Inflammatory pseudotumors can be multiple. It often occurs in the eye or the lungs, and ocular lesions can often involve neighboring sites; lung lesions are often solitary, but multiple foci in both lungs can be found. Inflammatory pseudotumor is a kind of idiopathic chronic non-specific value-added inflammation, the essence of which is inflammation, but the clinical manifestation is like a tumor, so it is called inflammatory pseudotumor. This disease is relatively common in clinical practice, the etiology of which is not known, and is currently thought to be an immune-responsive disease. It can occur at any age and is more common in men over the age of 40. It often occurs in the eyes and lungs. If inflammatory pseudotumor occurs in the eye, it can develop in one eye or both eyes at the same time, and often involves the extraocular muscles, the fovea of the eye or the lacrimal gland, and a small number of patients can be accompanied by lesions of the same nature in other parts of the body. Common clinical manifestations include eye pain, diplopia, swelling and bleeding of the eyelids and the conjunctiva, protrusion of the eyeballs, limitation of movement, and loss of vision, etc. The lungs are more common with inflammatory pseudotumor. Inflammatory pseudotumor in the lungs is less common than that in the eyes, and usually does not grow rapidly, and can occur singly or in multiple cases. They often present with cough, sputum, hemoptysis, chest pain and low-grade fever. Patients may undergo surgical resection and postoperative pathologic examination, and further management will be based on the results of the pathologic examination. If you have any suspected symptoms, please go to the hospital promptly.
