A rare case of double lipoma of the corpus callosum: a clinical case report

Abstract

INTRODUCTION: Intracranial lipoma is an extremely rare congenital anomaly accounting for less than 0.1% of intracranial tumors, and is due to abnormal differentiation of the meninx primitiva. It is not considered to be a true neoplasm.

AIM: To present a clinical case of double lipoma of the corpus callosum with parts of which belonging to two different types of lipomas.

The article discusses a variant of intracranial lipoma — lipoma of the corpus callosum. There are two main types of corpus callosum lipomas: curvilinear and tubulonodular. As a rule, the first type is asymptomatic and is an incidental finding during examination. The second type is often associated with abnormal development of the frontal lobes, eyes, calcifications, and also with hypogenesis or agenesis of the corpus callosum. Conservative management is recommended, since the surgical intervention is associated with a high risk of complications due to tight adjacency of lipomas to the neighboring tissues, which contain important neurovascular structures.

CONCLUSION: The presented clinical example demonstrates an incidental finding: an unusual variant of double lipoma with an asymptomatic course. Such a variant was not found in the literature. It was decided to carry out treatment of the main disease without any actions for double lipoma of the corpus callosum.
