Multidetector Computed Tomography and Magnetic Resonance Imaging Evaluation of Craniovertebral junction Abnormalities.

Background: Craniovertebral junction (CVJ) abnormalities constitute an important group of treatable neurological disorders with diagnostic dilemma. Their precise diagnosis, identification of probable etiology, and pretreatment evaluation significantly affects prognosis and quality of life of patients.

Aims: The study was to classify various craniovertebral junction disorders according to their etiology and to define the importance of precise diagnosis for pretreatment evaluation with multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI).

Crohns disease with central nervous system vasculitis causing subarachnoid hemorrhage due to aneurysm and cerebral ischemic stroke.

Cerebral vasculitis secondary to Crohn's disease (CD) seems to be a very rare phenomenon. We report a 39-year-old male who presented with headache, vomiting, and left-sided weakness in the known case of CD. Cross-sectional imaging (computed tomography and magnetic resonance imaging,) showed right gangliocapsular acute infarct with supraclinoid cistern subarachnoid hemorrhage (SAH).
