Juxtaphrenic peak sign is a radiographic sign seen in lobar collapse or after lobectomy of the lung. [1] [2] This sign was first described by Katten and colleagues in 1980, and therefore, it is also called Katten's sign. [3] The juxtaphrenic peak is most commonly caused due to the traction from the inferior accessory fissure.
On radiological studies, a pleural pseudotumor is visualized as a biconcave or lenticular lesion using conventional chest x-rays and CT scans. The lesion is most commonly located in the minor (horizontal) fissure of the lung. A pleural pseudotumor is also associated with the presence of dependent pleural effusions. [9]
An accessory fissure was also found in 14% and 22% of left and right lungs, respectively. [47] An oblique fissure was found to be incomplete in 21% to 47% of left lungs. [48] In some cases a fissure is absent, or extra, resulting in a right lung with only two lobes, or a left lung with three lobes. [46]
It’s important to pay attention to the signs of lung disease and any symptoms that indicate your lungs might not be healthy, as early detection can go a long way in helping to manage and treat ...
Signs and symptoms of white lung pneumonia can vary based on what caused the illness in the first place, Dr. Ganjian says. However, these are the most common pneumonia symptoms, according to the ...
In the absence of a pulmonary artery, the lung on the affected side is not involved in ventilation. Instead, it leads to symptoms such as hemoptysis, pulmonary hypertension and congestive heart failure. [11] Removal of the affected lung may treat related complications. Successful neonatal pneumonectomy has been reported in a 23-day-old baby. [4]
Two thirds of the time, the sequestration is located in the paravertebral gutter in the posterior segment of the left lower lobe. Unlike extralobar sequestration, it is rarely associated with other developmental abnormalities. Patients present with signs and symptoms of pulmonary infection of a lower lobe mass.
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
