Novel Development of a Large Cerebral Cavernous Malformation in an Adolescent With a History of Familial Cerebral Cavernous Malformation Syndrome

TL;DR

A 16-year-old girl with a family history of cerebral cavernous malformations developed a new large lesion in her brain during adolescence.

Contribution

This case highlights the potential for new cavernoma development in adolescents with familial CCM syndrome.

Findings

A large cavernoma was found in the right frontal lobe of a 16-year-old girl with familial CCM.

The lesion was not present in an MRI scan from eight years earlier.

The case shows that new cavernomas can develop later in adolescence.

Abstract

Cerebral cavernous malformations (CCM) are capillary vascular malformations of the central nervous system (CNS). These lesions can be either familial or sporadic. We present a case of a 16-year-old girl with familial CCM syndrome who presented with a six-month history of chronic headaches. A magnetic resonance imaging (MRI) scan revealed a large cavernoma in the right frontal lobe that had not been present on a prior scan performed eight years earlier. This case presentation demonstrates the possibility of significant novel cavernoma development further into adolescence.
