Computerized axial tomography (or computed tomography) scan is an x-ray procedure which combines many x-ray images with the aid of a computer to create cross-sectional or three-dimensional images of internal organs and structures within the body.
December 23rd, 2008. Advantages of multidetector-row CT with multiplanar reformation in guiding percutaneous lung biopsies
Conclusions: MDCT MPR images allowed sampling of pulmonary lesions until now considered unreachable with axial MDCT guidance because of overlying bony structures (ribs, sternum and scapulae) or critical location (hilar-mediastinal, proximity to the heart or large vessels). Compared with the conventional procedure, the use of MPR images does not increase the rate of pneumothorax or the procedure time.
December 23rd, 2008. Malignant mesothelioma
Compensation issues must also be considered. Life expectancy in malignant mesothelioma is poor, with a median survival of about one year following diagnosis.

December 17th, 2008. An autopsy case of sarcomatoid malignant mesothelioma mimicking adenocarcinoma with sarcomatoid elements of lung
Therefore, immunohistochemical staining was performed; the findings revealed sarcomatoid malignant mesothelioma. In conclusion, we encountered a rare case of sarcomatoid malignant mesothelioma (stage IV).
December 2nd, 2008. Monitoring of Chemotherapy Response in Malignant Pleural Mesothelioma Using Fluorodeoxyglucose Positron Emission Tomography
The tumor lesion exhibited shrinkage on CT and a decrease in the standardized uptake value (SUV) max after the first course of chemotherapy, but exhibited size enlargement and an increase in SUV max after the second course of chemotherapy. These findings suggest that results of quantification of metabolic response by FDG-PET are related to the objective response as determined by CT in patients with MPM.

October 22nd, 2008. A case of non-tuberculous mycobacteriosis with pleurisy with a past history of dense exposure to environmental asbestos
A final diagnosis of NTM was confirmed via open biopsy of the lung. Our case suggests that in addition to tuberculosis, NTM should be taken into consideration as a complication of silicosis.
October 22nd, 2008. A case of solid pseudopapillary tumour of the pancreas and malignant mesothelioma
Discussion: An abdominal computerised tomogram revealed pancreatic body mass arising. Pleural fluid cytology and a pleural biopsy failed to demonstrate malignancy. The pancreatic tumour was resected by distal pancreatectomy, segmental colectomy and splenectomy. The tumour was a solid pseudopapillary pancreatic tumour (SPT) with a high metastatic potential. The patient deteriorated and a repeat biopsy of the thickened pleura confirmed malignancy which was initially thought to be metastases from the SPT. Immunohistochemical staining confirmed malignant mesothelioma. The patient developed liver metastases and died 2 years from the diagnosis of metastatic disease.

September 19th, 2008. Preoperative staging of mesothelioma by 18F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography fused imaging and mediastinoscopy compared to pathological findings after extrapleural pneumonectomy
Conclusions: Non-curative surgery is avoided in 29% out of 42 MPM patients by preoperative PET/CT and in further 14% by mediastinoscopy. Even though both procedures are valuable, there are false negative findings with both, urging for even more accurate staging procedures.
September 17th, 2008. Peritoneal Mesotheliomas: Clinicopathologic Features, CT Findings, and Differential Diagnosis
Conclusion: The clinicopathologic features of peritoneal mesotheliomas vary among the subtypes such as malignant mesotheliomas, cystic mesotheliomas, and well-differentiated papillary mesotheliomas, and accordingly, there is a spectrum of CT appearances.
September 9th, 2008. Clinical consequences of asbestos-related diffuse pleural thickening: A review
It causes a restrictive defect on lung function and may rarely result in respiratory failure and death. Treatment is primarily supportive.

August 1st, 2008. Imaging of primary malignant tumors of peritoneal and retroperitoneal origin
However, the imaging features of these primary tumors, in combination with the clinical and demographic data, can be utilized to narrow the scope of the differential diagnosis. This chapter will present the clinical and imaging features of primary peritoneal and retroperitoneal tumors arising from the various tissue components that comprise the ligaments, mesenteries and connective tissues of these anatomic spaces.
July 24th, 2008. Primary yolk sac tumor of the omentum: a case report and review of the literature
Conclusion: To our knowledge this is the fourth case of primary omental YST. A review of the literature indicates that the diagnosis of YST requires proper evaluations of tumor makers and a skilled pathologist for analysis of frozen sections.
June 28th, 2008. Soluble Mesothelin Related Protein (SMRP) in an Asbestos Exposed Population
Conclusions: This is the first large scale prospective study of SMRP for screening for malignancy in asbestos-exposed individuals. A high false positive rate was observed. SMRP seems unlikely to prove useful in screening for MM.
June 27th, 2008. Paget disease of the humerus mimicking metastatic disease in a patient with metastatic malignant mesothelioma on whole body F-18 FDG PET/CT
The corresponding CT scan findings of cortical thickening and a "Swiss cheese" appearance were most consistent with Paget disease. The intense FDG uptake in an osseous lesion on FDG-PET in our case reminds us of the variable nature of FDG uptake in Paget disease, the possibility of false-positive findings on FDG-PET in patients with cancer, and the usefulness of the fusion techniques in the evaluation of skeletal lesions, with the potential for discriminating between benign Paget disease and other pathologic bone findings.
June 13th, 2008. Pericardial effusion due to metastatic prostate cancer: a case report
He died suddenly because of ventricular tachycardia. At autopsy, the major finding was poorly differentiated adenocarcinoma of the prostate with metastases to the mediastinum.
June 4th, 2008. An autopsy case of diffuse pleural thickening presented respiratory impairment and benign asbestos pleurisy
The autopsy disclosed asbestos-related lung diseases. We suspected that diffuse pleural thickening could be a major cause of fatal respiratory impairment in this case.

May 16th, 2008. Neoplastic and nonneoplastic conditions of serosal membrane origin: CT findings
Nonneoplastic conditions manifest as focal or diffuse thickening of the serosal membrane, a variable amount of fluid in the serosal cavity, and a soft-tissue mass at CT. Although the CT findings of some of the conditions overlap, knowledge of the typical findings is helpful in narrowing the differential diagnosis.
May 13th, 2008. Thin-walled cysts as a pathognomonic CT finding in cystic mesothelioma
Conclusion: Cystic mesothelioma can be diagnosed preoperatively by a high resolution abdominal and pelvic CT. The thin-walled cysts with great variation in size are located beneath the right hemidiaphragm, within the greater omentum and in the pelvis. No other disease with these radiologic findings has been identified.
April 30th, 2008. VATS in Diagnostic and Treatment of Malignant Pleural Mesothelioma on the Occasion of Advanced Pleural Mesothelioma
Conclusion: 1.Surgical treatment is decisive for diagnosis and treatment of malignant pleural mesothelioma even in advanced cases and have evident positive effects. 2. Surgical methods improve patient's condition, even in inoperable cases. 3. VATS surgery is modern method for diagnosis and treatment and if it necessary we can continue by conventional operation for definitive treatment of mesothelioma.
