Ar tumors [1]. Hemangiopericytoma was first reported by stout and murray [2] in 1942, and it generally occurs in the soft tissue of the thigh, pelvis, and retroperitoneum, but rarely in the lung, pleura, or chest wall [3]. viagra no prescription We describe herein a case of pleural pedunculate hemangiopericytoma that was resected under video-assisted thoracoscopic surgery. A 40-year-old woman was referred to our institution with an abnormal shadow in the lower lobe of the right lung, which had been first noted on a routine chest roentgenogram on may 2001. best online viagra She had no symptoms related to the mass and had no history of smoking or serious illness. viagra o viagra o viagra forum Physical examination was essentially within normal limits, and laboratory studies revealed chronic hypochromic anemia, a hemoglobin of 7. buy viagra online 9 g/dl, and a hematocrit of 27. viagra without prescription 8%. order viagra online The tumor markers alpha-fetoprotein, sialyl lewis x-1, carcinoembryonic antigen, neuron-specific enolase, and squamous cell carcinoma antigen were within normal limits. A computed tomographic scan of the chest revealed a large solid tumorous mass measuring 12 x 7 x 3 cm located in the right costodiaphragmatic recess, and it showed a lack of homogeneity with the main peripheral enhancement (fig 1a). The shadow of the mass moved with changes in the patient's position, indicating that this was a pedunculated tumor (fig 1b). Magnetic resonance scanning showed that the tumor appeared inhomogeneous, with hypo-intense and hyper-intense signals on t1-weighed images and an inhomogeneous pattern with predominant hyper-intensity on t2-weighed images with a smooth outline. erectile dysfunction viagra reviews Abdominal computed tomography, gallium-67 scintigraphy, thallium-201 scintigraphy, and head computed tomography were also performed, but no abnormalities were found. cheap viagra online A transluminal computed tomographic-guided fine needle aspiration biopsy indicated a probable mesenchymal neoplasm. viagra side effects in women At preoperative staging, no metastatic lesions were found and a surgical approach was suggested.
