FDG PET/CT findings in recurrent malignant schwannoma.

ABSTRACT

Malignant schwannoma is an uncommon but aggressive sarcoma that most commonly arises in young and middle-aged adults. We present a 28-year-old male patient with a recurrent chest wall malignant schwannoma. An FDG PET/CT was performed to evaluate the management of the patient. The PET/CT images showed hypermetabolic mass lesions in the left upper chest wall and increased FDG uptake in the left axillary region. The pathologic results confirmed the PET findings. We conclude that FDG PET/CT could play an important role in the staging, restaging, and post-therapy follow-up of malignant schwannomas.
