There are a variety of reasons that a person can have a pathologic fracture. A simple bone cyst, metastasis, or other lesion that replaces normal bone can make the bone more susceptible to injury. Relatively mild stress from normal activities or minor trauma, such as getting a finger caught in a door (as in this patient) may cause a fracture.
More aggressive processes can appear similar, so this is a great example of why the radiologist needs to know what's going on with the patient.
