[Localized fibrous tumor of the pleura: radiological findings]

Localized fibrous tumors of the pleura are rare tumors that represent less than 5% of the pleural tumors, although they have also been described in extrathoracic locations such as the abdomen, head and neck or central nervous system. A total of 80% begin in the visceral pleura and are not related with environmental risk factors. They generally occur in patients over 50 with a mild predominance in the woman. Up to 50% of the patients are asymptomatic, so that it appears as an incidental finding on the chest X-ray. These are slow growing tumors. They are seen on the X-ray as well-defined rounded lesions dependent on the pleura and 50% are pediculated. It is important to know its radiological characteristics for its diagnosis of suspicion and correct treatment since surgical resection is generally curative. Local recurrence after the surgery is very common if it is not completely excised.
