Background: Cavernous angiomas or cavernomas, are vascular malformations usually located in the brain parenchyma. However, they rarely present as extra-axial lesions, attached to the dura, and may mimic meningiomas. Most reported cases concern the cavernous sinus region and other locations are very uncommon. We present a case of giant calcified extra-axial cavernoma of the falx cerebri and discuss radiological and pathological features in relation with existing literature.
Methods: We report a case of a 61-year-old female, who presented with progressive behavioral problems, gait disturbance, and memory loss over several years. Brain CT-scan and MRI showed an extra-axial lesion in relation to the anterior part of the falx cerebri. Because of mass effect and neuropsychological deficits, a surgical treatment was proposed.
Results: A bifrontal craniotomy was performed, and a bifrontal interhemispheric approach was used to resect the lesion. Pathological analysis revealed characteristics of a cavernous angioma. Post-operative clinical course was slowly favorable, and MRI showed complete resection of the malformation. Radiological and histological features of this rare entity are discussed.
Conclusion: We present a case of giant calcified extra-axial cavernoma of the falx cerebri. Radiological, surgical, and histological features of this rare lesion are presented, and discussed in relation with existing literature.
