title: Cystic coccygeal medullary vestige presenting as a sacrococcygeal mass: a case report and MRI findings.
abstract: The case of a 10-month-old boy with a cystic coccygeal medullary vestige is presented. Although the MRI findings of this lesion resemble those of sacrococcygeal teratomas, the presence of a cystic component located at the tip of the coccyx and associated sinus formation may help in diagnosing it. Cystic coccygeal medullary vestige should be entertained in the differential diagnosis of coccygeal cystic lesions.
