“…5,9,10,12,13 It is our opinion that, compared with enhanced T1-and T2-weighted images, unenhanced T1-weighted images have less value in the differential diagnosis of schwannoma. Some of the features of schwannoma, including a well-circumscribed round or ovoid shape, iso-or hypointensity on T1-weighted imaging, solitary fibrous tumours, 16 isolated neurofibromas, 17 cavernous hemangiomas, 18 and meningiomas, are shared by a number of other orbital lesions. 19 It is difficult to distinguish these lesions from those of schwannoma on T1-weighted images.…”

Purpose To evaluate the diagnostic value of magnetic resonance imaging (MRI) and illustrate the common MRI features of orbital schwannoma. Methods We reviewed 62 consecutive cases of pathologically proven orbital schwannoma investigated by MRI. All cases were examined using T1-and T2-weighted images. Enhanced T1-weighted images were obtained after administration of gadopentetate dimeglumine. The images were analysed and compared. Results Cone-shaped lesions were the most frequent (16, 26%), followed by dumbbell-shaped (10, 16%), oval (9, 15%) and round lesions (8, 13%). The most common site was the superior aspect of the orbit (17, 27%), followed by the medial superior (12, 19%) and the orbital apex (12, 19%). On unenhanced T1-weighted images, 53 (85%) lesions showed isointensity or small patches of hypointensity. The patterns of enhancement seen on T1-weighted images correlated with the signal characteristics of unenhanced T2-weighted images. Five patterns emerged in our series. Among these patterns, the most common sign, found in 18 (29%) cases, was peripheral (ring) enhancement on enhanced T1-weighted images, which showed peripheral isointensity with central hyperintensity on T2-weighted images. Lesions with homogeneous or heterogeneous enhancement were seen in 16 (26%) and 26 (42%) cases, respectively. Conclusions MRI is a valuable diagnostic method for orbital schwannoma, particularly when contrast is applied. The locations and shapes of tumours can be seen distinctly. T1-weighted images are relatively nonspecific. T2-weighted and enhanced T1-weighted images provide information about the pathology of tumours. In particular, peripheral enhancement should be considered a target sign of schwannoma.

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.

“…(1) These pleurally based neoplasms are predominantly benign with malignant pathology and behaviour described in 10% to 36% of cases. (2,3,4,5) More recently SFT have been described in a wide variety of extra-thoracic locations including the head and neck, (6,7,8,9,10) abdominal and retroperitoneal sites (9,11,12,13,14) and soft tissues. (9,15,16) Most of these early series of ESFT reported primary pathological data but gave little analysis of the correlation between pathological findings and clinical course, they predominantly represent descriptive pathological series with short clinical follow-up.…”

Background: Extra-thoracic solitary fibrous tumours (ESFT) have traditionally been regarded as indolent neoplasms similar to their intra-thoracic counterparts. However there has been some evidence that a subset of more aggressively malignant tumours exist. We examined our experience with these rare tumours in an effort to clarify their clinicopathological behaviour and relate this to their histopathological findings.
