PET-CT visualization of intracranial lipomas

Intracranial lipomas are rare lesions, infrequently indicated for neurosurgical treatment due to their benign course and significant surgery-related complications rate. The aim of this study was to collect, describe and analyze the patients with intracranial lipomas verified by PET-CT and reported in the literature up to date. The literature search was performed through Pub Med using the combination of the terms intracranial lipomas, CT, MRI and PET-CT. The thorough review of the relevant papers did not find even one case with PET-CT images of intracranial lipomas. The first two personal illustrative cases were demonstrated by our report. The value of PET-CT in the primary and differential diagnosis of intracranial lipomas was analyzed, in comparison with CT, MRI and PET-MRI.
