Basic Arterial Anatomy and Interpretation of CT Angiography for Intra-Abdominal or Gastrointestinal Bleeding: Correlation with Conventional Angiographic Findings for Beginners

It is essential to identify the causative artery in case of active intra-abdominal or gastrointestinal bleeding. A thorough understanding of the basic arterial anatomy is required to identify the causative artery on contrast-enhanced CT angiography and conventional catheter angiography. If one is familiar with the basic arterial anatomy, obtaining access to the bleeding artery will be easier, despite the variations in the origin and course of the vessels. We describe the basic arterial anatomy that will help beginners in diagnostic radiology to identify the blood vessels that can cause active intra-abdominal or gastrointestinal bleeding.

Intractable Headache Related to Intraventricular Glioblastoma: A Case Report and Literature Review

Although various neoplasms may develop in the ventricular system, glioblastomas are rare. An 80-year-old woman visited our hospital with intractable headache related to a right ventricular large mass, which exhibited heterogeneous enhancement involving the body, trigone, and occipital horn of the right lateral ventricle on MRI. The mass was diagnosed as glioblastoma multiforme on surgical pathology. Herein, the authors present a case and review the existing literature with regarding to incidence, pathophysiology, prognostic factors, imaging and pathologic findings of intraventricular glioblastoma multiforme.
