Lung inflammatory pseudotumors, also known as inflammatory myofibroblastic tumors, are rare noncancerous growths that can develop in the lungs. They are characterized by the formation of masses or nodules composed of inflamed and abnormal connective tissue.
Inflammatory pseudotumors predominantly affect children and young adults but can occur in individuals of any age. The exact cause of these tumors is still unclear, but they are believed to result from an abnormal immune response or an excessive inflammatory reaction to an unknown trigger. They can also be associated with infections or genetic alterations.
The symptoms of lung inflammatory pseudotumors vary depending on the size and location of the tumor. They may include persistent cough, chest pain, shortness of breath, fever, weight loss, and fatigue. However, some cases may remain asymptomatic and are incidentally detected during routine imaging exams.
Diagnosing lung inflammatory pseudotumors often requires a combination of imaging tests, such as chest X-rays, CT scans, and MRI scans, along with a biopsy to examine the abnormal tissue. Treatment options for these tumors depend on several factors, including the size, location, and symptoms. In some cases, no treatment is necessary as the tumors may shrink or disappear on their own. However, surgical removal or minimally invasive procedures may be recommended to alleviate symptoms or ensure complete tumor removal. In rare cases where the tumors cause significant issues or recur, chemotherapy or radiation therapy may be considered.
Overall, lung inflammatory pseudotumors are uncommon benign growths in the lungs that can cause a range of symptoms and typically require medical intervention for management.
