defect with Dacron patch extending to the aortic valve annulus after radical debridement of all infected or devitalized tissues, and could implant aortic valve by anchoring to the reconstructed Dacron patch. Mitral valve was replaced and tricuspid valve was repaired with patient's own pericardium. The patient was discharged after antibiotics treatment for 6 weeks and in good condition without any sequelae for 12 months.

Pericardial abscess due to liver abscess is a very rare disease, the result of which is usually fatal when untreated. But a combination of antibiotics therapy and pericardial drainage has broug t good result. A 32-year-old man was admitted to the emergency room because of fever and chilling sensation. Chest X-ray showed cardiomegaly and a mass lesion In the left lobe of liver on ultrasonography. The echocardiography revealed impending cardiac tamponade. Pus drainage of the liver abscess through per- foration of right diaphram and pericardiotomy were performed. The pericardium was thickened and 600 ml of purulent fluid and necrotic debris were drained. Fibrin clots were firmly attached to the undelying myocradium. Histological examination of the pericardium showed acute inflammation with microabsscess and Escherichia soli was cultured from pericardial pus. He was discharged after 4 weeks on antibiotics, but Doppler echocardiograpy revealed a slightly thickened pericardium with a mild constrictive physiology.

Some tricuspid valve endocarditis can be controlled effectively with specific antibiotic treatment. However, surgical intervention Is necessary when there are continuing sepsis, moderate or severe heart failure, multiple pulmonary emboli, and echocardiographycally demonstrated vegitations. We are repoting a 19 year-old male patient who was admitted for the treatment of infective endocarditis. He previously had an operation for ventriculer septal defect (perimembranous type) about 9 years ago . An echocardiogram showed a large vegetation on the anterior cusp area and a left to right shunt through VSD, which was previously closed with dacron patch. A valve replacement in addition to antibiotic therapy was recommended for the patient. The patient underwent on operation : tricuspid valve replacement was done with 51. Jude medical valve prosthesis (33 mm), and in addition to above procedure, removal of vegetation and direct closure of VSD were done Postoperative echocardiogram showed that replaced tricuspid valve functioned well and vegeta ion and shunt flow were not observed. The patient recovered without complication and discharged at Postoperative day 25. Early aggressive surgical intervention is indicated to optimize surgical results, and this case seems to be a typical right sided bacterial endocarditis, which is caused by residual VSD. We are reporting a case of tricuspid valve endocarditis with a review of the literature. (Korean J Thorax Cardiovasc Surg 1996 ; 29: 440-3)
