Gastroenteropancreatic neuroendocrine neoplasm - a complex presentation in imaging methods

Area of Science:

• Gastroenterology
• Oncology
• Radiology

Background:

• Neuroendocrine neoplasms (NENs) represent a growing proportion of gastrointestinal tumors due to enhanced diagnostic capabilities.
• Clinical manifestations of NENs are highly variable, depending on the specific tumor type and location.
• Advanced imaging, including radiological and nuclear medicine techniques, is crucial for diagnosing and managing NENs.

Observation:

• A routine abdominal ultrasound in a 65-year-old female incidentally detected a suspicious liver lesion (incidentaloma).
• The case report illustrates the lesion's appearance across various imaging modalities.
• The diagnostic process involved differential imaging, incorporating both radiological and molecular/hybrid methods.

Findings:

• Histological verification confirmed the nature of the liver lesion.
• Follow-up examinations provided insights into the lesion's behavior post-diagnosis.
• The report outlines the subsequent management and treatment strategy based on confirmed findings.

Implications:

• Accurate and timely diagnosis of gastrointestinal NENs is essential for effective patient management.
• Multimodality imaging plays a pivotal role in the differential diagnosis of liver incidentalomas.
• This case underscores the importance of a systematic approach to incidental findings in abdominal imaging for optimal patient outcomes.
