Q.A young patient undergoes MRI of brain which show no abnormality on
unenhanced SE images. The pons reveals lacelike region of stippled contrast
enhancement on contrast study .The patient is asymptomatic.The most likely
diagnosis is
a.lymphoma
b.cavernous angioma
c.capillary telangiectasia
d.venous angioma
e.developmental venous anomaly
ANS.---c
The key to distinguishing the enhancement of capillary telangiectasia from other, similar enhancing lesions, notably lymphoma when periventricular, is the absence of any signal abnormality on the unenhanced images.
