These are solitary lesions lying within the lung varying in size between 10 and 80 millimeters in diameter. [citation needed] There are four elements in this tumour: solid, papillary, sclerotic and hemangiomatous. These are present in variable proportions depending on the lesion. Calcification occurs in 40%.
The most common benign coin lesion is a granuloma (inflammatory nodule), for example due to tuberculosis or a fungal infection, such as Coccidioidomycosis. [6] Other infectious causes include a lung abscess , pneumonia (including pneumocystis pneumonia ) or rarely nocardial infection or worm infection (such as dirofilariasis or dog heartworm ...
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]
Parenchymal hamartoma of the lung. The surrounding lung falls away from the well-circumscribed mass, a typical feature of these lesions. The hamartoma shows a variegated yellow and white appearance, which corresponds respectively to fat and cartilage. About 5–8% of all solitary lung nodules and about 75% of all benign lung tumors, are ...
Examples of this use of the term granuloma are the lesions known as vocal cord granuloma (known as contact granuloma), pyogenic granuloma, and intubation granuloma, all of which are examples of granulation tissue, not granulomas. "Pulmonary hyalinizing granuloma" is a lesion characterized by keloid-like fibrosis in the lung and is not ...
However, a benign tumour is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumours usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For ...
Small, scattered lesions may be asymptomatic. Intracranial tuberculomas in children are often infratentorial, occurring near the cerebellum and base of the brain. In this population, symptoms such as headache, fever, focal neurologic findings and seizures have been seen [3] in addition to papilledema with or without meningitis. [20]
