On radiological studies, thoracic splenic lesions are visualized using CT scans. Visualized lesions can be described as solitary or multiple nodules. The locations of the lesions are mostly in the lower left pleural space and/or splenic bed. Confirmation can be done using scintigraphy with 99mTc tagged heat-damaged red blood cells. [6]
Pulmonary fibrosis is a condition in which the lungs become scarred over time. [1] Symptoms include shortness of breath, a dry cough, feeling tired, weight loss, and nail clubbing. [1] Complications may include pulmonary hypertension, respiratory failure, pneumothorax, and lung cancer. [2]
Cases in which a lung tumor invades the chest wall and an en bloc resection of ribs must be performed to achieve negative resection margins generally are felt to abrogate the value of VATS. Also pneumonectomy by VATS is a safe and feasible treatment for both benign and malignant lung diseases that induces acceptable damage and has lower ...
CT imaging provides better evaluation of the lungs, with higher sensitivity and specificity for lung cancer compared to chest radiograph (although still significant false positive rate [27]). Computed tomography (CT) that is specifically aimed at evaluating lung cancer includes the chest and the upper abdomen.
The Pancoast tumor was first described by Hare in 1838 as a "tumor involving certain nerves". [2] It was not until 1924 that the tumor was described in further detail, when Henry Pancoast, a radiologist from Philadelphia, published an article in which he reported and studied many cases of apical chest tumors that all shared the same radiographic findings and associated clinical symptoms, such ...
The background contained numerous lymphocytes and neutrophils. The shape of the tumor cell was spindle or pleomorphic, and the sizes of the tumor cells varied by more than 5-fold. The tumor cells had an abundant, thick and well-demarcated cytoplasm. The location of the nucleus was centrifugal, and the nucleus was oval or irregularly shaped.
The lung tissue lies within the same visceral pleura as the lobe in which it occurs. [1] Males and females are equally affected. [1] The arterial supply is usually derived from the lower thoracic or upper abdominal aorta. Venous drainage is usually to the left atrium via pulmonary veins establishing a left to left shunt.
The majority of cases are caused by malignant tumors within the mediastinum, most commonly lung cancer and non-Hodgkin's lymphoma, directly compressing or invading the SVC wall. Non-malignant causes are increasing in prevalence due to expanding use of intravascular devices (such as permanent central venous catheters and leads for pacemakers and ...
