Inflammatory pseudotumor of the lung, also known as inflammatory myofibroblastic tumor, is a rare benign (non-cancerous) condition that affects the lung tissue. It is characterized by the formation of a mass or tumor composed of a mixture of inflammatory cells, fibroblasts (cells that produce connective tissue), and myofibroblasts (cells with features of both fibroblasts and smooth muscle cells). This condition can occur at any age, but it is more commonly found in children and young adults.
The exact cause of inflammatory pseudotumor of the lung is still unclear. However, it has been suggested that it may be the result of an abnormal response of the immune system to infection or inflammation in the lung. It is not associated with smoking or exposure to environmental toxins.
Symptoms of inflammatory pseudotumor of the lung can vary depending on the size and location of the tumor. Some patients may experience cough, shortness of breath, chest pain, fever, and weight loss. In some cases, the condition may be discovered incidentally during routine chest imaging.
Diagnosis of inflammatory pseudotumor of the lung involves a combination of imaging studies, such as chest X-ray, computed tomography (CT) scan, and magnetic resonance imaging (MRI), as well as a biopsy to confirm the presence of inflammatory cells and rule out other conditions.
Treatment options for inflammatory pseudotumor of the lung include surgical resection (removal of the tumor) or corticosteroid medications to reduce inflammation and shrink the mass. In most cases, the prognosis for patients with this condition is favorable, as it is a benign condition that typically does not spread or recur after treatment. However, long-term follow-up is recommended to monitor for any potential recurrence or
