Muscle Recurrence of a Primarily Nodal Follicular Lymphoma Studied by Contrast-Enhanced 18F-FDG PET/CT

We report the case of a 52-year-old woman with follicular lymphoma localized in the left inguinal region without any extranodal involvement and achieving a complete response after radiotherapy. After a 3-year disease-free interval, muscular recurrence at the left arm was shown by contrast-enhanced 18F-FDG PET/CT. Contrast-enhanced 18F-FDG PET/CT performed after immunochemotherapy documented complete disease remission. Lymphoid tissue is usually not present in the skeletal muscle, making muscular lymphomatous involvement quite unusual; muscular relapse of a primarily nodal lymphoma is even rarer.
