Infant with soft tissue prominence and small skin
discoloration in the thumb.
MRI (see below): T2 weighted axial image shows
a non-specific hyperintensity in the area (1st MR image). T1
weighted axial MRI demonstrates a slightly
hyperintense (relative to the muscles) lesion in the thumb
(2nd image). Post-gadolinium T1 weighted image shows some
contrast enhancement in the lesion.
MRI is limited in this case; because the area of
interest (thumb) is a small body part and the lesion
is also small in size. In most larger infantile
hemangiomas, MRI can be more helpful in terms of
confirming the suspected diagnosis and also to
outline the margins of the malformation. Most large
infantile hemangiomas demonstrates relatively
homogeneous contrast enhancement and some small
fast-flow vascularity in the periphery of the mass,
as well as in the surrounding soft tissues. Overall,
rare possibilities (e.g., malignancy) can not be
entirely excluded in this case based on this MR
scan. To learn more about MRI scan for these

Final decision should be made based on
clinical history and assessment.
Assuming this is a small infantile hemangioma,
no treatment is needed. No arteriogram is required.
If lesion enlarges significantly unusual to a
typical infantile hemangioma, biopsy may be
indicated. This should should involute in the next
few years with or without minimal sequela. No
sclerotherapy or embolization is indicated.
