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 th
at constipation was caused mainly by extrinsic compression from this tumor.
Computed tomography, magnetic resonance, endoscopic ultrasonographic featu
res such as well-defined solid tumor with a cystic component and punctate c
alcifications may facilitate early diagnosis of this rare tumor.
