Background. Appendiceal mucinous neoplasms (AMN) are rare tumors (<1%) with variable malignant potential, with unpredictable biological potential to spread into the peritoneal cavity in the form of gelatinous mucin deposits. Advanced disease presents with pseudomixoma peritonei. Objective of the study. Analysis of imaging methods in establishing the diagnosis and differential diagnosis of mucinous neoplasms with other forms of appendicular tumors. Material and Methods. AMN in most cases are detected occasionally during imaging, endoscopic investigations or during laparotomy and laparoscopic interventions performed with other indications. Early diagnosis of AMN is essential, ultrasonography and computed tomography being the most useful investigations for this purpose. Results. Ultrasonography (USG) and computed tomography (CT) are imaging investigations that facilitate the preoperative diagnosis of AMN. USG is of first intention, with a sensitivity of 83% and specificity of 92%, it can identify a cystic mass with different echogenicity. Multiple echogenic layers and dilation of the appendix exceeding 15 mm will appear as "onion-skin" and may be pathognomonic for AMN. CT is the method of choice for the diagnosis of AMN, can highlight well-circumcised cystic masses, intramural calcifications(in 50%) and can demonstrate the involvement of adjacent organs. Barium enema allows to highlight the presence of filling or ulceration defects. Conclusion. USG and CT are useful for the diagnosis of appendicular mucinous neoplasms. CT has an increased accuracy compared to USG, however the results of the investigations are nonspecific and require differentiation with other intra-abdominal tumor masse |
