Case History: A 21-year-old female presented with the complaints of swelling of right shoulder for one year.
The shoulder was non-tender with no evidence of discoloration of overlying skin or varicosity.
Figure 1. Increased soft tissue shadow involving right shoulder, however bones and joint undervision appears normal. No e/o lytic and sclerotic lesion is noted.
Figure 2. Ultrasound of local part shows heterogeneously hypoechoic lesion in deltoid muscle with internal anechoic spaces showing low resistance mural flow during systole and diastole on color Doppler sonograms.
Figure 3. Axial fat-suppressed T2-weighted fast spin-echo image (TR/TE, 4440/34) shows high signal intensity lesion with internal flow voids.Coronal T1 weighted fast field echo image (TR/TE, 740/12) and axial fat suppressed precontrast T1 weighted fast spin echo image (TR/TE, 753/11) shows low signal intensity with internal flow voids.Axial fat suppressed postcontrast T1 weighted fast spin echo image (TR/TE, 753/11) shows intense contrast enhancement with presence of flow voids suggestive of high velocity arterial malformation.
Intramuscular hemangiomas are the most common benign tumors of the deep soft tissue.
Hemangiomas are categorized as capillary, cavernous, and mixed.
Prominent vascular channels can be detected on grey scale and Doppler imaging as well.
MRI may help to differentiate between types of hemangiomas.
Imaging findings of radiograph, ultrasound, and contrast MRI.
