Abstract: Solitary metastasis or oligometastasis to the patella from colorectal cancer is rare, and multimodal imaging findings, including MRI, have not been well discussed. We report the case of a 74-year-old man with patellar oligometastasis from rectal cancer that was initially missed on whole-body positron emission tomography (PET) and misdiagnosed on bone scan. Radiographs and CT scans showed an osteolytic patellar tumor that was hypointense with ill-defined borders on T1-weighted imaging and hyperintense with well-defined borders on diffusion-weighted imaging. We discussed the characteristic MRI findings of patellar metastases and the pitfalls of PET and bone scan.
