Ectopic gastric duplication cyst in an infant.

Area of Science:

• Pediatric Surgery
• Diagnostic Imaging
• Gastrointestinal Pathology

Background:

• Ectopic gastric duplication cysts are rare congenital anomalies.
• These cysts can present as abdominal masses, sometimes mimicking other intra-abdominal pathologies like pancreatic lesions.
• Accurate preoperative diagnosis is crucial for appropriate surgical planning and management.

Observation:

• A case report details a 10-week-old infant with a superficial left upper quadrant mass.
• The mass was identified as an ectopic gastric duplication cyst originating from the pancreas.
• Preoperative imaging included ultrasound and technetium scan.

Findings:

• Ultrasound revealed a cystic lesion with specific echogenic (mucosa) and anechoic (muscle) layers.
• The technetium scan confirmed the presence of gastric-type mucosa within the cyst.
• These imaging findings were deemed specific for gastric duplication cyst.

Implications:

• Ultrasound findings, characterized by distinct echogenic and anechoic layers, are highly suggestive of gastric duplication cysts.
• Combined ultrasound and technetium scintigraphy can reliably characterize these lesions preoperatively.
• This diagnostic approach can potentially obviate the need for more invasive investigations, guiding surgical intervention effectively.
