1 Mediastinal lymph nodes were usually hyperemic and enlarged.

2 Objective To study the CT appearances of mediastinal and retroperitoneal ganglioneuroma in children.

3 Chest or mediastinal radiation, bleomycin, or carmustine or lomustine therapy should have baseline lung function testing, then every 3-5 years as needed.

4 We present the first case of a mediastinal hemangiopericytoma with central calcification.

5 Methods 46 cases singlet hilum of lung and mediastinal lymphadenectasis were analyzed by normal chest CT and enhanced scanning of chest.

6 Significant mediastinal lymphadenopathy was seen in two patients (12%) with invasive thymoma, and nine patients (36%) with thymic carcinoma.

7 Conclusion The feature of mediastinal lymph node metastases in lung cancer may be saltatory and multiple.

8 Objective To explore the application value of mediastinal neoplasms excision outside of pleura.

9 Spontaneous subcutaneous with mediastinal emphysema is a rare but potentially dangerous complication during delivery.

10 Methods 10 patients with mediastinal tension emphysema were treated by mediastinotomy and drainage.

11 CT-pathologic correlation demonstrated that patterns of enhancement of mediastinal tuberculous lymphadenitis were correlated with distribution of granulation tissue and caseous areas.

12 We also can find pneumothorax, hydropneumothorax, mediastinal emphysema, subcutaneous emphysema,[] fracture of costal bone.

13 Spontaneous rupture of a huge mediastinal teratoma into the pleural cavity causing dyspnea is rare. A 14-year-old female presented with acute onset of severe chest pain, chills, fever, and dyspnea.

14 Mediastinal fibrosis is a rare late complication of histoplasmosis. It is characterized by invasive, calcified fibrosis centered on lymph nodes that block major vessels and airways.

15 Since the mediastinal teratoma has no specific symptoms, its definite diagnosis is difficult before surgical intervention.

16 Since mediastinal teratoma has no specific symptoms, its definite diagnosis is difficult before surgical intervention.

17 Results:17(34%)of 50 cases of mediastinal tumors showed returned pleural line. 39(78%) of them were thymoma, teratoma, retrosternal thyroid(), and neurogenic tumor.

18 Traumatic hemothorax caused by a ruptured mediastinal schwannoma is rare.

19 However, a mediastinal teratoma is rarely considered in a patient presenting with hemoptysis.

20 Such as mediastinal tumor, aortic aneurysm, goiter, heart, etc. increased.

21 It is typically reserved for patients who have contraindications to CT with iodinated contrast, for detailed assessment of mediastinal pathology, and for posterior fossa brain metastases.

22 Two clinically asymptomatic infants showed a suprarenal right-sided mass, one infant had a mediastinal tumour with tracheal compression causing immediate postnatal dyspnoea.

23 The chief cau - ses of distant metastasis were the lung and mediastinal nodes.

24 ResultsThe tumor included 4 invasive thymoma, 5 thymic cancer, 2 primary mediastinal small cell carcinoma.

25 Results On plain film, ME appeared as a line or lamellar radiolucent shadow; on HRCT, it clearly displayed as gas density shadow and gas-drawing-up mediastinal structure.

26 Objective:To access the value of CT in the qualitative diagnosis of mediastinal lymphadenectasis.

27 Under paragraph pericardial beside abdominal lymph nodes, even the supremacy of mediastinal shift upward or neck supraclavicular lymph nodes, lymph node showed lymphatic?

28 Herein, we report a 49-year-old female patient with malignant melanoma presenting as a mediastinal mass without an extrathoracic primary.

29 If supraclavicular adenopathy is noted, the patient should also be closely examined for hilar and mediastinal adenopathy.

30 We report herein a case of hemoptysis caused by a mediastinal teratoma with pulmonary involvement.

31 Hilar and mediastinal adenopathy can compromise regional structures such as the superior vena cava or trachea and potentially cause a life-threatening complication.

32 Methods:The imaging materials of 43 patients of mediastinal lymphadenectasis proved by operation, cervical lymph node biopsy and clinical treatment were analyzed.

33 The posterior portion of the capsule, called the mediastinum, contains blood and lymph vessels, nerves, and the mediastinal portion of the rete testis.

34 Results All were examined, suffering from local pneumothorax as indicated by CT, whose gases were located in prothoracicpart, back part, retrosternal part or near mediastinal part.

35 The way of covering the stumps of bronchi with mediastinal pleura could reduce the incidence of bronchopleural fistula.

36 Shortly after endoscopic retrograde cholangiopancreatography procedure , right - sided pneumothorax , subcutaneous, retroperitoneal, and mediastinal emphysema were noted.

37 Objective: To summarize the experience of treatment for mediastinal emphysema ( ME ) and analyse the etiopathology.

38 SEP has a better prognosis than solitary bone plasmacytoma (SBP) and MM. We report a patient with a mediastinal mass extending to the anterior chest wall without bony destruction.

39 Results Three dimensional imagings succeeded in 3 mediastinal uterines, 18 ovarian cystic cases, 6 of 10 uterine myomas[http:///mediastinal.html], 2 of 4 ovarian parenchymal masses and 7 of 10 tubal pregnancies.

40 Objective To study the CT diagnosis of mediastinal neoplasm oringinate in fibrous tissue and fibrous histocyte.

41 Follow-up MRI demonstrated a cystic structure consistent with a posterior mediastinal cystic hygroma and was atypical for both a neurenteric cyst and a duplication cyst.

42 Objective To investigate the clinical significance of systematic mediastinal lymphadenectomy in surgical treatment of non-small cell lung carcinoma.

43 Objective To study the diagnosis value of helical CT singlet hilum of lung and mediastinal lymphadenectasis.

44 The diagnosis was confirmed on chest X-ray which showed herniation of abdominal organs into the left hemithorax and mediastinal shift to the right.

45 Mediastinal lymph node enlargement is isible on soft tissue window scans.

46 PLC results from hematogenous spread to lung, with subsequent interstitial and lymphatic invasion, or, as in this case, direct lymphatic spread of tumor from hilar or mediastinal lymph nodes.

47 After partial or complete median sternotomy and division of the mediastinal fat in the midline, the internal thoracic artery and vein are palpated bilaterally but not dissected.

48 Methods 36 cases of mediastinal neoplasms were conducted excision of parasternal and vertebral column microtubule cut.

49 Objective To summarize the cause, diagnosis and treatment of mediastinal tension emphysema.

50 Results: Aneuploidy had statistic difference in lung carcinoma with lobulation, spiculate and mediastinal lymph node metastasis.

51 The cervical, mediastinal, and mesenteric lymph nodes were extremely enlarged, edematous and rarely congested.

52 OBJECTIVE : To analyse clinical diagnosis and prognostical factors of non - genital mediastinal seminoma.
