“…In such cases, analysis of the thymic cavity is also fundamental. In fact, in lesions of pleural origin, the thymic cavity is compressed and dislocated, contrary to what occurs in the presence of a mediastinal mass (which expands, compressing the pulmonary parenchyma without causing mediastinal shift) [43]. With the advent of modern equipment and the use of multiplanar imaging that enables detailed study of the mediastinum, it has become easier to distinguish between masses of thymic origin and lesions of the mediastinal pleura, even though it should be recalled that SFTP may also arise in the mediastinum [4].…”

“…In questi casi, se localizzati a livello del mediastino superiore l'analisi della loggia timica risulta fondamentale. Infatti, in caso di lesioni a partenza pleurica essa apparirà compressa e dislocata controlateralmente rispetto a quanto avviene in presenza di masse mediastiniche che si espandono al suo interno mantenendo il mediastino in asse [43]. Grazie all'avvento delle apparecchiature di ultima generazione e all'utilizzo di immagini multiplanari, che permettono uno studio dettagliato del mediastino, risulta più facile distinguere fra una massa di origine timica e una lesione a partenza dalla pleura mediastinica, pur se bisogna ricordarsi che anche il tumore fibroso solitario della pleura può localizzarsi primitivamente nel mediastino [4].…”

First described by Klemperer and Rabin in 1931, solitary fibrous tumour of the pleura (SFTP) is a mesenchymal tumour 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, para-mediastinal, intra-fissural 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.

“…Eroglu et al [14] reported a case of primary leiomyosarcoma of the anterior mediastinum presenting as a large (11-cm) mass without involvement of the main vessels or oesophagus, well-circumscribed, heterogeneous enhancement, associated pleural effusion but no lymphadenopathy. Cardinale et al [15] described the CT features of 26 SFTs of the pleura with benign and malignant behaviour. The authors showed that up to 50 % of the lesions were larger than 10 cm, and even the largest lesions presented well–defined margins and lobulated contours, also with heterogeneous enhancement and important areas of necrosis, and 24 % of the lesions presented identifiable intralesional vessels.…”

“…The intratumoural enhanced vessels are usually tortuous and dilated, and probably represent tumoural pathological feeding vessels. To our knowledge, this feature has not been described as characteristic for other mediastinal or pleuropulmonary tumours than SFTs [15, 17, 18]. …”

Primary intrathoracic malignant mesenchymal tumours: computed tomography features of a rare group of chest neoplasms

et al. 2014

ObjectivesTo describe the computed tomography (CT) features in a case series of primary intrathoracic extracardiac malignant mesenchymal tumours (sarcomas).MethodsA 5-year retrospective research was conducted, and 18 patients were selected. CT exams were reviewed by two chest radiologists, blinded to tumour pathological type, origin and grade. Lesions were described in relation to location, size, shape, margins, enhancement, presence of cavitation, calcifications, ground glass component, intratumoural enhanced vessels, pleural effusion, pleural tags, lymphangitis, chest wall/rib involvement and pathological lymph nodes.ResultsThe readers described five pulmonary, six mediastinal and seven pleural/wall based lesions. Mean largest diameter was 103 mm. The most frequent shape was irregular (n = 12), most predominant margin was smooth (n = 12) and enhancement was mostly heterogeneous (n = 8). Intratumoural vessels and pleural effusion were seen in 11 patients. Pathological lymph nodes were present in four cases and calcifications in two cases.ConclusionsSome frequent radiological features were described independently of tumour location and subtype. A sarcoma should be included as a major differential diagnosis when the radiologist faces an intrathoracic mass of large size (>70 mm) but with well defined smooth or lobulated margins, especially if presenting intratumoural vessels, associated pleural effusion but no significant lymphadenopathy.Main messages• Malignant mesenchymal tumours (sarcomas) are rare and can arise from any structure in the chest.• Intrathoracic sarcomas show some frequent radiological features, independent of location and type.• Some CT features may help the radiologist suspect for a sarcoma instead of other more common tumours.

Imaging of benign solitary fibrous tumor of the pleura: a pictorial essay

et al. 2010

View full text Add to dashboard Cite

Solitary fibrous tumor of the pleura (SFTP) is a mesenchymal tumor that tends to involve the pleura, and is also described in other thoracic and extrathoracic sites. SFTP usually presents as a peripheral mass abutting the pleural surface, to which it is attached by a broad base or by a pedicle that allows it to be mobile. SFTPs exist in benign and malignant forms. A precise pre-operative diagnosis can be arrived at with a cutting-needle biopsy, although most cases are diagnosed with postoperative histology and immunohistochemical analysis. In this pictorial essay, we review a large series of cases, with emphasis on the radiographic appearance of these lesions and their findings from computed tomography, magnetic resonance imaging, ultrasonography and positron emission tomography.
