An 81-year-old woman suffered from low back pain for a week after lymphoma chemotherapy. Lumbar MRI T₁WI (a) and T₂WI/FS (b) illustrated multiple abnormal vertebral signals with mild compression fractures. The radiologist misdiagnosed it as a malignant lesion because of the patient’s clinical history of malignant tumor, missing some signs of benign compression fracture such as linear low signal under the endplate, strip-like abnormal signal (arrows), and Schmorl’s nodes. This diagnostic bias is classified as anchoring bias and confirmation bias. After the patient underwent vertebral biopsy and arthroplasty (c), no evidence of malignant tumor was found by pathology, and a benign compression fracture was diagnosed
