IV. Learning unit: Subarachnoid haemorrhage

Objectives and competencies

This syllabus introduces clinico-pathological relevancies of subarachnoid haemorrhage in multidisciplinary approach. The anatomical chapter describes general structure of the subarachnoid space and cisterns and their two categories the infra and supratentorial cisterns. The pathological chapter introduces the clinical course of subarachnoid haemorrhage, etiology of berry aneurysm formation, pathology of infective aneurysms formation, their morphological features and intracranial vascular malformations. Students may learn general radiological characteristics of subarachnoid haemorrhage on CT and MR imaging and may learn of DSA which is considered the gold standard diagnostic imaging modality of subarachnoid haemorrhage. The clinical chapter introduces epidemiology, clinical course, symptomatology, non-imaging tools of diagnosis, differential diagnosis and treatment modalities in multimedia enhanced environment with illustrations photos and tables.

IV/1.1: Introduction

The brain and the spinal cord is covered by three meninges; the outer membrane is hard and the two inner membranes are soft. The hard meninx (pachymeninx) is called dura mater, while the outer soft meninx (leptomeninx) is called arachnoid mater (spider web membrane), and the inner is pia mater.
