Solitary Fibrous Tumours: Unusual Aspects of a Rare Disease.

BACKGROUND:In literature there are only a few descriptions of the typical presentation of solitary fibrous tumours (SFT) and only a few case reports showing its unusual clinical and radiological features.METHODS:We retrospectively evaluated the computed tomography scans of 36 patients presenting with a histological diagnosis of SFT between 1998 and 2008.RESULTS:We present five cases of SFT with an atypical clinical presentation and radiological features.CONCLUSIONS:SFT can occasionally present with unusual radiological features making a differential diagnosis difficult. Even thought imaging plays a fundamental role in the initial diagnostic approach, final diagnosis in only confirmed by biopsy and histology.
