  • Objective: To compare the diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3-tesla (3T) magnetic resonance imaging (MRI) and computed tomography (CT) for the detection of visceral pleural surface invasion (VPSI). Visceral pleural invasion by non-small-cell lung cancer (NSCLC) can be classified into two types: PL1 (without VPSI), invasion of the elastic layer of the visceral pleura without reaching the visceral pleural surface, and PL2 (with VPSI), full invasion of the visceral pleura. Materials and Methods: Thirty-three patients with pathologically confirmed VPSI by NSCLC were retrospectively reviewed. Multidetector CT and contrast-enhanced 3T MRI with a free-breathing radial three-dimensional fat-suppressed volumetric interpolated breath-hold examination (VIBE) pulse sequence were compared in terms of the length of contact, angle of mass margin, and arch distance-to-maximum tumor diameter ratio. Supplemental evaluation of the tumor-pleura interface (smooth versus irregular) could only be performed with MRI (not discernible on CT). Results: At the tumor-pleura interface, radial VIBE MRI revealed a smooth margin in 20 of 21 patients without VPSI and an irregular margin in 10 of 12 patients with VPSI, yielding an accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and F-score for VPSI detection of 91%, 83%, 95%, 91%, 91%, and 87%, respectively. The McNemar test and receiver operating characteristics curve analysis revealed no significant differences between the diagnostic accuracies of CT and MRI for evaluating the contact length, angle of mass margin, or arch distance-to-maximum tumor diameter ratio as predictors of VPSI. Conclusion: The diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3T MRI and CT were equal in terms of the contact length, angle of mass margin, and arch distance-to-maximum tumor diameter ratio. The advantage of MRI is its clear depiction of the tumor-pleura interface margin, facilitating VPSI detection.

  • An adult one-year-old male Eurasian beaver (Castor fiber) died of a traumatic injury to its right leg from a fall. At necropsy, fibrinopurulent exudates were observed in the thoracic cavity. Histopathologic examination showed that the pericardium, thoracic wall, pulmonary pleura and the lungs were markedly thickened due to mixtures of necrotic cellular debris, neutrophils, fibrin, red blood cells, and bacterial aggregates. Pure culture of Klebsiella (K.) pneumoniae was isolated from the thoracic exudates, pleura and heart tissues. Based on these findings, this is the first report describing pleuritis and pericarditis associated to K. pneumoniae in a beaver.

  • Excision of bullous emphysema or decortication of chronic empyema commonly results in a prolonged air leakage. Prolonged air leakage requires prolonged intercostal drainage, delays recovery, and can be followed complications such as pneumothorax, atelectasis, incomplete expansion of remained lung, secondary infection. To minimize these complications free muscle grafts can be used like a patch to close the opening of visceral pleura and reinforce suture lines without undue tension. From a preliminary study using the latissimus dorsi muscle as a free muscle graft in the rabbit pleural space, viable muscle fibers that seems the result of the process of regeneration can be consistently identified around the degenerating muscle fibers. Voluminous connective tissues and numerous blood vessels are also observed in the peripheral zone. Further studies in that free muscle graft will be sutured with visceral pleura and lung parenchyme will hopefully provide additional information before clinical application.

  • A solitary fibrous tumor in the pleura has been reported occasionally, but extremely rare in themediastinum. The histogenesis of this tumor has been still in controverse, but recent studies paid attention to it a mesenchymal origin by the immunohistochemical and ultrastructural bases. A few cases, reported in the literature, suggest that the mediastinal solitary fibrous tumor occurs more commonly in adult and shows slightly higher incidence in women. Its aggressive behavior such as recurrence rate and distant metastasis, is more prominant than reported in solitary fibrous tumor of the pleura. No single histologic feature allows an assumption definite prognosis. Surgical resection of this tumor is usually curative although the recurrence or distant metastasis are reported in about half of the patients. This report is a case of solitary fibrous tumor in the mediastinum in a 16-year-old female patient.She underwent surgical resection and her postoperative result was satisfactory.

  • A dead, female, 3 years old, squirrel monkey (Saimiri sciureus) was submitted and examined. Before death the monkey has showed lethargy, recumbency and inappetence since November 14, 2001 and died in November 17. Grossly much fibrin was deposited on the pleura of right lung, pericardium, and diaphragm(pleural part). And reddening of right lung was seen. Histopathologically lung showed severe fibrinous pleuritis, severe edema, thrombosis, and focal necrosis in parenchyma. Also much fibrin and mononuclear cells were deposited on the pericardium. In bacterial culture on the pleura and parenchyma of lung, and pericardium, B. bronchiseptica was isolated. Therefore we confirmed this case as the fatal case by B. bronchiseptica in squirrel monkey.

  • A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step.

  • Pulmonary bullae usually grow slowly and have thin walls. However, we have observed 2 cases of abrupt bulla formation immediately after lobectomy and during surgery. The pathologic findings of what can be called visceral pleural detachment are quite distinctive: these bullae had a broad base connected to the lung, and their walls were thick, including the full extent of visceral pleural and peripheral alveolar tissues, which suggests that the visceral pleura were detached from the distal alveoli. High transpleural pressure might be the key factor in the pathogenesis of this type of bulla, unlike previously known types of bullous lung disease.
