First described by Klemperer and Rabin in 1931, solitary fibrous tumour of the pleura
(SFTP) is a mesenchymal tumor that tends to involve the pleura, although it has also
been described in other thoracic areas (mediastinum, pericardium and pulmonary parenchyma)
and in extrathoracic sites (meninges, epiglottis, salivary glands, thyroid, kidneys
and breast). SFTP usually presents as a peripheral mass abutting the pleural surface,
to which it is attached by a broad base or, more frequently, by a pedicle that allows
it to be mobile within the pleural cavity. A precise preoperative diagnosis can be
arrived at with a cutting-needle biopsy, although most cases are diagnosed with postoperative
histology and immunohistochemical analysis of the dissected sample. SFTP, owing to
its large size or unusual locations (paraspinal, paramediastinal, intrafissural and
intraparenchymal), can pose interpretation problems or, indeed, point towards a diagnosis
of diseases of a totally different nature. We present some unusual radiographic and
computed tomography (CT) images of large SFTP or SFTP located in atypical thoracic
locations in patients who underwent surgical resection.
