“…CT can determine the relation between lesion and the neighbouring organs, and help confirm the diagnosis [15,16,19,20] . CT reveals a cystic mass with enhancing wall nodularly in the expected area of the appendix, especially in older patients, in whom AM should be considered [9,15,16,21] . AM could be visualized by CT in three of our patients.…”

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.

“…Mucoceles, both benign and malignant, can be complicated by a superimposed infection, which causes gas bubbles or an air-fluid level within the mass (5,6,7,18,25). mucinous cystadenocarcinoma (4,15,16). Furthermore, mesenterial infiltration, peritoneal implants with or without omental cakes, and ascites are also signs that suggest a malignant origin (Fig.…”

Mucocele of the appendix is a descriptive term of a distended, mucus-filled appendix caused by various conditions, both benign and malignant. Computed tomography is the imaging modality of choice. Correct pre-operative diagnosis is important because of the possibility of peroperative rupture and subsequent development of pseudomyxoma peritonei. It is the task of the radiologist to alert the clinician and surgeon to the presence of this entity, the potential associated complications and possible signs of malignancy.

“…Appendiceal mucinous adenocarcinomas are associated with a higher incidence of perforation than appendiceal mucinous adenomas [17,18]. Perforation can lead to diffuse peritoneal spread (so-called pseudomyxoma peritonei syndrome) or a localised sealing off around the appendix [17,18].…”

“…In addition, while size, shape, wall thickness, septations and wall calcification are not helpful in differentiation of malignant from benign mucinous neoplasms, the finding of a cystic dilated appendix with enhancing wall nodularity, particularly in older patients, may indicate the presence of mucinous cystadenocarcinoma [17]. Perforated mucinous tumours appear as a dilated appendix with a focal wall defect, periappendiceal fat stranding and diffuse or localised low-attenuation mucinous fluid.…”

ABSTRACT. Perforation usually requires emergency surgery and may affect the prognosis of patients with gastrointestinal tumours. Accurate pre-operative diagnosis of these conditions is important because proper management such as curative surgical treatment may be needed. The aims of this article are to illustrate CT appearances of perforated tumours of the gastrointestinal tract and to discuss their impact on clinical management.
