Elastofibroma dorsi is a slowly growing tumour-like process composed o
f an ill-defined mass of fibro-elastic tissue. It occurs almost exclus
ively in the elderly and is thought to result from mechanical friction
, It has received little attention in the radiological literature and
is considered a rare lesion. With indications for computerised imaging
expanding, elastofibroma dorsi will probably be seen more frequently.
This report describes an elastofibroma presenting in an 11-year-old g
irl and its appearance by magnetic resonance imaging. Presumptive diag
nosis by magnetic resonance imaging may prevent unnecessary radical su
rgery.
