Left Deep Frontal Cavernous Angioma Mimicking a Glioma in an Adult Patient

Cerebral cavernous angiomas are vascular malformations characterized by large adjacent vessels. Usually, these lesions are smaller than 3 cm, the mean age at presentation occurs between 20 and 40 years, and the neuroradiological findings are well described, especially for magnetic resonance imaging, where the "popcorn balls" appearance is due to the presence of locules containing blood. Among these, the giant cavernous angiomas are very rare, particularly in adults. We collected clinical and neuroradiological data from clinical file and hospital diagnostic archive. A comprehensive review of similar cases was performed. We describe the clinical, diagnostic, and surgical management of a giant cerebral cavernous angioma located in the left deep frontal lobe mimicking a high-grade glioma in an adult Chinese patient. Giant cerebral cavernous angioma may be misdiagnosed and should be considered as differential diagnosis.
