<Abstract:> Colorectal large villous adenomas are sometimes associated with McKittrick Wheelock syndrome, a condition characterized by severe diarrhea leading to dehydration, electrolyte depletion, and acute renal failure, which can be life-threatening in some cases. The efficacy of radiotherapy for colorectal villous adenoma has rarely been reported. We present a rare case of McKittrick Wheelock syndrome in an older man caused by a large colorectal villous adenoma. This case is notable because palliative external beam radiotherapy of 30 Gy in 10 fractions not only reduced the tumor size but also resulted in significant symptom relief. This report demonstrates the efficacy of palliative radiotherapy for severe colorectal villous adenomas as a valid treatment option, particularly in older patients with complications.
