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]
There is still much debate to whether pulmonary sequestration is a congenital problem or acquired through recurrent pulmonary infection. It is widely believed that extralobar pulmonary sequestrations are a result of prenatal pulmonary malformation while intralobar pulmonary sequestrations can develop due to recurrent pulmonary infections in adolescents and young adults.
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]
These are common presenting symptoms of chronic and cardiogenic pulmonary edema due to left ventricular failure. The development of pulmonary edema may be associated with symptoms and signs of "fluid overload" in the lungs; this is a non-specific term to describe the manifestations of right ventricular failure on the rest of the body.
IBS symptoms can vary greatly from person to person, and range from mild to extreme. Generally, IBS involves abdominal pain plus altered bowel movements, Dr. Lee says. The pain and bowel movements ...
