Diagnosis With Brief Discussion
- Diagnosis
- Solitary fibrous tumor
- Radiologic Findings
- Chest CT shows subpleural lobulated mass abutting the LUL lingular segment. The mass shows heterogenous enhancement on postcontrast image and it has sharply delineated border. A pedicle of the mass connects the mass and fissural pleura. After CBCT(cone-beam CT)-guided PCNA, the prone CT image demonstrate a change in mass position within the thorax that confirms its pleural location.
- Brief Review
- The solitary fibrous tumor (SFT) has been described as occurring mostly in the pleura, but it has also been reported in other thoracic areas (pericardium, mediastinum), the abdomen (peritoneum, retroperitoneum, liver), and exceptionally in the nasal cavity, sinuses, nasopharynx, parapharyngeal spaces, epiglottis, thyroid, parotid, and orbit. The solitary fibrous tumor of pleura (SFTP) develops between the fifth and seventh decades of life, regardless of a previous history of smoking or asbestos exposure, and usually it is of a benign nature, with the malignant form occurring in 12% of cases. The CT scan is an important step in the preoperative work-up because it can determine the relationship of the tumor to neighboring structures and assess its resectability. CT usually reveals a sharply delineated and sometimes lobulated mass, with the same density as the musculature, which is homogeneous in most cases, especially when the lesion is small. Larger neoplasms may have a heterogeneous appearance. Contrast-enhancement is usually intense and homogeneous, as a result of the rich vascularization. However, CT also may show non-enhanced areas that are due tonecrosis, myxoid degeneration, or hemorrhage within the tumor. The angles between the tumor and the chest wall can be acute and suggest a parenchymal mass. When the tumor is close to the mediastinum or diaphragm, its relationship to the surrounding structures is sometimes difficult to assess, even using.
