Solitary Fibrous Tumor of the Central Nervous System: A Report of Two Cases with Emphasis on Diagnostic Pitfalls

Figure 1

MRI images of a 57-year-old black female who presented with a history of headaches with no neurological deficits, after being involved in a pedestrian-vehicle accident. There is well well-circumscribed intraventricular lesion obstructing the foramen of Munro, with resultant hydrocephalus, thus VP shunt (red arrow) in situ. The lesion is isointense to the brain on T1 (a) and heterogeneous on T2 (b). Avid contrast enhancement is noted in (c) and (d). Diffusion-weighted imaging demonstrated restricted diffusion (e and f).
