Abstract

A 42-year-old woman presented with local recurrence and distant lung and liver metastases 7 years after resection of a primary intracranial haemangiopericytoma. Whole-body (18)F-fluoro-2-deoxy-d-glucose (FDG)-positron emission tomography (PET)-CT scan showed no increased uptake in local recurrence or distant metastases except for a focus of increased FDG uptake within a hepatic metastasis. The hypermetabolic area correlated with an intratumoral hypoenhancing area on the CT scan. PET-CT scan may be useful to allow further understanding of the tumour.

摘要

一位 42 岁女性在切除原发性颅内血管外皮细胞瘤 7 年后出现局部复发和远处肺及肝转移。全身 (18)F-氟代-2-脱氧-d-葡萄糖(FDG)正电子发射断层扫描(PET)-CT 扫描显示,除了肝转移灶内的一个 FDG 摄取增加的焦点外,局部复发或远处转移均未见摄取增加。高代谢区域与 CT 扫描上肿瘤内的低增强区域相对应。PET-CT 扫描可能有助于进一步了解肿瘤。
