Background:

Hepatic angiomyolipoma is a rare mesenchymal tumor of the liver, distinct from its more common renal counterpart.
These tumors exhibit variable compositions of vascular, fatty, and muscle tissues, leading to diagnostic challenges.
Hepatic angiomyolipomas are often asymptomatic and can be mistaken for other liver malignancies on imaging.

Observation:

A 64-year-old female presented with vague abdominal pain and a liver lesion suspicious for hepatocellular carcinoma.
Despite negative tumor markers, a left lateral sectionectomy was performed.
Histopathological examination revealed the lesion to be an angiomyolipoma.

Findings:

The resected liver lesion was diagnosed as angiomyolipoma through histological and immunohistochemical analysis.
The patient experienced an uncomplicated postoperative recovery.
No signs of recurrence were observed during follow-up.

Implications:

This case underscores the diagnostic difficulties associated with hepatic angiomyolipoma, emphasizing the importance of definitive histopathological diagnosis.
Surgical intervention, even with an initial misdiagnosis, can lead to favorable outcomes.
Regular long-term follow-up is crucial for patients with hepatic angiomyolipoma to monitor for potential recurrence.
