Giant Recurrent Sacral Chordoma
A 65-year-old man presented with a giant recurrent sacral chordoma after undergoing 7 surgical resections. Neurologic examination revealed urinary incontinence. Magnetic resonance imaging showed a huge mass lesion in the bilateral gluteal regions and multiple metastatic chordomas. Colostomy and wide en bloc excision of the giant recurrent chordoma were performed in April 2017. The tumor weighed 13.15 kg, and histopathologic examination revealed a chordoma. Magnetic resonance imaging performed at the 12-month follow-up showed slight recurrence. In addition, multiple metastatic chordomas localized to the pelvic cavity and the subcutaneous layer of the gluteal region showed significant enlargement. The metastatic chordomas were resected in May 2018. At his last follow-up, the patient presented with an indwelling catheter and a colostomy bag, and the recurrent chordoma showed no visible enlargement.
