Abstract

A 59-year-old woman was found to have a 4 cm multi-lobulated mass arising from the posterolateral rectal wall with an adjacent prominent mesorectal lymph node. Correlative CT, MRI and FDG-PET studies were performed, with intense
FDG avidity in the rectal lesion and FDG uptake in the lymph node. Core biopsy favoured an atypical transitional cell/squamoid carcinoma, probably arising from a tailgut cyst. The patient was treated with definitive chemoradiotherapy with no evidence of residual/recurrent disease on repeat FDG-PET.
