Appendicular Mucocele : High Frequency Sonography Imaging A case report and short review of literature

Abstract

Appendicular mucocele, a cystic mass resulting from a dilated appendiceal lumen caused by abnormal accumulation of mucus that often is not considered when problems of the right quadrant lower abdominal pain are assessed. It is rare entity; occurring in 0.25% of 43,000 appendectomy specimens in one series. A correct preoperative diagnosis is rarely made on the basis of clinical examination. Accurate diagnosis is essential in order to prevent rupture at surgery with development of pseudomyxoma peritonei and predict malignant transformation. We describe high frequency sonography findings that led to the correct preoperative diagnosis confirmed with surgery and histopathological confirmation.
