Case Report: Whispers of the serpent: exploring uncommon imaging features in primary hepatic malignant mesothelioma.

Primary hepatic malignant mesothelioma (PHMM) is an uncommon and aggressive neoplasm with vague clinical and radiological features, posing challenges for preoperative diagnosis. In our case, a lobulated hepatic mass demonstrated a serpiginous peripheral enhancement pattern on contrast-enhanced CT and MRI. This uncommon imaging manifestation has been sporadically documented in previous reports. By consolidating these findings, our report emphasizes serpiginous peripheral enhancement as a potential diagnostic clue for PHMM. Recognition of this pattern may aid earlier detection, improve differential diagnosis, and guide timely surgical decision-making in affected patients.
