Objective. To evaluate efficacy of diagnostic procedures, results of surgery, and complications in malignant pleural diseases. Material and methods. From 1999 to 2006, 169 patients underwent treatment in the Department of Thoracic Surgery and Oncology, Institute of Oncology, Vilnius University. Patients were divided into two groups: group I, patients with primary pleural malignant diseases (93 patients, 55.0%), and group II, secondary pleural tumors (76 patients, 45%). Of the 76 patients, 40 patients (52.6%) were diagnosed with metastatic pleural tumors and 36 patients (47.4%) with tumors invading parietal pleura. We used noninvasive and invasive methods for diagnosis. Noninvasive methods included chest x-ray, chest computed tomography, magnetic resonance imaging, chest ultrasound, positron emission tomography/ computed tomography (performed in Germany), and invasive methods included puncture of pleural effusions, transthoracic pleural puncture, drainage, pleural biopsy and video-assisted thoracoscopic pleural biopsy, pleural resection, and ultrasound-guided needle biopsy of the pleura. The following procedures were performed in group I: pleurectomy in 15 patients (16.1%), pleural pneumonectomy in 42 patients (45.2%), pleural decortication in 12 patients (12.9%), extended pleuropneumonectomy with diaphragm and pericardium resections and plastic surgery in 14 patients (15.0%), pleurectomy with costal resections in 10 patients (10.1%). Procedures performed in group II included video-assisted thoracoscopic pleurectomy in 15 patients (19.7%), pleural biopsy in 10 patients (13.2%), pleurectomy in 15 patients (19.7%), pleural drainage and fenestration in 5 patients (6.5%), lung and pleura resection in 12 patients (15.8%), chest wall and pleura resection in 10 patients (13.2%), diaphragm and pleura resections in 9 patients (11.8%). Results. Early stage primary pleural tumors were found in 24 patients (25.8%). Metastatic pleural disease was found in 32 patients with early primary tumors (80.0%). In all 36 patients (100.0%) with chest wall tumors, disease of advanced stage was determined. Main surgical complications of the group I were observed in 26 patients (27.9%). Six patients (6.5%) died after surgery. In group II, 23 patients (30.2%) had postoperative complications; 3 patients (3.9%) died. Conclusions. In noninvasive methods, the highest sensitivity was achieved for chest computed tomography and magnetic resonance imaging (97%); the specificity of chest magnetic resonance imaging was 100%, and the specificity chest computed tomography and magnetic resonance imaging – 98%. The accuracy of chest xray plus computed tomography was 98%. In invasive methods, accuracies of pleural biopsy, video-assisted thoracoscopic pleural biopsy, and pleurectomy were 100%, 90%, and 100%, respectively. In case of primary pleural tumors, the main surgery was extended pleuropulmonectomy (45.2%) with or without mediastinal resection. Mortality rate was 6.5%. In case of metastatic pleural disease, the main surgery was video-assisted thoracoscopic pleurectomy (19.7%). Mortality was rate 5%. In cases of pleural invasion by other thoracic malignancies, the main surgeries were chest wall and pleural resection (13.2%) and lung and pleural resection (15.8%). Mortality rate was 2.8%.

Abstract Background Desmoplastic fibroblastoma is an uncommon, benign, fibrous tumor exhibiting infiltrative growth. Most of these tumors are small, slow-growing, and develop as subcutaneous lesions in the extremities. Cases of desmoplastic fibroblastoma in the chest wall are quite rare, and the preoperative diagnosis of such cases remains challenging as these tumors can mimic the characteristics of desmoid-type fibromatosis, which often occurs in the chest wall. We aimed to describe a rare case of desmoplastic fibroblastoma exhibiting rapid growth in the chest wall of a patient that was successfully treated with marginal excision only by diagnostic imaging before surgery. Case presentation A 79-year-old man was admitted to our hospital after experiencing right shoulder pain lasting for a few months. A 4 × 4 × 2 cm mass was incidentally detected at the right second rib two years prior. Chest computed tomography revealed a well-defined homogeneous mass with a muscle-like density along the right lateral chest wall, the size of which had increased to 12 × 10 × 4.5 cm in two years. Dynamic contrast-enhanced computed tomography revealed abundant vascularity at the periphery of the tumor. Magnetic resonance imaging revealed iso-intensity to muscle on T1-weighted images, slightly high intensity on T2-weighted images, and rim-like contrast enhancement at the periphery of the tumor, with uniform thickness on gadolinium-enhanced T1-weighted images with fat suppression. Rim-like contrast enhancement is an imaging feature that can distinguish cases of desmoplastic fibroblastoma from desmoid-type fibromatosis. We diagnosed the tumor as desmoplastic fibroblastoma by diagnostic imaging without tissue biopsy. Marginal excision with videoscopic assistance was performed through a small incision. The pathological diagnosis was desmoplastic fibroblastoma. The patient’s postoperative course was uneventful, and his shoulder pain was relieved after the surgery. Conclusions Desmoplastic fibroblastoma in the chest wall is extremely rare, but should be considered in the differential diagnosis when desmoid-type fibromatosis is clinically suspected. Gadolinium-enhanced magnetic resonance imaging is helpful in confirming the differential diagnosis.

AbstractDue to their important phylogenetic position among extant vertebrates, sharks are an invaluable group in evolutionary developmental biology studies. A thorough understanding of shark anatomy is essential to facilitate these studies and documentation of this iconic taxon. With the increasing availability of cross-sectional imaging techniques, the complicated anatomy of both cartilaginous and soft tissues can be analyzed non-invasively, quickly, and accurately. The aim of this study is to provide a detailed anatomical description of the normal banded houndshark (Triakis scyllium) using computed tomography (CT) and magnetic resonance imaging (MRI) along with cryosection images. Three banded houndsharks were scanned using a 64-detector row spiral CT scanner and a 3 T MRI scanner. All images were digitally stored and assessed using open-source Digital Imaging and Communications in Medicine viewer software in the transverse, sagittal, and dorsal dimensions. The banded houndshark cadavers were then cryosectioned at approximately 1-cm intervals. Corresponding transverse cryosection images were chosen to identify the best anatomical correlations for transverse CT and MRI images. The resulting images provided excellent detail of the major anatomical structures of the banded houndshark. The illustrations in the present study could be considered as a useful reference for interpretation of normal and pathological imaging studies of sharks.
