She presented left sided abdominal pain, decreased appetite, and history diarrhoea 15 days. developed absolute constipation during her preoperative investigations, in CT scan revealed ileoileal intussusc...

INTRODUCTION The clinical profile as well as the therapeutic and diagnostic strategies for patients with pulmonary embolism, describes clinical practice in the approach of the disease. Such information, scarce in national studies, enables a better understanding of pulmonary embolism. METHODS A multicenter trial included 727 patients with pulmonary embolism who were admitted in emergency or in...

Melanoma is a cutaneous malignant neoplasm of melanocytes. Primary malignant melanoma (MM) of the lung is very rare. Although previous reports have described the radiologic features of pulmonary MM, its rarity means that many factors are unknown. Thus, radiologic diagnosis is very difficult. Furthermore, there is little information regarding diagnostic application and/or the usefulness of [(18)...

BACKGROUND The objective of this study was to evaluate the imaging characteristics of pulmonary artery sarcoma (PAS) on pulmonary artery computed tomography angiography (PACTA) that can be used to differentiate between PAS and pulmonary thromboembolic diseases, including chronic thromboembolic pulmonary hypertension (CTEPH) and acute pulmonary embolism (APE). METHODS The clinical data and ima...

In vivo animal studies support the concept that monocytes and macrophages are important in the immune surveillance of oncogenesis and in vitro activated murine macrophages are cytocidal for tumor cells. In this study. we examined human pulmonary macrophage and blood monocyte tumor cell cytotoxicity (a measure of cytostasis and cell kill) and cytocidal activity (cell kill). Three human tumor cel...

Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant neoplasm, but, generally, asymptomatic with r...
