Intracranial lipomas: Clinical and radiological analysis of 153 cases and review of the literature

Abstract

Aim: It is aimed to describe the localization distribution of lipomas in cases diagnosed with intracranial lipoma, HU value measurements in CT examinations, and point value measurements in MRI and discuss them in the light of the literature. Material and Methods: Cases diagnosed with intracranial lipoma were recorded retrospectively by scanning the radiology database and polyclinic records. The localization of the lipomas was recorded by measuring the HU value on CT imaging and spot value measurements on MRI T2 sequence imaging. The same data were recorded and compared in control radiological examinations. Results: A total of 153 cases were diagnosed with intracranial lipoma, and falx lipoma (n:72) was the most common. Intra-calvarial lipoma, which was not defined in the literature, was detected in 21 cases. In CT examinations, the mean HU value at the time of initial diagnosis was -57.91 +/- -12.81; In the examination of MRI T2 sequences, it was recorded as 1384.23 +/- 101.62. In control radiological examinations, no statistically significant difference was detected between HU values in CT examinations and point values in MRI examinations. Discussion: It was determined that intracranial lipomas did not differ in their quantitative radiological examinations. Epilepsy resistance to medical treatment is observed in almost all cortical lipomas. Association with central nervous system anomalies is seen only with callosal lipomas.
