Diagnosis With Brief Discussion
- Diagnosis
- Solitary fibrous tumor of pleura
- Radiologic Findings
- Chest radiography shows round mass-like opacity in right lower lung field (Fig. 1). Transverse image of pre-contrast CT (Fig. 2) shows a well-defined nodule (2 cm in size) involving both pleura and intercostal space of right hemithorax. Post-contrast CT image (Fig. 3) shows heterogeneous and strong contrast enhancement in the right chest wall nodule. Furthermore, the chest wall nodule also shows hypermetabolism on FDG-PET image (Fig. 4).
- Brief Review
- Fibrous tumors most commonly occur in the pleura but have also been described in the pericardium, mediastinum, lung, peritoneum, chest wall, orbits, and other sites. About 12% of solitary fibrous tumors are malignant and eventually lead to death through local recurrence or metastatic disease. The tumors are usually well circumscribed. They range in size from 1 to 36 cm, with a mean of 6 cm. Approximately 50% have a pedicle attached to the pleura, 1 cm in length, that contains hypertrophic arteries and veins. As tumors enlarge, they appear more heterogeneous; areas of necrosis, hemorrhage, and cystic changes are typically identified within the lesions. benign solitary fibrous tumors demonstrated low-grade FDG uptake, and malignant solitary fibrous tumors demonstrated somewhat greater FDG uptake based on standardized uptake values. Complete surgical resection is the treatment of choice.
