“…NEUROSURGERY VOLUME 55 | NUMBER 2 | AUGUST 2004 | E435 cation resulted in low signal intensity on T2-weighted images (8,13,28). Because no calcified lesion was demonstrated within the tumor in the present case, it seems that the low signal intensity on T2-weighted images reflected abundant collagen fibers.…”

“…Most reports on the MRI appearance of SFT have noted that signal patterns on T2-weighted images depend on the main components of the tumor (8,13,27,20,22). Ferretti et al (10) compared the MRI appearance of pleural SFT with its histological findings and reported that some components, including hypocellularity and abundant collagen stroma within the tumor, corresponded to low signal intensity on T2-weighted images.…”

Solitary Fibrous Tumor of the Spinal Cord: Case Report and Review of the Literature

OBJECTIVE AND IMPORTANCE:A solitary fibrous tumor (SFT) is a rare neoplasm of probable mesenchymal origin that was first reported in the pleura but can occur in different sites. Only six cases of SFT arising from the spinal cord have been reported. CLINICAL PRESENTATION: We report a case of primary SFT occurring in the thoracic spinal cord in a 64-year-old man with Brown-Séquard syndrome. Magnetic resonance imaging revealed an intradural mass at the level of T2-T3. INTERVENTION: Total T2-T3 laminectomies were performed. The tumor appeared to be adherent to the right lateral aspect of the cord but not attached to the meninges. On histological examination, the tumor exhibited spindle cell proliferation with abundant dense collagen but without a hemangiopericytomatous pattern. Immunohistochemically, the tumor cells were reactive with CD34 and vimentin only. CONCLUSION: We report a rare case of SFT occurring in the thoracic spinal cord. Histologically and immunohistochemically, we confirmed the diagnosis of SFT. Low signal intensity on T1-and T2-weighted images corresponded to the histological findings. When a spinal cord tumor exhibits a signal pattern similar to this, SFT should be included in the differential diagnosis. Because of the rarity of reports on this condition, the clinical manifestations and course of SFT of the spinal cord are unknown, and careful long-term follow-up is recommended.

“…SFT arising from the peritoneum has been reported only occasionally. Young et al [5] reported 10 cases of peritoneal SFT, including 7 obtained from a review of the literature, and additional cases have been mentioned elsewhere [4,7,8]. In the present case, the tumor was localized in the prevesical space and attached to the parietal peritoneal surface with severe adhesion.…”

Solitary fibrous tumors (SFT) are well recognized in the pleura, but their rare occurrence at other sites has become appreciated only in recent years. We experienced a 68-year-old male patient who presented with frequency of urination and difficulty in voiding. Computed tomographic scan revealed a solid and cystic mass which measured 12 × 10 cm in the prevesical space. This tumor showed typical histopathologic features of SFT, and was immunostained positive for vimentin, CD34 and CD99. This is an extremely rare case of SFT arising from the parietal peritoneum found in the prevesical space.

“…Mixed signal intensity on T2-weighted images has also been observed in SFTs of the pleura 6 and an SFT of the presacral space. 10 The mass showed heterogeneous spoke-wheel-like enhancement after contrast administration. Although this pattern of enhancement was originally described on angiography in renal oncocytomas, it is not specific and can be seen in renal cell carcinomas as well.…”

The magnetic resonance imaging findings in a patient with a large solitary fibrous tumor (SFT) of the kidney originating in the renal capsule are presented. SFT of the kidney is a rare, usually benign tumor with indolent clinical behavior. MRI revealed a diffusely hypointense mass on T2-weighted images without central necrosis despite the large size of the lesion. These imaging features, atypical for renal cell carcinoma, can suggest the diagnosis of SFT and may be an indication for attempting nephron-sparing surgery.
