This is a young lady with a middle phalangeal enchondroma presenting as an osteolytic expansile lesion. The radiograph and the MRI are characteristic.
These are invariably asymptomatic and often incidentally discovered. However trivial trauma as in her case can cause a fracture through the lesion, at which point it starts becoming really painful. While most phalangeal enchondromas are “touch me not” lesions, when they fracture and become painful, they often need to be operated upon.
