Abstract:
Mesenteric cysts are rare cystic malformations of the mesentery. They are usually located at the iliac mesentery. Clinically most mesenteric cysts are asymptomatic, but sometimes they present with non-specific abdominal symptoms. Diagnosis can be aided using US, CT and MRI but careful interpretation of the images and high index of suspicion of this rare condition is essential for the correct diagnosis, which cannot always be preoperatively established. The therapeutic method of choice is complete surgical excision of the cyst which minimizes the possibility of recurrence. Histopathologically they are classified in six group. We present a case of a mesothelial mesenteric cyst in patient with colon cancer. The cyst was misdiagnosed as urinary bladder diverticulum in the preoperative CT scan.
Insights
Mesenteric cysts are rare abdominal growths. This case highlights a mesothelial mesenteric cyst misdiagnosed on CT scan, emphasizing the need for high suspicion in diagnosis.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Diagnostic Imaging
Background:
- Mesenteric cysts are uncommon cystic malformations of the mesentery, often asymptomatic or presenting with vague abdominal symptoms.
- They are typically found in the iliac mesentery, posing diagnostic challenges due to their rarity.
Observation:
- A case of a mesothelial mesenteric cyst in a patient with co-existing colon cancer is presented.
- Preoperative computed tomography (CT) misdiagnosed the cyst as a urinary bladder diverticulum.
Findings:
- Accurate preoperative diagnosis of mesenteric cysts requires high suspicion and careful interpretation of imaging (US, CT, MRI).
- Complete surgical excision is the preferred treatment to prevent recurrence.
- Mesothelial mesenteric cysts represent one of six histopathological classifications.
Implications:
- This case underscores the importance of considering rare diagnoses like mesenteric cysts, even when imaging suggests a more common condition.
- Enhanced vigilance in interpreting abdominal imaging is crucial for accurate diagnosis and timely surgical intervention.
- Improved diagnostic strategies are needed for these rare cystic malformations.
