Which bruise pattern is most suggestive of nonaccidental injury?

• A. In a straight line
• B. Circular pattern bruises
• C. Random bruising
• D. A patterned bruise is not suspicious

Answer: (A)

Bruises tell you not just how hard the skin was hit, but also how the force was applied. A straight-line bruise is most telling because it suggests the skin was swept by a long, slender object in a single path, leaving a uniform mark. This pattern is much more characteristic of intentional harm than of typical accidental bumps, which usually produce irregular, scattered bruises rather than a clean line. Circular bruises can occur from hitting with round objects, but they’re not as consistently associated with abuse as a linear pattern. Random bruising is nonspecific and can come from various nonabusive causes, so it doesn’t point strongly to nonaccidental injury. And stating that a patterned bruise is not suspicious conflicts with the reality that many patterned injuries raise concern for possible abuse.
