A 60-year-old woman diagnosed with stage IIIB cervical cancer (squamous cell carcinoma) underwent radiation chemotherapy. Two months post-treatment, a vaginal speculum examination revealed the cervical tumor had significantly shrunk in size. A cervical cytology test showed atypical cells, but it was challenging to distinguish if they were viable cancer cells. Consequently, an MRI was contemplated to assess the tumor status. If residual disease is detected, a pelvic exenteration may be considered. The challenge lies in discerning—with MR imaging—whether there is any residual disease in need of treatment or whether we are merely observing the effects of the prior treatment.
