Low-grade appendiceal neoplasm presenting as a volvulus of the cecum

Area of Science:

• Gastroenterology
• Surgical Pathology
• Abdominal Imaging

Background:

• Mucocele of the appendix is a rare condition, often asymptomatic, but can present with symptoms similar to acute appendicitis.
• Appendiceal mucoceles (AM) have evolved pathological classifications, moving beyond simple benign/malignant distinctions.
• Volvulus of a benign appendiceal mucocele is exceptionally rare.

Observation:

• This case presents a unique instance of a low-grade appendiceal mucinous neoplasm.
• The neoplasm led to a volvulus, specifically involving the cecum.

Findings:

• The study documents the first reported case of a low-grade appendiceal mucinous neoplasm causing cecal volvulus.
• This finding expands the spectrum of known complications associated with appendiceal mucoceles.

Implications:

• Highlights the importance of considering rare complications in appendiceal mucocele diagnosis and management.
• Suggests that appendiceal mucinous neoplasms, even low-grade ones, can lead to significant secondary complications like volvulus.
• Emphasizes the need for thorough evaluation in cases of appendiceal mucocele to rule out or manage potential complications.
