With Ventricular Tachyarrhythmias and Normal Coronary Arteriograms To the Editor: Ouyang et al1 report on 4 patients with recurrent exerciseinduced syncope attributable to fast ventricular tachycardia, aneurysms in the inferior-lateral wall of the left ventricle, and a peculiar subepicardial arrhythmogenic substrate. The authors speculate that this presentation may constitute a distinct clinica...

Two patients with intraventricular hemorrhage (IVH) were treated by direct removal of their intraventricular hematomas via a high occipital transcortical approach with successful results. This approach lies between the parietooccipital transcortical approach and the occipital transcortical approach. The patients were a 90-year-old woman with idiopathic IVH and a 60-year-old man with hemorrhage ...

Detailed fetal intracranial anatomy can be examined in utero using real-time sonography. The ability to demonstrate motion makes it possible to visualize important vascular landmarks which are helpful in identifying adjacent structures and in recognizing appropriate planes of section. The lateral ventricular system can be demonstrated and the lateral ventricular ratio can be determined in case...

The purpose of this study is to present and document the rare and dynamic behavior of an ependymal cyst. We report 18 months old Caucasian girl who presented with multiple episodes of intermittent ataxia and vomiting with unremarkable neurological examination. Non contrast head CT was consistent with marginally dilated right lateral ventricle. MRI showed 1.7 × 1.5 × 1.1 cm cystic structure at t...

The floor of the fourth ventricle in the mouse was studied by scanning and transmission electron microscopy. 1. The fourth ventricular floor is covered by a simple layer of ependymal cells, the cytoplasm of which is characterized by numerous filaments and scanty ribosomes. 2. The ventricular surface of the ependyma is studded with numerous cilia and abundant microvilli. In the medial part of th...

tumors and the usual location for intracranial germinomas is the midline structures such as the pineal and suprasellar regions (1). To the best of our knowledge, intracranial germinoma primary arising in the lateral ventricle has not yet been reported in the medical literature. We describe here a case of lateral ventricular germinoma that showed rapid progression and it mimicked choroid plexitis.
