Which finding would indicate no hematoma or hemorrhage on CT interpretation?

• A. Blood - no hematoma/hemorrhage
• B. Blood present with hematoma
• C. Cisterns with blood in spaces
• D. Ventricles asymmetrical

Answer: (A)

On CT, acute hemorrhage shows up as a focal, bright (hyperdense) area within brain tissue or in spaces around the brain. A hematoma is a discrete collection of blood, and hemorrhage can occur in the parenchyma, subdural/epidural space, subarachnoid space, or ventricles. If the scan shows blood but there is no localized blood collection forming a hematoma or filling a hemorrhagic space, then there is no hematoma or hemorrhage present. The statement in question describes blood without a mass effect or a defined bleeding collection, which corresponds to no acute hemorrhage detected. In contrast, finding blood within the cisterns or spaces, or mismatched ventricles, would indicate actual hemorrhage or its consequences.
