Large Mucocele of the Appendix Discovered in a 48-Year-Old Male Presenting With Appendicitis: A Case Report
The appendix is a vermiform-like organ that extends from the cecum and has been thought of as having a rudimentary immunologic function. However, the appendix can become distended and mucus-filled, classifying it as a mucocele appendix. Mucoceles can be found in various locations in the body, including the colon and the appendix, and have malignancy potential.
We report a case of a 48-year-old male that presented to the ED with a history of two days of abdominal pain. Upon arriving at the ED, he had a CT scan showing a 9.5 x 4.2 x 6.4 cm fluid collection in the right lower quadrant (RLQ) juxtaposed to the cecum, suggesting appendicitis or an abscess. Initially, a laparoscopic approach was taken, which was then converted to an open laparotomy. The mass was excised and a right hemicolectomy was performed along with an ileocolonic anastomosis due to extensive involvement of the large intestine. Pathology reported a low-grade appendiceal mucinous neoplasm resected with negative margins and 16 negative lymph nodes.
