A rare appendiceal mucinous cystadenoma perforated and mimicked an abscess. This highlights the importance of considering primary appendix neoplasms in diagnosis.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Abdominal Imaging

Background:

  • Appendiceal neoplasms are rare, often presenting with vague symptoms mimicking appendicitis or abscess.
  • Early diagnosis and appropriate management are crucial for favorable outcomes.

Observation:

  • A 58-year-old woman presented with right lower quadrant pain and fever, initially diagnosed as an appendiceal abscess based on CT findings.
  • Despite initial drainage, she developed a recurrent inflammatory mass 23 months later.

Findings:

  • The recurrent mass was treated with percutaneous drainage followed by interval appendectomy.
  • Pathologic diagnosis revealed a perforated mucinous cystadenoma of the appendix.

Implications:

  • This case underscores the necessity of including primary appendix neoplasms in the differential diagnosis for inflammatory right lower quadrant masses.
  • Advanced imaging and thorough histopathological examination are vital for accurate diagnosis of uncommon appendiceal tumors.
