Abstract

This report describes the clinical features, diagnostic and treatment modalities of a 62-year- old female patient with liver metastasis and local recurrence of meningeal hemangiopericytoma (HPC), who presented with the clinical manifestations of memory deterioration, visual reduction and abdominal mass for one month. Skull and abdominal computed tomography (CT), magnetic resonance imaging (MRI) and 18FFluorodeoxyglucose positron emission tomography (FDG-PET)-CT were used for pre-surgery identification. Lesions without FDG uptake and less tumoral viability was observed through FDG-PET- CT, which was characteristic features of HPC before operation. The intraoperative specimens from the liver resection and the calvarium were pathologically examined for further confirming the diagnosis. The patient underwent liver resection and bilateral frontal cerebral convex and parafalx resection as well as intracranial pressure sensor implantation for liver metastasis and local recurrence of HPC respectively. The patient recovered well and no recurrence or distant metastasis was found after 2-year follow-up. Early diagnosis and long-term follow-up are crucial for patients with hepatic metastasis or local recurrence of HPC, and FDG- PET-CT is recommended as an ideal imaging tool. Radical resection of HPC lesions is considered as an optimal treating approach.
