“…Ultrasound is the firstline diagnostic modality for patients with acute abdominal pain or mass. Different sonographic findings of AM and AA have been described [3,16,17] . Appendix diameter 15 mm or more in USG examination has been determined as the threshold for AM diagnosis with a sensitivity of 83% and a specificity of 92% [3] .…”

Case 1An 82-year-old man was admitted to the hospital because of pain in the right lower quadrant of the abdomen for 3 d. Standard laboratory tests, serum levels of CA 19-9 and carcino-embryonic antigen (CEA) were within normal ranges. Ultrasonography (USG) and computerized tomography (CT) demonstrated a well demarcated, elliptical 7 cm × 5 cm cystic mass with parietal calcifications in the right lower quadrant of the abdomen. There was an indentation in the cecum by colonoscopy. Surgical exploration revealed the mass to be an AM. Simple appendectomy was performed. Pathological examination revealed a mucinous cystadenoma with dimensions of 8 cm × 6 cm × 5.5 cm. AM restricted to the appendix and cecum was free of the disease. The patient's postoperative course was unremarkable, and he was discharged home on the 4th postoperative day. Case 2A 65-year-old woman was referred to the emergency de- CASE REPORT AbstractThe mucocele of the appendix is an uncommon disorder which is often asymptomatic but sometimes causes acute appendicitis-like symptoms. Sometimes, patients with mucocele can present with confusing symptoms. Preoperative suspicion and diagnosis of appendiceal mucocele are important. Ultrasonography and computed tomography are useful tools for the diagnosis of appendiceal mucocele. It may be also recognised by colonoscopy as a smooth submucosal lesion of the cecum. Optimal management of the mucocele could be achieved through accurate preoperative diagnosis. Preoperative diagnosis is a major component for minimizing intra-operative and post-operative complications. We herein report five cases and discuss the diagnostic methods and surgical treatment.

“…Ultrasound is the first line diagnostic modality for patients with acute abdominal pain or mass. Different sonographic findings of appendiceal mucocele and acute appendicitis have been described (16)(17)(18). Outer diameter of appendix 15mm or more in USG examination has been described as the threshold for the diagnosis of appendiceal mucocele with a sensitivity of 83% and a specificity of 92% (16), while for acute appendicitis it has been established as 6mm (19).…”

ABSTRACT:The mucocele of the Appendix is an uncommon cystic lesion characterised by distension of the appendiceal lumen with mucus. The incidence ranges from 0.3% to 0.7% of all appendectomied specimens. OBJECTIVE: We report here the demographic, clinical, radiologic, histopathologic, preoperative and postoperative findings and outcome of patients of mucocele of the appendix diagnosed on histopathologic examination. METHODS: We retrospectively analysed the hospital records of all the patients whose appendectomy was done and had a histopathological diagnosis of mucocele of the appendix. RESULTS: A total of 885 patients with the preoperative diagnosis of appendicitis were admitted and surgically treated in our centre from April'2004 to September'2012 and 13 (1.47%) patients were diagnosed to have mucocele of the appendix on histopathologic examination. Average age of presentation was 53yrs (range 17yrs -85yrs). 6(46.15%) patients were male and 7 (53.85%) were female with M: F ratio 0.86:1. The most common presentation was right lower quadrant pain in 7 (53.85%) patients. 2(15.38) patients presented with generalised abdominal pain, distension of abdomen and loss of appetite while 4(30.77%) patients were asymptomatic. In preoperative ultrasonographic examination, appendiceal cystic masses were diagnosed in 7 (53.85%) patients. Histopathologic examination revealed simple mucocele in 7 (53.85%) patients, mucinous cystadenoma in 5 (38.46%) and mucinous cystadenocarcinoma in 1(7.69%) patient. Two patients of mucinous cystadenoma were diagnosed with complication of pseudomyxoma peritonei. No mortality was noted in any of the patient postoperatively and on follow up. CONCLUSION: Mucocele of the appendix is a rare disease and is usually diagnosed on histopathologic examination of Appendectomied specimens. As there is potential for malignant transformation and pseudomyxoma peritonei due to rupture of the mucocele, extensive preoperative evaluation and thorough intraoperative gastrointestinal, ovarian & peritoneal examination is required.
