Inflammatory Pulmonary Pseudotumor, also known as inflammatory myofibroblastic tumor or plasma cell granuloma, is a rare benign lung condition that is characterized by the presence of a mass-like lesion in the lung tissue. This condition typically affects children and young adults, although it can occur at any age.
The term "inflammatory" refers to the inflammatory response that occurs within the lung tissue, characterized by the accumulation of immune cells, such as lymphocytes and plasma cells. This inflammatory reaction can cause the formation of a tumor-like mass, which is why it is called a pseudotumor.
The etiology of Inflammatory Pulmonary Pseudotumor is not fully understood, but it is believed to be associated with an abnormal immune response or an autoimmune reaction. The exact triggers of this condition remain unclear.
Symptoms of Inflammatory Pulmonary Pseudotumor can include cough, chest pain, fever, and difficulty breathing. However, some individuals may remain asymptomatic until the mass grows larger or puts pressure on surrounding structures.
Diagnosis of Inflammatory Pulmonary Pseudotumor involves imaging studies, such as chest X-ray, computed tomography (CT) scan, or magnetic resonance imaging (MRI). A biopsy may also be performed to confirm the diagnosis and rule out malignancy.
Treatment options for Inflammatory Pulmonary Pseudotumor typically involve surgical removal of the mass. In some cases, if the tumor is not causing symptoms or is in a difficult-to-reach location, a watchful waiting approach may be adopted. Corticosteroids or other immunosuppressive medications may be prescribed in cases where the mass is not amenable to surgical removal or recurs after surgery.
In general, the prognosis for Inflammatory Pulmonary Pseudotumor is good,
