Lung inflammatory pseudotumor, also known as inflammatory myofibroblastic tumor (IMT) of the lung, is a rare non-cancerous condition characterized by the development of a mass or tumor-like growth in the lung. It primarily affects the connective tissue and can occur at any age, but is most commonly observed in children and young adults.
This inflammatory pseudotumor is believed to arise from an abnormal immune response to an unidentified trigger, resulting in an excessive proliferation of inflammatory cells and fibrous tissue in the lung. The exact cause of this condition is still unknown and requires further investigation.
Typically, patients with lung inflammatory pseudotumor may experience symptoms such as cough, chest pain, shortness of breath, and fever. These symptoms can vary depending on the size and location of the tumor within the lung.
Diagnosis of lung inflammatory pseudotumor involves a variety of imaging techniques, including chest X-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI). Additionally, a tissue biopsy or surgical removal of the tumor may be required to confirm the diagnosis and exclude the possibility of other lung malignancies.
Treatment of lung inflammatory pseudotumor often involves surgical resection of the tumor, as this condition is deemed benign. In cases where complete surgical removal is not possible, other treatment options such as corticosteroids or non-steroidal anti-inflammatory medications may be utilized to help reduce inflammation and tumor growth.
While lung inflammatory pseudotumor is generally considered a benign condition, long-term monitoring is recommended, as there have been rare instances of recurrence or progression to malignant forms.
