Learning objectives
To discuss the clinical presentation of patients with Localized Fibrous Tumors of Pleura (LFTP).
To define the radiographic charactheristics of LFTP.
We report 19 cases between the years 2000 and 2010 with LFTP treated in our hospital.We review the literature in order to define the radiologic characteristics of these tumors,
diagnosis,
prognosis and treatment options.
Background
Primary tumors of the pleura can be categorized as diffuse or localized:
Diffuse malignant mesothelioma is more common,
is related to asbestos exposure,
and is associated with a poor prognosis.
Localized mesothelioma is called localized fibrous tumor of pleura (LFTP); this tumor is an uncommon neoplasm (accounting for less than 5% of all pleural tumors),
has a controversial histogenesis and is unrelated to asbestos exposure.
LFTPs exist in benign and malignant forms
Nowadays,
the origin is recognized widely as mesenchymal cells of submesothelial tissues of...
Imaging findings OR Procedure details
GENERAL IMAGING FINDINGS:
The diagnosis of LFTP is important because the tumor is potentially resectable for cure despite its typically large size.
Normally,
LFTPis discovered incidentally on chest radiographs.
Findings from computed tomography (CT) scanning and magnetic resonance imaging (MRI) can suggest the diagnosis of LFTP.
However,
histopathologic examination is needed for a definitive diagnosis.
CHEST RADIOGRAPHY:
In most patients,
an LFTP is detected as an incidental finding on a chest radiograph,
appearing as a well-circumscribed,
homogeneous soft-tissue mass that is related closely to the...
Conclusion
Chest radiographic findings are nonspecific,
and the lesion can sometimes be obscured by associated pleural effusion.
CT and MRI scans may show characteristic findings that are suggestive of LFTP but that are not always pathognomonic.
However,
histopathologic examination is needed for a definitive diagnosis.
The pleural origin of large lesions can be difficult to detect,
especially on chest radiographs and even on CT and MRI scans.
Complete resection remains the mainstay of cure for SFTP.
We recommend preoperative angiography and embolization for giant SFTP which...
