Necrotising fasciitis (NF) resulting from sigmoid perforation is rare, but none the less remains life threatening. Early surgical intervention and empiric broad-spectrum antibiotic remains the standard of care. A 65-year-old man with history of stage 4 rectal cancer presented with bilateral hip pain. An X-ray of the hip and pelvis to rule out fracture revealed abnormal gas pattern overlying the right hip. CT imaging revealed distal sigmoid perforation with air extending from the pelvis to posterior aspect of the right hip and thigh. Aggressive surgical intervention and antibiotic initiation was associated with successful outcomes in our patient. Although less common, sigmoid perforation leading to NF in posterior thigh is a reminder of a potentially lethal complication.
