MRI appearance of surfers' knot medial to the patients' first MTPJ of the right foot. (A) Coronal T2-fat-saturated acquisition; (B) coronal T1-fat-saturated acquisition; (C) coronal T1-fat-saturated, postcontrast acquisition; (D) coronal gradient echo acquisition; (E) axial proton density-weighted acquisition. The lesion exhibits ill-defined T1 hypointensity and speckled T2 hypointensity, with only mild enhancement after contrast administration. No blooming artifact is evident on gradient echo imaging.
