Summary
Cystic liver metastases from carcinoid tumors are rare. This case highlights a neuroendocrine tumor initially misdiagnosed as a hepatic abscess, emphasizing the need for thorough investigation of unusual liver lesions.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Carcinoid tumors commonly metastasize to the liver, typically presenting as solid, hypervascular lesions.
- Cystic presentations of hepatic carcinoid metastases are exceptionally rare and can mimic other conditions like abscesses.
Observation:
- A 48-year-old female presented with a large hepatic mass initially diagnosed as a hepatic abscess based on imaging.
- Ultrasound-guided biopsy revealed a well-differentiated grade 1 neuroendocrine tumor, prompting further investigation for the primary source.
Findings:
- A CT scan identified an endobronchial mass in the right lower lobe of the lung.
- Biopsy confirmed the lung mass as a typical carcinoid tumor, establishing the primary source of the hepatic metastases.
Implications:
- This case underscores the importance of considering neuroendocrine tumors in the differential diagnosis of cystic liver lesions, even when they mimic abscesses.
- Accurate diagnosis through biopsy and advanced imaging is crucial for appropriate management of rare metastatic carcinoid presentations.
