Key result
Pre-operative F-FDG PET/CT showed no distant metastasis in a patient with primary hepatic malignant fibrous histiocytoma, whereas post-operative imaging revealed multiple metastases.
Case Report (n=1)
F-FDG PET/CT demonstrates utility in evaluating metastasis in primary hepatic malignant fibrous histiocytoma, highlighting the potential for rapid post-operative progression.
Pre-operative F-FDG PET/CT may miss metastases in primary hepatic MFH; leaves open need for improved staging strategies in this rare tumor.
Malignant fibrous histiocytoma is mainly presented in extremities, less commonly in posterior peritoneum, but primary presented in liver is very rare and often with a poor prognosis because of its high aggression. The features of clinical presentations and images are variable and the pre-operative diagnosis is difficult. Here, we report a primary hepatic malignant fibrous histiocytoma patient with no distant metastasis showed on pre-operative F-FDG PET/CT, however with many metastases showed on the post-operative F-FDG PET/CT.

Liu et al. (2018) conducted a case report in Primary hepatic malignant fibrous histiocytoma (n=1). F-FDG PET/CT was evaluated on Detection of metastases. Pre-operative F-FDG PET/CT showed no distant metastasis in a patient with primary hepatic malignant fibrous histiocytoma, whereas post-operative imaging revealed multiple metastases.
