Abstract
Background: Cavernous hemangiomas are common benign vascular malformations. Their existence in the intraventricular region is very rare. Case Reports: A 43-year old woman with an occipital headache was admitted to the emergency ward. Brain computed tomography scan showed mild hydrocephalus and multiple intraventricular isodense lesions. Imaging findings, especially of Gradient Resonance Echo imaging, were in favor of multiple intraventricular cavernous malformations. Conclusion: This is a rare presentation of multiple cavernous malformation as occipital headache without needing surgical intervention in this phase. Coexistence of periventricular plaques like Radiologically isolated syndrome of Multiple sclerosis is another unique aspect in this report. [GMJ.2017;6(1):61-65]
Highlights
Cavernous malformation (CM) or cavernoma of the central nervous system are vascular malformations that usually present in the cerebral hemispheres
Due to the rarity of these lesions in the intraventricular region and multiplicity of them in various ventricles and difficulty of diagnosis without special magnetic resonance imaging (MRI) techniques, we reported this case for educational objectives
These findings suggest multiple sclerosis (MS), no clinical sign and symptom in favor of MS were present
Summary
Cavernous malformation (CM) or cavernoma of the central nervous system are vascular malformations that usually present in the cerebral hemispheres. It constitutes 5-10% of vascular malformations occurring in the central nervous system and commonly seen in the 2nd-5th decades of life [1] Their existence in the intraventricular region is very rare, constituting 2.5-10% of all cerebral CM [1, 2]. Especially of GRE images, were in favor of multiple intraventricular CMs. Incidentally, multiple T2-FLAIR hyperintense lesions were seen in the white matter of cerebral hemispheres including deep periventricular and juxtacortical regions without enhancement in the post-contrast images. Multiple T2-FLAIR hyperintense lesions were seen in the white matter of cerebral hemispheres including deep periventricular and juxtacortical regions without enhancement in the post-contrast images These findings suggest multiple sclerosis (MS), no clinical sign and symptom in favor of MS were present. No deterioration was seen in the patients, five months after discharging from the hospital
