Clinical Report: A Liver Nodule Exhibiting Arterial Enhancement and Washout
Background
Liver nodules can present diagnostic challenges, particularly in patients with underlying liver disease. Differentiating between various types of hepatic tumors is crucial for appropriate management, especially in cases where imaging suggests malignancy. Primary hepatic GISTs are exceedingly rare, with only approximately 40 cases reported in the literature.
Data Highlights
No numerical or trial data presented in the article.
Key Findings
A 5.3-cm hepatic nodule was detected in a patient with MetALD.
Dynamic contrast-enhanced MRI showed arterial phase hyperenhancement and washout, consistent with LI-RADS 5.
Histopathological analysis revealed spindle-shaped tumor cells, confirming a diagnosis of primary hepatic GIST.
The patient underwent laparoscopic left hemihepatectomy followed by adjuvant imatinib therapy.
Primary hepatic GISTs are exceedingly rare.
Clinical Implications
Clinicians should consider rare hepatic tumors like GIST in patients with chronic liver disease when imaging suggests HCC. Accurate diagnosis is essential for determining the appropriate treatment strategy.
Conclusion
This case highlights the importance of considering a broad differential diagnosis for hepatic nodules in patients with complex liver disease histories.
