“…Within the thorax, SFT is hypoechoic and despite being a vascular soft tissue lesion, rarely demonstrates flow on Doppler imaging. 10 This case was unusual, as it demonstrated internal vascularity.…”

“…The use of computed tomography is reported in the literature, 10 but in this case, MRI was performed and demonstrated heterogeneous enhancement on post contrast T1-weighted MRI. A heterogeneous, high signal pattern following intravenous contrast may be observed in a range of pathologies, but in this case, based on the clinical and radiological findings, it was reported as being due to the presence of multiple flow voids, consistent with a vascular anomaly.…”

“…7 SFT radiographic findings are variable and non-specific. 9,10 The use of US in the initial assessment of these lesions has not been documented in the head and neck region. US is a quick, non-invasive imaging modality that is very useful in the initial assessment of superficial masses within the head and neck and can potentially differentiate between cystic and solid, benign and malignant, and allows assessment of vascularity, as well as guiding biopsy.…”

“…In this patient, there was no evidence of bone remodelling or destruction, features of SFT that have been previously reported. 10 Although MRI did not add any further information to that already supplied by the US, the use of cross-sectional imaging in the assessment of SFT is advocated, 9,10 as it may add additional information regarding bone involvement, which may be subtle.…”

This case report discusses the unusual presentation and ultrasound features of a solitary fibrous tumour of the face. Solitary fibrous tumour is an uncommon form of soft tissue tumour which, although seen predominantly within the lung pleura, can occur throughout the body in sites such as the peritoneum, mediastinum and head and neck. Ultrasound is an excellent imaging modality in the assessment of soft tissue masses in the head and neck. The ultrasound features demonstrated by this example of solitary fibrous tumour are reviewed. This report also highlights that ultrasound alone is ultimately limited in reaching a definitive diagnosis. The roles of other investigations such as ultrasoundguided biopsy and cross-sectional imaging are discussed.

A 77-year-old woman was admitted to our Hospital for a mass lesion in the plantar area of the left foot. The patient referred that the mass was present for about 30 years but it had never been treated before because asymptomatic. Foot Magnetic Resonance Imaging (MRI) reviewed a low-signal-intensity tumor on both T1 weighted and T2 weighted images. Based on clinical and diagnostic imaging findings we initially suspected a fibroproliferative neoplasm like an aggressive fibromatosis. Histologically the lesion was benign fibroblastic spindle cell lesion with dense or loose collagen fibers. Cellularity was low and no mitotic figures were found. The tumor cells were positive for CD34, whereas they were negative for α smooth muscle actin, desmin, HHF35 and S100 protein. These pathological findings were consistent with an Extrapleural Solitary Fibrous Tumor (Extrapleural SFT). The Extrapleural SFT should be included in the differential diagnosis of extrapleural lesions in which MRI suggests fibrous content. These entities exhibit a dense fibrocollagenous matrix that can produce low signal intensity on T2-weighted MRI images, similar to Extrapleural SFT. However, in order to reach a proper diagnosis and treatment is essential to integrate a detailed patients' clinical history and to perform a biopsy to collect cells for closer examination.
