Case in brief
A 68-year-old woman presented with a right inguinal mass. Ultrasonography revealed the appendix within a femoral hernia sac, characterized by a tubular hypoechoic structure with inflammatory changes. Contrast-enhanced CT showed a cystic mass with enhancing walls, suggestive of an appendiceal mucinous neoplasm. Intraoperatively, a De Garengeot's hernia was confirmed, and pathology identified a low-grade appendiceal mucinous neoplasm.
What made this case unusual
The presence of a low-grade appendiceal mucinous neoplasm within a De Garengeot's hernia is exceptionally rare, making this case noteworthy.
Diagnostic / clinical pearl
Clinicians should consider the possibility of appendiceal neoplasms in patients with femoral hernias, especially when imaging reveals atypical features.
Why it matters
This case underscores the importance of using both ultrasonography and CT to enhance the preoperative diagnosis of femoral hernias and associated pathologies.
