Solitary Intraventricular Hemorrhage Without Subarachnoid Hemorrhage Due to Aneurysmal Rupture: A Case Report


Solitary Intraventricular Hemorrhage Without Subarachnoid Hemorrhage Due to Aneurysmal Rupture: A Case Report

Seung Soo Kim et al. J Cerebrovasc Endovasc Neurosurg.


The presence of primary intraventricular hemorrhage (IVH) without vascular lesion is very rare. We experienced solitary IVH without subarachnoid hemorrhage due to aneurysmal rupture in a 58-year-old man treated with coil embolization, which contributed to his good prognosis. After 33 days of hospitalization, he had mild right hemiplegic symptoms remaining, and he was transferred to a rehabilitation institute for further treatment. In cases of primary IVH, computed tomography angiography seems worthwhile for making a differential diagnosis, although the possibility of IVH due to cerebral aneurysmal rupture is very low. Endovascular intervention is a good option for diagnosis and treatment.

Fig. 1. The initially checked non-contrast-enhance computed tomography scans. A: The hemorrhage is expanded through the foramen Monro to the contralateral anterior horn of the lateral and third ventricles. B: No definite subarachnoid hemorrhage is observed on the initial computed tomography scan.
