Introduction:
Primary hepatic neuroendocrine tumors (PHNETs) are extremely rare, having less than 200 cases reported in the literature.
Presentation of case:
A 51-year-old woman presenting with mild intensity sharp pain in the upper abdomen that started 4 years ago. Preoperative Magnetic Resonance Imaging (MRI) suggested hepatocellular adenoma. Surgical exploration found a tumor occupying the whole segment IV of the liver, therefore a left hepatectomy was performed. Pathology and immunohistochemistry indicated to be a low-grade neuroendocrine tumor of the liver. The patient is enjoying a good quality of life, free of disease, presenting no signs of recurrence nor metastases 12 months after the procedure.
Conclusion:
The clinical presentation of PHNETs is non-specific and its radiologic features are intensely diversified, frequently leading to misdiagnosis of other hepatic neoplasms.
