ABSTRACT
Brain capillary telangiectasia is an incidental vascular malformation found usually in pons and sometimes in extra- pontine sites. Typical MRI features are enhancement on post contrast T1 weighted images and signal loss on gradient echo images. We evaluated 10 patients with various MR techniques. Susceptibility weighted imaging was superior to GRE T2 in showing decreased signal due to susceptibility effects. Diffusion weighted imaging and diffusion tensor imaging proved not useful in the diagnosis.

Desmoplastic fibroma of the bone is a very rare benign tumour, which may be locally aggressive. We report X-ray radiographic and MRI findings of a case of desmoplastic fibroma of the humerus in a 33-year-old man who presented with a slowly enlarging arm mass over years. Desmoid fibroma should be taken into consideration in case of a low T2 signal in a non-sclerotic fibroosseous lesion.
