1/23. Primary posterior chest wall echinococcosis.Hydatid cyst is not mentioned among the chest wall tumours in areas not known to harbour echinococcosis. One of the uncommon sites for echinococcosis even in endemic countries is the chest wall. The striking resemblance between neoplasm and hydatid cysts forms a diagnostic dilemma and makes the correct diagnosis essential before surgery.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/23. Thoracic lymphadenopathy in hiv patients: spectrum of disease and differential diagnosis.To evaluate the etiology and differential features of intrathoracic lymphadenopathy (LAD) in hiv patients, chest computed tomography (CT) records from an 18-month period were reviewed to identify all hiv-positive patients with intrathoracic LAD (nodal size > or = 1 cm). medical records were reviewed for the documentation of specific diseases causing LAD and the CD4 count at the time of imaging. Of 45 hiv-positive patients with LAD, 40 had specific diagnoses including 22 (55%) infections and 17 (43%) tumors; one patient had both (3%). Mycobacterial disease accounted for 78% of infections; five cases were secondary to bacterial pneumonia and sepsis. Of tumors, lymphoma (7 cases, 39%) was most common, followed by lung cancer, germ cell tumors, and Kaposi's sarcoma. Mean CD4 cell count in patients with tumors was much higher than in patients with infections (314 vs. 62, p < .01). patients with tumors were somewhat more likely than patients with infections to demonstrate axillary adenopathy (29 vs. 5%, p = .068). Cavitary disease was only observed in patients with infections (27%, p < .03). CT and clinical findings may help direct the differential diagnosis of LAD in AIDS, and promote expedient definitive diagnosis and therapy.- - - - - - - - - - ranking = 4.5148799395715keywords = cancer (Clic here for more details about this article) |
3/23. Thoracolithiasis.Thoracolithiasis without any history of chest traumas or interventions is pathologically rare, with only 9 cases including our 2, reported thus far in the literature. Case 1: A 76-year-old man admitted to our hospital had an abnormal shadow in chest radiography that gradually enlarged. serum carcinoembrionic antigen was slightly elevated during follow-up. A milky white tumor 1.5 cm in diameter with many projections was found in the thoracic cavity and removed by thoracoscopy. Histopathological examination showed the tumor to consist of fibrous tissue with fatty necrosis at the core. Case 2: A 54-year-old woman admitted to our hospital had an abnormal shadow in chest screening radiography in 1998. Transbronchial biopsy showed this shadow to be lung adenocarcinoma. A small trigonal pyramid-shaped milky white nodule 5 mm in diameter was found in the thorax during lobectomy for lung cancer. Histopathological examination showed this nodule also to consist of fibrous tissue with fatty necrosis.- - - - - - - - - - ranking = 4.5148799395715keywords = cancer (Clic here for more details about this article) |
4/23. myositis ossificans of the chest wall simulating malignant neoplasm.myositis ossificans originating from the chest wall is extremely rare. We report a case of myositis ossificans occurring in a young woman with progressive painful swelling in the chest wall. Preoperative examination suggested a malignant neoplasm originating from soft tissue. Although rare, myositis ossificans is one of the potential causes of painful swelling in the chest wall, and can be mistaken for a malignant neoplasm.- - - - - - - - - - ranking = 6keywords = neoplasm (Clic here for more details about this article) |
5/23. Thoracic ectopic kidney in a child: a case report.Congenital thoracic ectopic kidney is a very rare developmental anomaly and the rarest form of all ectopic kidneys. It is usually asymptomatic and discovered incidentally on a routine chest radiography. We report a thoracic ectopic kidney in a 19-month-old boy, which initially presented as a well demarcated mass at the base of the right lung on chest x-ray. Intravenous pyelography (IVP) and thoraco-abdominal computed tomography (CT) demonstrated a normal functioning transdiaphragmatic thoracic ectopic right kidney, but technetium-99m DTPA and DMSA scintigraphy demonstrated pelvic stasis. We hereby discuss the features of congenital thoracic ectopic kidney and review the literature. Although it is extremely rare, thoracic ectopic kidney should be considered in differential diagnosis of a mass with a well demarcated superior margin in the lower part of the thorax, and renal scintigraphy must be performed even if CT and IVP results are normal.- - - - - - - - - - ranking = 2078.9083017345keywords = kidney (Clic here for more details about this article) |
6/23. Intrathoracic kidney in an adult.An intrathoracic kidney, although rare, should be considered in a patient with a mass at the base of the lung on a chest radiograph. Excretory urography is diagnostic and may eliminate the need for further extensive investigation and operation.- - - - - - - - - - ranking = 1039.4541508672keywords = kidney (Clic here for more details about this article) |
7/23. prenatal diagnosis of an ectopic intrathoracic kidney in right-sided congenital diaphragmatic hernia using color Doppler ultrasonography.The prenatal sonographic features of a fetus with right-sided congenital diaphragmatic hernia diagnosed at 33 weeks are presented. color Doppler demonstrated an abnormal course of the right renal artery, arising from the aorta and feeding the intrathoracic right kidney. This case report stresses the role of color Doppler in defining which organs have herniated in fetuses with diaphragmatic hernia.- - - - - - - - - - ranking = 1039.4541508672keywords = kidney (Clic here for more details about this article) |
8/23. Ureteropelvic junction obstruction in a thoracic kidney treated by dismembered pyeloplasty.Ectopic positioning of the kidney is a relatively common event, with the thoracic location of the ectopic kidney the most unusual. At least 140 cases of thoracic kidney have been described, with no consistent anomalies reported in association with the superior location. The vast majority of patients with thoracic kidney are asymptomatic, with the problem discovered incidentally. We report the first documented case of a thoracic kidney presenting with flank pain and demonstrating ureteropelvic junction obstruction on nuclear scintigraphy treated by open dismembered pyeloplasty through a supra-11th rib incision.- - - - - - - - - - ranking = 1871.017471561keywords = kidney (Clic here for more details about this article) |
9/23. Multiple thoracic paraspinal meningeal cysts in autosomal dominant polycystic kidney disease.Spinal meningeal cysts have been reported in 3 patients as an extrarenal manifestation of autosomal dominant polycystic kidney disease (ADPKD). The authors report on a fourth patient with ADPKD who was found to harbor 7 thoracic meningeal cysts, appearing as paraspinal masses on plain films. The authors provide a comprehensive radiologic description of this abnormality.- - - - - - - - - - ranking = 1039.4541508672keywords = kidney (Clic here for more details about this article) |
10/23. Percutaneous nephrolithotomy of an intrathoracic kidney.We present a 35-year-old woman with symptomatic urolithiasis in an intrathoracic kidney. Percutaneous nephrolithotomy was successfully performed after ureteroscopy failed because of the unusual length of the ureter associated with the kidney position. We report the first case of percutaneous nephrolithotomy of an intrathoracic kidney.- - - - - - - - - - ranking = 1455.2358112141keywords = kidney (Clic here for more details about this article) |
