title: Mucinous cystadenoma of the appendix with unusual sonographic appearances.
abstract: A case of an appendiceal cystadenoma resulting in a large mucocele in a 35 year old man presenting with abdominal pain is reported. On ultrasonography, an unusual appearance of strand-like layers of varying echo-texture suggesting a solid lesion was seen. On computed tomography, calcification and contrast enhancement of the rim was noted. The spectrum of imaging appearances of appendix mucoceles is reviewed.
