title: Presacral ganglioneuroma arising in an elderly man with persistent constipation.
abstract: Presacral ganglioneuroma in a 70-year-old man with persistent constipation and its features on computed tomography, magnetic resonance, and endoscopic ultrasonography are presented. Barium enema study and laparotomy showed that constipation was caused mainly by extrinsic compression from this tumor. Computed tomography, magnetic resonance, endoscopic ultrasonographic features such as well-defined solid tumor with a cystic component and punctate calcifications may facilitate early diagnosis of this rare tumor.
