mesentery. Signs and symptoms vary depending on the site of the tumor. Some people with an IMT are asymptomatic, while others may have nonspecific respiratory symptoms, fever, or pain. IMTs may recur, and occasionally become locally invasive and/or spread (metastasize) to other parts of the body. The underlying cause of IMTs is poorly understood. Some cases have been linked to translocations involving the ALK gene. Treatment involves surgical removal when possible, although there are reports of treatment with oral steroids and radiation therapy.An inflammatory myofibroblastic tumor (IMT) is an uncommon, presumably benign (non-cancerous) tumor made up of cells called myofibroblastic spindle cells. It usually develops in children or young adults, but can affect people of any age. An IMT can occur in almost any part of the body but is most commonly found in the lung, orbit (eye socket), peritoneum (lining of the abdominal cavity and internal organs), and
