Insights
Gastric duplication cysts (GDCs) can mimic pancreatic pseudocysts, posing a diagnostic challenge. This case underscores the importance of advanced imaging in distinguishing these rare congenital anomalies for accurate treatment.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Congenital Anomalies
Background:
- Gastric duplication cysts (GDCs) are rare congenital anomalies.
- They can present with symptoms overlapping other abdominal cystic lesions.
- Differentiating GDCs from pancreatic pseudocysts is clinically significant.
Observation:
- A 4-year-old girl presented with abdominal pain and distension.
- Initial imaging suggested a pancreatic pseudocyst, leading to endoscopic intervention.
- Subsequent MRI revealed features suspicious for a GDC.
Findings:
- The patient was diagnosed with a gastric duplication cyst.
- Diagnostic confusion arose from similar clinical and initial imaging findings to pancreatic pseudocysts.
- Advanced imaging (MRCP) was crucial for correct diagnosis.
Implications:
- This case highlights the diagnostic challenges in differentiating GDCs from pancreatic pseudocysts.
- It emphasizes the utility of advanced imaging modalities like MRCP.
- Accurate diagnosis is essential for appropriate management and surgical planning of GDCs.
Abstract:
Gastric duplication cysts (GDCs) are rare congenital anomalies that can closely resemble other cystic abdominal lesions, particularly pancreatic pseudocysts. We present the case of a 4-year-old girl with progressive abdominal distension, pain, and elevated serum amylase levels. Initial imaging including an abdominal ultrasound, contrast-enhanced computed tomography, and endoscopic ultrasound, suggested a pancreatic pseudocyst, resulting in an endoscopic cystogastrostomy and stent placement. However, post-procedure magnetic resonance cholangiopancreatography revealed a thick-walled cyst with an inner mucosal lining, raising suspicion for a GDC. Surgical excision confirmed the diagnosis, and the patient had an uneventful recovery. This case highlights the diagnostic challenge of differentiating GDCs from pancreatic pseudocysts due to overlapping clinical and imaging features.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
