Third ventricle cavernoma associated with multiple intracerebral cavernomas

A 30-year-old young male was referred to our department complaining of headaches and visual disturbances over the last few weeks. Physical examination was unremarkable. A brain MRI revealed a third ventricle mass protruding in the suprasellar cistern and compressing the optic chiasm. The lesion showed increased signal intensity on both T1 and T2-weighted images combined with a halo of decreased signal on T2 images due to hemosiderin (Fig. 1). T2 GRE images revealed multiple lesions of low signal intensity in periventricular areas, left parietal cortex and right frontal white matter area (Fig. 2) The findings were compatible with intraventricular and intracerebral cavernomas. Surgical resection of the intraventricular lesion was performed via a transcallosal transventricular approach. Pathological examination confirmed the diagnosis of cavernous angioma. Postoperative course was uneventful.
