Stereotactic Biopsy of a Cerebral Capillary Telangiectasia after a Misleading F-18-FET-PET^[*]

Introduction

An increasing number of cerebral MRI investigations are performed in patients with relatively nonspecific complains such as headache or dizziness. Occasionally these scans reveal incidental findings such as aneurysms, meningiomas, or even intrinsic lesions.[3] Usually, after some months, a follow-up MRI is performed in these patients. However, positron emission tomography with O-(2-[F-18]-fluoroethyl)-l-tyrosine (FET-PET) has been reported as an effective method for predicting the clinical course by detecting gliomas with high specificity in the setting of incidental intrinsic lesions.[2] [3] [10]

Here we report on a patient with an incidental, highly eloquently located cerebral lesion of high-FET uptake that prompted a stereotactic biopsy of a capillary telangiectasia (CTA).
