Hemangiopericytoma is a rare primary tumor originating from Zimmerman’s pericytes, with signifcant metastatic potential. Hepatic metastatic disease requires an aggressive approach by a multidisciplinary team of dedicated oncology specialists, to prolong survival in selected patients. We report on a patient with recurrent hepatic metastases of grade II intracranial hemangiopericytoma 5 years afer initial treatment, managed by a stepwise combination of liver resection, radiofrequency ablation, and transarterial embolization. Although metastatic disease implies hematogenous dissemination, long-term survival afer liver resection has been reported and major hepatectomies are justifed in patients with adequate local control. Liver resections combined with transarterial embolization are highly recommended, due to hypervascularity of the tumor. 1. Introduction Noncolorectal, nonneuroendocrine hepatic metastases are a diverse group of secondary liver neoplasias, exhibiting vari- able clinical behavior and characteristics. Particularly in cases of rare primary tumors, where limited datasets are available and no ofcial guidelines are published, a multidisciplinary team (MDT) approach is mandated, to provide comprehen- sive assessment, consultation, and treatment. We present our experience with a case of recurrent hepatic metastases from an intracranial hemangiopericytoma (HPC), managed by an MDT of oncologic surgeons, med- ical oncologists, interventional radiologists, and dedicated pathologists. 2. Case Presentation A 23-year-old Caucasian male underwent a right tempo- ral lobe glomus tumor excision. Seven years later he was diagnosed with local recurrence and underwent two cran- iotomies to achieve radical resection (Figure 1). Histopathol- ogy revealed an HPC grade II. No adjuvant chemoradiother- apy was instituted. Five years afer the last intervention, he was admitted to hospital due to diverticulitis and an incidental fnding ofa small lesion in the body of T10 vertebra was demonstrated on CT scans, as well as multiple, atypical, hypervascular lesions in both liver lobes, the larger being 8 cm in diameter, initially considered hemangiomas (Figures 2 and 3). Magnetic reso- nance imaging, however, was consistent with metastatic HPC lesions rather than benign hemangiomas. Although positron emission tomography (PET) revealed strong uptake of the contrast medium in the T10 lesion, no uptake in the liver was documented. Tumor markers (CEA, FP, and Ca19-9) were within normal limits. A right hepatectomy plus radiofrequency ablation of one lesion in the lef lobe was decided and the patient had an uneventful postoperative course. Histopathology revealed two tumors (8.7 cm and 3.8 cm) consisting of relatively bland Hindawi Publishing Corporation Case Reports in Oncological Medicine Volume 2015, Article ID 214306, 5 pages http://dx.doi.org/10.1155/2015/214306
