“…The TICs of sinonasal SFTs may be related to the hemangiopericytoma-like areas identified histopathologically and to a hypervascular arterial phase blush present on angiography. 23 This technique may give an important clue to diagnose a suspected SFT in the sinonasal cavity.…”

SUMMARY: SFT is a rare lesion of the sinonasal cavity. We retrospectively reviewed 5 patients with histopathologically proved sinonasal SFTs to determine their CT and MR imaging features. All patients underwent paranasal sinus CT and MR imaging. Four SFTs occurred in the nasal cavity, and 1, in the maxillary sinus. All SFTs had well-defined margins, and the mean maximum diameter was 55 mm. On nonenhanced CT, 5 SFTs appeared homogeneously isoattenuating to gray matter. The most common manifestations of bony involvement were bony remodeling and thinning. On MR imaging, 5 SFTs were isointense to gray matter on T1-weighted images, and the lesions were isointense in 3 and hypointense in 2 patients on T2-weighted images. The lesions showed heterogeneously marked enhancement on postenhanced MR images. Four patients underwent dynamic contrast-enhanced MR imaging, and the TICs showed a washout pattern. A familiarity with the imaging findings of sinonasal SFT may help to diagnose this entity.

“…In the T1 sequences, they are isointense to gray matter with moderate homogeneous or heterogeneous gadolinium enhancement, while on T2 they are hypointense. SFTs frequently show centrally located, strongly hypodense foci in T1 as well as in T2, representing collagenrich areas [7,20]. Other collagen-containing tumors such as fibromatosis, sclerotic pseudotumors or scirrhous carcinoma metastases show a similar T1 and T2 pattern.…”

Solitary fibrous tumors of the orbit (SFT) are mesenchymal lesions that can develop either as malignant or benign neoplasias. We describe the histological features leading to the diagnosis in two females and review the current literature. Diagnosis of SFT only can be performed by histological examination, since clinical signs and radiological features are not specific enough. Even a malignant or benign course cannot be predicted, since clinical and radiological features do not correlate with histological signs of malignancy and vice versa. Radical resection is the treatment of choice, since no other treatment option has been proven to be efficient.
