Intraventricular cerebral cavernomas: a series of 12 patients and review of the literature

Abstract

In the present series, the IVCs had a high tendency for rehemorrhage. Surgery is advocated when hemorrhages are frequent, and the mass effect causes progressive neurological deficits. Microsurgical removal of the IVC is safe, but in the fourth ventricle it can carry increased risk for cranial nerve deficits.

Giant intraventricular mass arising from the septum pellucidum

“…Even though the first patient with an intraventricular cavernoma was reported as early as 1905, very few patients have been reported since then. 1 The third ventricle is the most common site for intraventricular cavernomas, with location at the foramen of Monro being rare. Lack of characteristic MRI features, including the peripheral hypointense rim, and the non-specific features of other common intraventricular tumors on MRI, precludes preoperative diagnosis of an intraventricular cavernoma.…”

Characteristics of cavernomas of the brain and spine

“…The same appearance was noted in patients with intraventricular cavernomas; in our series of 12 patients with intraventricular lesions, re-bleeding occurred in half of the patients, and the annual risk was extremely high, 89% per patient. 77 In contrast to previous studies, Barker et al proposed the concept of temporal clustering of the hemorrhages after the initial event. 24 Cavernoma hemorrhage may be provoked by the use of anticoagulant therapy.…”

The clinical value of indocyanine green angiography in the microsurgery of brain cavernomas is very limited

“…Intraventricular lesions [1] can be visualized well with minimal parenchymal exposure necessary but there were none in the series of Murakami et al [3]. The authors did not classify their CCMs according to the Zabramski radiological classification based on the stage of intraluminal thrombosis of the lesion [4].…”
