Acute appendicitis revealing a giant mesenteric pseudocyst: case report

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Abdominal Imaging

Background:

• Mesenteric pseudocysts are rare, benign childhood tumors with low incidence.
• Accurate preoperative diagnosis of mesenteric pseudocysts presents a significant clinical challenge.

Observation:

• A case report of an 11-year-old boy presenting with acute appendicitis and intermittent abdominal pain.
• Incidental intraoperative finding of a giant mesenteric pseudocyst during exploratory laparotomy for suspected appendicitis.

Findings:

• The patient was diagnosed with uncomplicated acute appendicitis and a giant mesenteric pseudocyst.
• Successful surgical management involved open resection of the cyst and appendectomy.

Implications:

• This case underscores the importance of maintaining a high index of suspicion for mesenteric pseudocysts in pediatric patients with nonspecific abdominal symptoms.
• Enhanced awareness and diagnostic vigilance are crucial for timely and appropriate management of these rare conditions.
