  		Fig. 4C —Ruptured epidermal cyst in right greater toe in 16-year-old girl with recent pain. Gadolinium-enhanced fat-suppressed T1-weighted image (578/20) shows mass with thick irregular peripheral rim enhancement and septal enhancement (thick arrow). Fuzzy soft-tissue enhancement (thin arrow) is also shown around mass.

  		Fig. 5C —19-year-old man with painful ruptured epidermal cyst in left posterior shoulder. Gadolinium-enhanced fat-suppressed T1-weighted image (516/12) shows mass with very thick and irregular peripheral enhancement (thick arrow). Subtle soft-tissue enhancement (thin arrow) is present near mass.
